1. A method of wirelessly monitoring a subject in real time using a removable device worn on the subject, said method comprising:
- wirelessly capturing an acoustic signal using a sensor located within the removable device worn on the subject, the acoustic signal being indicative of breathing over a first period of time;
inputting, at a processor located within the removable device worn on the subject, a first signal indicative of the captured acoustic signal from the sensor;
removing, at the processor, noise from the first signal to create a second signal indicative of the breathing;
computing, at the processor, a plurality of moving averages of the second signal using a temporal window defining a second period of time, wherein each moving average is an average value of the second signal across the temporal window;
determining, at the processor, that at least one of the plurality of moving averages has a value of zero;
identifying, at the processor, an apneic event in response to the determining; and
reporting the identified apneic event using a visual display.

Abstract
A wearable patch and method for automatically monitoring, screening, and/or reporting events related to one or more health conditions (e.g., sleeping or breathing disorders, physical activity, arrhythmias) of a subject.

10. A device for wirelessly monitoring a subject in real time, said device being configured to be worn on a body of the subject and comprising:
-
an acoustic sensor for wirelessly capturing an acoustic breathing signal continuously over a first period of time; a visual display; and a processor in communication with said acoustic sensor and visual display, said processor adapted to; input a first electrical breathing signal indicative of the captured acoustic signal from the acoustic sensor, remove noise from the captured first electrical breathing signal to create a second breathing signal, compute a plurality of moving averages of the second breathing signal using a temporal window defining a second period of time, wherein each moving average is an average value of the second breathing signal across the temporal window, determine that the at least one of the plurality of moving averages has a value of zero, identify an apneic event in response to the determining, and report the identified apneic event using the visual display. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
