No. 62/505,762, filed May 12, 2017, and also claims priority benefit under 35 U.S.C. § 119(e) from U.S. Provisional Patent Application Ser. No. 62/447,836, filed Jan. 18, 2017, titled “PATIENT-WORN WIRELESS PHYSIOLOGICAL SENSOR WITH PAIRING FUNCTIONALITY”, the disclosure of which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure relates to the field of pairing of wireless communication devices. More specifically, the disclosure describes among other things a portable wireless device that communicates with a second device capable of wireless communication with paired electronic devices.

BACKGROUND

In clinical settings, such as hospitals, nursing homes, convalescent homes, skilled nursing facilities, post-surgical recovery centers, and the like, patients are frequently monitored using one more different types of physiological sensors. Various types of sensors include a magnetometer that detects patient movement or orientation to track and prevent patient ulcers, a temperature sensor, an acoustic respiration sensor, an electrocardiogram (ECG) sensor, an electroencephalography (EEG) sensor, one or more pulse oximetry sensors, a moisture sensor, a blood pressure sensor, and an impedance sensor, among other sensors.
Wires leading to and from traditional physiological sensors inhibit patient movement and make it difficult to provide care to a patient. Often sensors are accidentally removed by patient movement. At other times, sensors must be moved or replaced when a patient is moved to a different location or when certain types of care are provided to the patient. Wireless sensors provide a solution to the patient movement and access. However, in busy hospital environments with non-technical staff operating these wireless devices, it can be difficult to correctly configure wireless sensors for communication with the correct monitors.
Similarly, other wireless devices including consumer devices such as, but not limited to, speakers, phones, headphones, watches, keyboards, mice, and so forth, capable of being paired have similar issues. These devices are often used by non-technically oriented users that encounter cumbersome pairing requirements.

DETAILED DESCRIPTION

FIG. 1A is a schematic assembled perspective view of wireless sensor 102. The wireless sensor 102 may also be referred to herein as “a wireless physiological sensor 102,” “a patient-worn sensor 102,” “a movement sensor 102,” and “a wearable wireless sensor 102.” The wireless sensor 102 includes one or more sensors configured to measure the patient's position, orientation, and motion. Also illustrated in FIG. 1A is a button or switch 124 located on a top portion of the housing 150. The button or switch 124 can be used to change modes of the wireless sensor 102. For example, pressing and holding the button or switch 124 can cause the wireless sensor 102 to switch into a pairing mode of operation. The pairing mode is used to associate the wireless sensor 102 with a mobile device 210 as shown in FIGS. 2A-B or a bedside patient monitor 310 as shown in FIGS. 3A-B. Wireless sensor 102 may include one or more detecting elements such as: a magnetometer which may also be referred to as a compass, a temperature sensor, an acoustic respiration sensor, an electrocardiogram (ECG) sensor, an electroencephalography (EEG) sensor, one or more pulse oximetry sensors, a moisture sensor, a blood pressure sensor, and an impedance sensor.
The magnetometer may be a three-dimensional magnetometer that provides information indicative of magnetic fields, including the Earth's magnetic field. A skilled artisan will understand that the accelerometer, gyroscope, and magnetometer can be integrated into a single hardware component such as an inertial measurement unit. The wireless sensor 102 may be configured to calculate the three-dimensional position and orientation of an object derived from inputs from three sensors attached to the object: an accelerometer configured to measure linear acceleration along three axes; a gyroscope configured to measure angular velocity around three axes; and a magnetometer configured to measure the strength of a magnetic field (such as the Earth's magnetic field) along three axes. The three sensors may attach to the wireless sensor 102 which is affixed to the patient. The sensors may be sampled at a rate between approximately 10 Hz and approximately 100 Hz. One skilled in the art will appreciate that the sensors can be sampled at different rates without deviating from the scope of the present disclosure. The sampled data from the three sensors, which provide nine sensor inputs, are processed to describe the patient's position and orientation in three-dimensional space. The patient's position and orientation are described in terms of Euler angles as a set of rotations around a set of X-Y-Z axes of the patient.
An acoustic respiration sensor can be used to sense acoustic and/or vibrational motion from the patient's body (e.g., the patient's chest) that are indicative of various physiologic parameters and/or conditions, including without limitation, heart rate, respiration rate, snoring, coughing, choking, wheezing, and respiratory obstruction (e.g., apneic events). The ECG sensor can be used to measure the patient's cardiac activity. The ECG sensor may include two electrodes and a single lead. The pulse oximetry sensor(s) can be used to monitor the patient's pulse oximetry, a widely accepted noninvasive procedure for measuring the oxygen saturation level of arterial blood, an indicator of a person's oxygen supply. A typical pulse oximetry system utilizes an optical sensor clipped onto a portion of the patient's body (such as, for example, a fingertip, an ear lobe, a nostril, and the like) to measure the relative volume of oxygenated hemoglobin in pulsatile arterial blood flowing within the portion of the body being sensed. Oxygen saturation (SpO2), pulse rate, a plethysmograph waveform, perfusion index (PI), pleth variability index (PVI), methemoglobin (MetHb), carboxyhemoglobin (CoHb), total hemoglobin (tHb), glucose, and/or otherwise can be measured and monitored using the pulse oximetry sensor(s). The moisture sensor can be used to determine a moisture content of the patient's skin which is a relevant clinical factor in assessing the patient's risk of forming a pressure ulcer. The impedance sensor can be used to track fluid levels of the patient. For example, the impedance sensor can monitor and detect edema, heart failure progression, and sepsis in the patient.
FIG. 1B is a schematic exploded perspective view of wireless sensor 102 including a bottom base 110, a removable battery isolator 120, a mounting frame 130, a circuit board 140, a housing 150, and a top base 160. The bottom base 110 is a substrate having a top surface on which various components of the wireless sensor 102 are positioned, and a bottom surface that is used to affix the wireless sensor 102 to the patient's body. The bottom base 110 and top base 160 can be made of medical-grade foam material such as white polyethylene, polyurethane, or reticulated polyurethane foams, to name a few. As illustrated in FIG. 1A, the bottom base 110 and the top base 160 are each in a substantially oval shape, with a thickness of approximately 1 mm. The top base 160 includes a cut-out 162 through which the housing 150 fits during assembly. A skilled artisan will understand that there are numerous sizes and shapes suitable for the top and bottom bases 110 and 160 that can be employed without departing from the scope of the present disclosure. The bottom surface of the bottom base 110 is coated with a high tack, medical-grade adhesive, which when applied to the patient's skin, is suitable for long-term monitoring, such as, for example two days or longer. Portions of the top surface of the bottom base 110 are also coated with a medical-grade adhesive, as the bottom base 110 and the top base 160 are adhered together during assembly of the wireless sensor 102. The bottom base 110 may have apertures 112 and 114. These apertures 112 and 114 may permit transmission of thermal energy, electrical energy, light, sound, or any other input to the wireless sensor 102.
The removable battery isolator 120 is a flexible strip made of an electrically insulating material that serves to block electrical communication between the battery 144 and an electrical contact (not shown) on the circuit board 140. The battery isolator 120 is used to preserve battery power until the wireless sensor 102 is ready for use. The battery isolator 120 blocks electrical connection between the battery 144 and the circuit board 140 until the battery isolator 120 is removed from the wireless sensor 102. The battery isolator 120 can be made of any material that possesses adequate flexibility to be slidably removed from its initial position and adequate dielectric properties so as to electrically isolate the battery 144 from the circuit board 140. For example, the battery isolator 120 can be made of plastic, polymer film, paper, foam, combinations of such materials, or the like. The battery isolator 120 includes a pull tab 122 that extends through a slot 152 of the housing 150 when the wireless sensor 102 is assembled. The pull tab 122 can be textured to provide a frictional surface to aid in gripping and sliding the pull tab 122 out of its original assembled position. Once the battery isolator 120 is removed the battery 144 makes an electrical connection with the electrical contact to energize the electronic components of the wireless sensor 102.
The mounting frame 130 is a structural support element that helps secure the battery 144 to the circuit board 140. The mounting frame 130 has wings 132 that, when assembled are slid between battery holder 142 and the battery 144. Additionally, the mounting frame 130 serves to provide rigid structure between the circuit board 140 and the bottom base 110. The rigid structure, which may include an acoustic respiratory sensor, may transmit vibrational motion (vibrations) emanating from the patient (such as, for example, vibrational motions related to respiration, heartbeat, snoring, coughing, choking, wheezing, respiratory obstruction, and the like) to the accelerometer 149 positioned on the circuit board 140. The mounting frame 130 may have an aperture 134 that extends through the mounting frame 130. The aperture 134 may be aligned with the aperture 114 in the bottom base 110 as described above. The aperture 134 may permit transmission of thermal energy, electrical energy, light, sound, or any other input to the wireless sensor 102. The aperture 134 may be filled with a thermally conductive material.
A battery holder 142 is attached to two sides of the top portion circuit board 140 and extends (forming a support structure) under the bottom side of the circuit board 140 to hold the battery 144 in position relative to the circuit board 140. An electrical connection between the anode of the battery 144 and the circuit board 140 is made by way of the battery holder which is in electrical contact with the anode of the battery 144 and the circuit board 140. The cathode of the battery 144 is positioned to touch a battery contact (not shown) on the bottom side of the circuit board 140.
The housing 150 is a structural component that serves to contain and protect the components of the wireless sensor 102. The housing 150 can be made of any material that is capable of adequately protecting the electronic components of the wireless sensor 102 such as thermoplastics and thermosetting polymers. The housing 150 includes a slot 152 through which the battery isolator 120 is inserted during assembly. The housing 150 also includes a rim 154 that extends around the outer surface of the housing 150. The rim 154 is used to secure the housing 150 in position relative to the bottom base 110 and the top base 160 when the wireless sensor 102 is assembled.
Assembly of the wireless sensor 102 is as follows: the circuit board 140 and battery holder 142 holding the battery 144 are placed into the housing 150. The wings 132 of the mounting frame 130 are inserted in between the battery 144 and the battery holder 142, so as to align the mounting frame 130 with the circuit board 140. The battery isolator 120 is positioned between the electrical contact and the battery 144. The pull tab 122 of the battery isolator 120 is then fed through the slot 152 in the housing 150. The top base 160 is then positioned over the housing 150. The rim 154 of the housing 150 adheres to the bottom surface of the top base 160, which is coated with high tack, medical-grade adhesive. The resulting partial assembly is positioned centrally onto the top surface of the bottom base 110, aligning the edges of the base top 160 with the edges of the base bottom 110. The bottom surface of the bottom base 110 is then coated with a high tack, medical-grade adhesive, and a release liner (not shown) is placed on the bottom surface of the bottom base 110 to protect the adhesive until it is time for use.

The patient monitoring system includes a wireless sensor 102 worn by a patient in proximity to mobile device 210. The mobile device 210 includes screen 220 that may be configured to transmit and receive a visual, optical, and/or light-based pairing signal. The pairing signal may contain a pattern containing a shape, color, or a combination of patterns. The pairing signal may involve displaying instructions on a screen 220 for a user to follow. The instructions may include the user placing a wireless sensor 102 of a particular shape and size in a certain position relative to the screen 220. The instructions may be displayed using an object 214 on the screen 220 to represent the silhouette of the wireless sensor 102. To follow the instructions, the user may hold the wireless sensor 102 and position the wireless sensor 102 according to the instructions. The user may place the wireless sensor 102 to resemble the relative position of the object 214 displayed on the screen 220 of the mobile device 210.
The pairing signal may contain a series of visual, optical, and/or light based signals. The series of signals may utilize variations in color, shade, shape, or visual patterns. The pairing signal may contain a series of flashes, wherein the flashes may vary in intensity or duration. The pairing signal may comprise a combination of visual and audio signals.
For example, the wireless sensor 102 and the mobile device 210 may include a detector that detects visual, optical, or light-based signals and another detector for detecting audio sound or a series of audio sounds. A detector may be configured to detect both visual and audio signals. The pairing signal may include a sequence of visual signals that is synchronized with a sequence of audio signals.
Additionally, the screen 220 may be configured to display motion instructions for a care provider to perform in order to generate motion signals representing a pairing signal. Mobile device 210 may also generate audio-based pairing signals using a speaker (not shown). The sounds may be tuned to a frequency within or outside of the range of human hearing and may comprise various rings or tones. Additionally, the mobile device 210 may have a port for connecting peripheral devices that may generate various signals such as current or voltage based signals. The pairing signal may take the form of an electrical signal.

The instructions may include the user placing a wireless sensor 202 of a particular shape and size in a certain position relative to the screen 220. The shape and size of the wireless sensor 202 may differ from the shape and size of the wireless sensor 102. The instructions may be displayed using an object 216 on the screen 220 to represent the silhouette of the wireless sensor 202. To follow the instructions, the user may hold the wireless sensor 202 and position the wireless sensor 202 according to the instructions. The user may place the wireless sensor 202 to resemble the relative position of the object 216 displayed on the screen 220 of the mobile device 210.

The wireless sensor 202 may also include a button or switch 204. The button or switch 204 can be used to change modes of the wireless sensor 202. For example, pressing and holding the button or switch 204 can cause the wireless sensor 202 to switch into a pairing mode of operation. The pairing mode is used to associate the wireless sensor 102 with a mobile device 210 or a bedside patient monitor 310.
FIG. 3A is a perspective illustration of the patient monitoring system in a clinical setting. The patient monitoring system includes a wireless sensor 102 worn by a patient in proximity to a bedside patient monitor 310 located at the side of a patient's bed. The bedside patient monitor 310 may include screen 312 that may be configured to transmit a visual, optical, and/or light-based pairing signal. The pairing signal may contain a pattern containing a shape, color, or a combination of patterns. The pairing signal may involve displaying instructions on a screen 312 for a user to follow.

Additionally, the pairing signal may contain a series of flashes, wherein the flashes may vary in intensity or duration. Additionally, the screen 312 may be configured to display motion instructions for a care provider to perform in order to generate motion signals representing a pairing signal. Bedside patient monitor 310 may also generate audio-based pairing signals using a speaker (not shown). The sounds may be tuned to a frequency within or outside of the range of human hearing and may comprise various rings or tones. Additionally, the bedside patient monitor 310 may have a port 316 for connecting peripheral devices that may generate various signals such as current or voltage based signals. The pairing signal may take the form of an electrical signal.
The patient monitor 310 may have a button or switch 317 can be used to activate the patient monitor 310 and place it in the pairing mode of operation. Similarly the buttons or switches 318, 319 can also be used to activate the patient monitor 310 and place it in the pairing mode of operation. This process is discussed more below. When the button/switch 317 is depressed and/or continuously held down, the patient monitor 310 may enter into the pairing mode of operation.
FIG. 3B is a perspective illustration of the patient monitoring system in a clinical setting. The patient monitoring system includes a wireless sensor 202 worn by a patient in proximity to a bedside patient monitor 310 located at the side of a patient's bed. The bedside patient monitor 310 may include screen 312 that may be configured to transmit a visual, optical, and/or light-based pairing signal. The pairing signal may contain a pattern containing a shape, color, or a combination of patterns. The pairing signal may involve displaying instructions on a screen 312 for a user to follow.
Similar to FIG. 3A, the instructions may include the user placing a wireless sensor 202 of a particular shape and size in a certain position relative to the screen 312. The instructions may be displayed using an object 216 on the screen 312 to represent the silhouette of the wireless sensor 202. To follow the instructions, the user may hold the wireless sensor 202 and position the wireless sensor 202 according to the instructions. The user may place the wireless sensor 202 to resemble the relative position of the object 216 displayed on the screen 312 of the bedside patient monitor 310.
Although described with respect to a bedside patient monitor 310, it is to be understood that mobile device 210 may also perform some or all of the functionality described in relation to bedside patient monitor 310. For example, wireless sensor 102 may pair with either the mobile device 210 or bedside patient monitor 310. Additionally, one skilled in the art will appreciate that numerous types of patient-specific information may be collected and analyzed by either the mobile device 210 or bedside patient monitor 310. Therefore, it is to be understood that patient monitoring system may be implemented with a mobile device 210 or a bedside patient monitor 310.
In some scenarios, it may be desirable to pair, or associate, the wireless sensor 102 with the bedside patient monitor 310 or mobile device 210 to avoid interference from other wireless devices and/or to associate patient-specific information (stored, for example, on the patient monitor 310) with the sensor data that is being collected and transmitted by the wireless sensor 102. Illustratively, such patient-specific information can include, by way of non-limiting example, the patient's name, age, gender, weight, identification number (e.g., social security number, insurance number, hospital identification number, or the like), admission date, length of stay, physician's name and contact information, diagnoses, type of treatment, perfusion rate, hydration, nutrition, pressure ulcer formation risk assessments, patient turn protocol instructions, treatment plans, lab results, health score assessments, and the like. One skilled in the art will appreciate that numerous types of patient-specific information can be associated with the described patient-worn sensor without departing from the scope of the present disclosure. Additionally, pairing the wireless sensor 102 with the mobile device 210 or bedside patient monitor 310 can be performed to provide data security and to protect patient confidentiality. Some wireless systems require the care provider to program the wireless sensor 102 to communicate with the correct mobile device 210 or bedside patient monitor 310. Other wireless systems require a separate token or encryption key and several steps to pair the wireless device 102 with the correct bedside patient monitors 310. Some systems require the token to be connected to the mobile device 210 or the bedside patient monitor 310, then connected to the wireless device 102, and then reconnected to the mobile device 210 or bedside patient monitor 310. In certain scenarios, it may be desirable to share wireless communication information between a wireless sensor 102 and a mobile device 210 or bedside patient monitor 310 without a separate token or encryption key. For security purposes, it may be desirable to use security tokens to ensure that the correct patient monitor 310 receives the correct wirelessly transmitted data. Security tokens prevent the mobile device 210 or bedside patient monitor 310 from accessing the transmitted data unless the wireless sensor 102 and mobile device 210 or patient monitor 310 share the same password. The password may be a word, passphrase, or an array of randomly chosen bytes.
FIG. 4 illustrates a method of associating a wireless sensor 102 with a mobile device 210 or a bedside patient monitor 310, which may be referred to as “pairing.” At block 402A, the wireless sensor 102 may be placed near the mobile device 210 or the bedside patient monitor 310 in preparation for receiving a pairing signal. A visual, optical, and/or light-based detector 146 of the wireless sensor 102 may be physically oriented and configured to receive a pairing signal in the form of a visual, optical, and/or light-based pairing signal. The pairing signal may contain a pattern containing a shape, color, or a combination of patterns. The pairing signal may contain a series of visual, optical, and/or light based signals. The series of signals may utilize variations in color, shade, shape, or visual patterns. Additionally, the pairing signal may contain a series of flashes, wherein the flashes may vary in intensity or duration. The signal may be unique to the wireless sensor 102 and the mobile device 210 or the bedside patient monitor 310. By using a pairing signal that uniquely identifies the wireless sensor 102 and the mobile device 210 or the bedside patient monitor 310, a secure connection may be established between the two paired devices.
Various types of sensors can be used with the pairing process of the present disclosure. For example, a pulse oximeter sensor can be paired by facing its light detector toward a bedside patient monitor screen 312 or mobile device screen 220 to receive a visual, optical, and/or light based signal. In another example, an ulcer sensor can be paired by receiving a pairing signal in the form of detected motion. Similarly, other types of wireless sensors can be paired using the included detectors. For example, an acoustic sensor can be paired based on audio signals emitted from the patient monitor 310. EEG and ECG wireless sensors can be paired using small electrical impulses from a special conductor included as part of the patient monitor 310. Other sensors can be paired in a similar fashion depending on the specific detectors included on the wireless sensors.
Returning to block 402A, the wireless sensor 102 may be placed in proximity to the mobile device 210 or the bedside patient monitor 310 such that the visual, optical, and/or light-based detector 146 may receive the visual, optical, and/or light-based pairing signal. The visual, optical, and/or light-based pairing signal may have a pairing signal transmission range of up to approximately three inches. The visual, optical, and/or light-based pairing signal may have a pairing signal transmission range of up to approximately six inches. The visual, optical, and/or light-based pairing signal may have a pairing signal transmission range of up to approximately one foot (i.e., twelve inches) or farther. A skilled artisan will recognize that other ranges can be used for the pairing signal transmission range.
At block 404A the wireless sensor 102 is set to operate in a pairing mode. A user may begin by initiating the pairing mode of operation for the wireless sensor 102. This may include powering on the wireless sensor 102, switching the wireless sensor 102 to a special pairing state, and/or the like. For example, the wireless sensor 102 may include a battery isolator 120 which, when removed, activates the wireless sensor 102. Upon activation, the default mode of operation is the pairing mode. The wireless sensor 102 may have a button or switch 124 that can be used to activate the wireless sensor 102 and place it in the pairing mode of operation. For example, a depressible button or switch 124 can be located on the top portion of the housing 150. When the button or switch 124 is depressed and continuously held down, the wireless sensor 102 enters into the pairing mode of operation and remains in the pairing mode of operation for as long as the button or switch 124 is depressed. The wireless sensor 102 enters into the pairing mode by activating the visual, optical, and/or light-based sensor 146. Once activated, the optical sensor 146 may be configured to receive the visual, optical, and/or light-based pairing signal.

When the button or switch 317 is depressed and/or continuously held down, the patient monitor 310 enters into the pairing mode of operation. Similarly, the mobile device 210 may have a button or switch that can be used to activate the mobile device 210 and place it in the pairing mode of operation.

The pairing signal transmission is received by orienting the visual, optical, and/or light-based detector 146 of the wireless sensor 102 toward the mobile device screen 220 or the patient monitor screen 312. The limited range of the visual, optical, and/or light-based pairing signal helps to prevent unintended or incidental association of the wireless sensor 102 with a mobile device 210 or bedside patient monitor 310 that might be nearby but which is not intended to be paired with the wireless sensor 102. Such circumstances can occur in hospitals, healthcare facilities, nursing homes, and the like where wireless sensors 102 mobile devices 210, and bedside patient monitors 310 are located in close physical proximity to one another.
At block 408, the wireless sensor 102 detects the pairing signal from bedside patient monitor 310 or mobile device 210. Upon detection of the pairing signal, at block 410, the wireless sensor 102 associates with the bedside patient monitor 310 thereby configuring the wireless sensor 102 and mobile device 210 or the patient monitor 310 to communicate with each other. Once the pairing is completed, the wireless sensor 102 transmits a confirmation signal confirming that the patient-worn sensor 102 is associated with the mobile device 210 or the bedside patient monitor 310, thereby indicating that the pairing process has been successfully completed, as reflected in block 412.

For sensors that utilize an audio sensor, such as respirator sensor, the pairing signal may be an audio sound or a series of audio sounds. A sound or audio-based detector 147 of the wireless sensor 102 may be configured to receive a pairing signal in the form of a sound or audio-based pairing signal. The sounds may be tuned to a frequency within or outside of the range of human hearing and may comprise various rings, chimes, or tones. The series of audio sounds may utilize variations in volume or tone to transmit pairing information. The signal may be unique to the wireless sensor 102 and the mobile device 210 or the patient monitor 310.

The mobile device 210 or the bedside patient monitor 310 is configured to emit a pairing signal. The speaker of the mobile device 210 or the bedside patient monitor 310 may be configured to emit an audio signal or a series of audio sounds as the pairing signal. The pairing signal transmission is received by orienting the audio or sound-based detector 147 of the wireless sensor 102 toward the bedside patient monitor 310 or mobile device 210. The limited range of the audio or sound-based pairing signal helps to prevent unintended or incidental association of the wireless sensor 102 with a mobile device or bedside patient monitor 310 that might be nearby but which is not intended to be paired with the wireless sensor 102. Such circumstances can occur in hospitals, healthcare facilities, nursing homes, and the like where wireless sensors 102 and the mobile device 210 or the bedside patient monitor 310 are located in close physical proximity to one another.

Upon detection of the pairing signal, the wireless sensor 102, at block 510, associates with the mobile device 210 or the bedside patient monitor 310 thereby configuring the wireless sensor 102 and patient monitor 310 to communicate with each other. Once the pairing is completed, the wireless sensor 102 transmits a confirmation signal confirming that the patient-worn sensor 102 is associated with the mobile device 210 or the bedside patient monitor 310, thereby indicating that the pairing process has been successfully completed, as reflected in block 512. At block 514, the mobile device 210 or the bedside patient monitor 310 receives the confirmation signal. And at block 516A, the wireless sensor 102 exits the pairing mode of operation and enters into a patient parameter sensing mode of operation. Similarly, at block 516B, the mobile device 210 or the bedside patient monitor 310 enters a patient parameter sensing mode of operation. In the patient parameter sensing mode of operation, the patient-worn sensor 102 transmits a patient parameter sensing signal having a patient parameter sensing signal transmission range. The wireless sensor 102 increases the power of the patient parameter sensing signal transmission range to a standard operating range, such as for example, approximately three meters. The patient parameter sensing signal transmission range may be approximately ten feet. Alternatively, the patient parameter sensing signal transmission range may be approximately thirty feet. The pairing signal transmission range may be between approximately three and twelve inches, while the patient parameter sensing signal transmission range may be approximately ten feet. There may be at least an order of magnitude difference between the pairing signal transmission range and the patient parameter sensing signal transmission range. Thus, the pairing signal transmission range is substantially less than the patient parameter sensing transmission range. Once the wireless sensor 102 enters into the patient parameter sensing mode of operation, the wireless sensor 102 is then in condition to be placed on the patient to perform sensing and monitoring functions.
