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.
