1. A self-contained personal air flow sensing monitor recorder, comprising:

  • a sealed housing adapted to be removably secured into a non-conductive receptacle on a disposable extended wear electrode patch; and

    an electronic circuitry comprised within the sealed housing, comprising;

    an externally-powered micro-controller operable to execute under micro programmable control and electrically interfaced to one or more respiratory sensors comprising an air flow sensor and at least one of an SpO2 sensor, a pCO2 sensor, and a respiratory rate sensor, the one or more respiratory sensors comprised within at least one of the disposable extended wear electrode patch and the sealed housing;

    an electrocardiographic front end circuit electrically interfaced to the micro-controller and operable to sense electrocardiographic signals through electrocardiographic electrodes provided on the disposable extended wear electrode patch, each of the electrocardiographic electrodes adapted to be positioned axially along the midline of the sternum for capturing action potential propagation; and

    an externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and respiratory events comprising physiological events detected by the respiratory sensors.
