Self-Contained Personal Air Flow Sensing Monitor

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

• a disposable extended wear electrode patch comprising:
• a flexible backing formed of an elongated strip of stretchable material with a narrow longitudinal midsection and, on each end, a contact surface at least partially coated with an adhesive dressing provided as a crimp relief;
• a pair of electrocardiographic electrodes conductively exposed on the contact surface of each end of the elongated strip;
• a non-conductive receptacle adhered to an outward-facing surface of the elongated strip and comprising a plurality of electrical pads;
• and
• a flexible circuit affixed on each end of the elongated strip as a strain relief and comprising a pair of circuit traces electrically coupled to the pair of the electrocardiographic electrodes and a pair of the electrical pads, at least one of the circuit traces adapted to extend along the narrow longitudinal midsection to serve as the strain relief;
• and
• a reusable electrocardiography monitor having a sealed housing adapted to be removably secured into the non-conductive receptacle and comprising:
• a micro-controller operable to execute under micro programmable control and electrically interfaced to an electrocardiographic front end circuit that is operable to sense electrocardiographic signals through the electrocardiographic electrodes via the pair of the electrical pads;
• an air flow sensor operable to sense air flow events, the air flow sensor electrically interfaced with the micro-controller over an expansion bus operatively interconnected to the micro-controller;
• and
• a flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and the air flow events.
