A system and method using a microphone to collect sound data produced by a potential patient's respiration and speech. The system preferably uses a microphone on a portable electronic device—such as a smart phone. The analysis of the collected data is preferably performed locally—such as by a software application running on the smartphone. The software is used to analyze the data and therefore determine and track useful parameters such as respiration rate and respiratory tidal volume. The software also analyzes phonation patterns. Using the parameters, the inventive system can detect the onset of respiratory distress.

A device, system and method for monitoring a pulmonary system of a subject. An optical member for emitting a light signal through a cavity of the pulmonary system of the subject. The optical member and a detector unit are configured to be positioned so that the light signal detected that has ebb transmitted from the optical member through the cavity. A control unit is configured for evaluating the detected light signal for determining a physiological status of said pulmonary system of the subject.

Apparatus for medical screening includes a plurality of acoustic transducers, which are configured to sense acoustic waves emitted from a body of a subject and to output signals in response thereto. A frame is configured to position the acoustic transducers in proximity to a thorax of the subject, so that the acoustic transducers receive the acoustic waves emitted from different, respective locations on the thorax. Processing circuitry is configured to collect and process the signals so as to assess a respiratory condition of the subject and to issue an alarm upon detecting a pathological respiratory condition, such as a suspicion of COVID-19.

In a method for correcting the interference in respiratory navigation, transmitting, during magnetic resonance scanning, a respiratory signal generated by a radio frequency signal generator to a human body; acquiring, as a measured respiratory signal, a respiratory signal passing through the human body and acquired in a local coil, wherein the measured respiratory signal is constituted by a real respiratory signal and an interference signal; determining, according to a respiratory signal coil sensitivity of the real respiratory signal and an interference signal coil sensitivity of the interference signal, a signal relation that is satisfied by the real respiratory signal, the interference signal and the measured respiratory signal; and calculating the signal relation to obtain the real respiratory signal.

The present disclosure provides systems, apparatuses and methods that provide probe-cavity location and motion data based on probe location and respiration data.

A smart clothes for sensing heart physiological activities and lung respiratory conditions is provided, the smart clothes utilizes conductive connecting elements for being externally connected to a control module, such that the control module can be expanded or upgraded according to functional requirements. Further in the smart clothes, sensing elements and signal transmission wires are made of conductive fabric. As the conductive fabric sensing elements and signal transmission wires are well attached to a clothing body of the smart clothing, the sensing elements can be better adhered to human skin, and thereby sensing accuracy is improved.

Systems and methods provide for assessing the heart failure status of a patient and, more particularly, to generating a trend parameter based on a distribution of the patient's respiration rate. Systems and methods provide for detecting, using an implantable device or a patient-external device, patient respiration and computing a respiration rate based on the detected patient respiration. A distribution of the respiration rate is calculated, and a trend parameter based on the respiration rate distribution is generated. The trend parameter is indicative of a patient's heart failure status. An output signal indicative of the patient's heart failure status may be generated based on the trend parameter.

A ventilator (1) with a respiratory device (2) for generating a respiratory gas flow for a ventilation and with a monitoring device (3) for monitoring a characteristic parameter (200) of the respiratory gas flow. A control device (4) is provided here and is suitable and configured to carry out a detection mode for a cardiac activity and to register for this a temporal profile (201) of the parameter (200) of the respiratory gas flow and to examine the temporal profile (201) of the parameter (200) for a profile structure feature (202) and to detect heartbeats in that the profile structure feature (202) fulfils a stored condition for a profile structure feature (202) which is caused by heartbeat.

A system and method for automatically implementing a therapy for treating sleep disordered breathing.

A measuring device for determining the CO.sub.2 content in the exhaled air of a living being, for example, a person or a mammal. The device may have a measuring tube defined by a wall, said measuring tube having an air inlet and an air outlet, with an inlet and an air outlet, with a CO.sub.2 measuring device having a sensor pot which is in fluid communication with the measuring tube. The sensor pot extends through the wall of the measuring tube into the interior of the measuring tube, wherein the diameter of the measuring tube is reduced in the region of the sensor pot. The sensor pot is substantially open towards the measuring tube, such that the sensor pot is configured for direct measurement of the CO.sub.2 content of air exhaled through the measuring tube, past the sensor pot.
