A system for aiding a user includes a stimulator, a sensor, a memory, and a control system. The stimulator is configured to be positioned in the user adjacent to an airway of the user. The sensor is configured to generate data associated with the airway of the user. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions to determine, based at least on an analysis of the generated data, that the user is currently experiencing an apnea event. In response to the determination that the user is currently experiencing an apnea event, the control system causes the stimulator to provide electrical stimulation, at a first intensity level, to one or more muscles of the user that are adjacent to the airway to aid in stopping the apnea event.

A method and a system for measuring inspiratory/expiratory air flow rate from inhalation/expiration near a microphone of an electronic device by a user. An inhaler is selected by the user among a plurality of possible inhalers, and the user is prompted to perform an inhalation/expiration close to a microphone of the computing device. Sound is measured during inhalation/expiration and sound data derived therefrom. There is determined the inspiratory/expiratory air flow rate by comparing the collected sound data with a flow rate data set used by the industrially calibrated device and stored in an inhaler-appropriate flow-rate database, and if the inspiratory/expiratory air flow rate is within a predetermined range for the selected inhaler, thereby determining whether the selected inhaler is one of the appropriate inhalers for the inspiratory/expiratory flow measured by comparing the determined inspiratory/expiratory air flow rate with a range of inspiratory/expiratory air flow rates corresponding to the selected inhaler.

A respiration rate measurement apparatus including a plurality of sensors for concurrently generating temperature, pressure and acoustic data representing one or more successive breaths and a method of generating fusion data from the plurality of data streams as a weighted average based on determined correlation coefficients and calculation of a respiratory rate.

A mask apparatus including a mask body that defines a communication hole, a sensor mounting portion that extends from a front surface of the mask body, that surrounds the communication hole, and that defines an installation space therein, a seal coupled to a rear surface of the mask body and configured to define a breathing space between the mask body and a user, a pressure sensor accommodated in the installation space and configured to sense air pressure inside the breathing space that is in communication with the communication hole, and a film disposed in the installation space and configured to restrict permeation of moisture from the breathing space into the installation space through the communication hole.

A percutaneous electrical phrenic nerve stimulation (PEPNS) system that measures the patient Work of Breathing (WOB) of each type of ventilator breath and determines when to deliver electrical stimulus based upon the measured WOB. The PEPNS system alters its behavior based upon the type and origin of the ventilator breath delivered and provides warnings for certain identified interactions between the ventilator and the patient.

Breath sensor apparatus and methods of use are described herein where a flow control apparatus may generally comprise a sampling chamber defining a volume and one or more openings into the sampling chamber, at least one sensor in fluid communication with the sampling chamber, wherein the at least one sensor is configured to detect the analyte. The sampling chamber may also be configured to receive the breath sample into the sampling chamber and into contact with the at least one sensor via diffusion into the sampling chamber.

An analyzer for diagnosing pulmonary and abdominals including, a pulsed force generator for outputting a mechanical disturbance to generate vibrations and reflected/return waves/vibrations in a patient's torso, and sensors for detecting the vibration/return wave signals. The apparatus compares the detected electrical signals with pre-stored reference wave profiles and based on the compared data generates an output signal indicative of a potential presence or absence of a pulmonary disease and/or condition.

A method of cough detection in a headset, the method comprising: receiving a first signal from an external transducer of the headset; receiving a second signal from an in-ear transducer of the headset; and detecting a cough of a user of the headset based on the first and second signals.

An integrated cardio-respiratory system that fuses continuously recorded data from multiple physiological sensor sources to acquire signals representative of acoustic events caused by physiological phenomena occurring in the cardiac and/or arterial structures underneath particular areas of the chest and/or neck to monitor cardiac and respiratory conditions.

A physiological acoustic monitoring system receives physiological data from an acoustic sensor, down-samples the data to generate raw audio of breathing sounds and compresses the raw audio. The acoustic monitoring system has an acoustic sensor signal responsive to tracheal sounds in a person. An A/D converter is responsive to the sensor signal so as to generate breathing sound data. A decimation filter and mixer down-samples the breathing sound data to raw audio data. A coder/compressor generates compressed audio data from the raw audio data. A decoder/decompressor decodes and decompresses the compressed audio data into decompressed audio data. The decompressed audio data is utilized to generate respiration-related parameters in real-time. The compressed audio data is stored and retrieved so as to generate respiration-related parameters in non-real-time. The real-time and non-real-time parameters are compared to verify matching results across multiple monitors.
