Apparatus and method for remote monitoring of physiological parameters.

Apparatus and method are disclosed for monitoring selected physiological parameters of a subject, such as respiration and/or ECG information, and alerting a care giver at a remote location when an irregularity is recognized. The apparatus includes a sensor or sensors, a dual frequency, asynchronous transmitter unit for transmitting plural signals indicative of the sensed information, a local receiver/transmitter unit, and a remote receiver. The physiological parameters being monitored are sensed and processed to provide signals which are provided to a pair of transmitters. Transmission is selectively enabled at each transmitter, the first transmitting at a first frequency a signal indicative of real time monitored events and the second, under normal circumstances, transmitting, periodically, at a second frequency a signal indicative of monitored event count and updated subject status. When received at the local receiver, both signals are processed and retransmitted to the remote receiver where, if irregularity is indicated, the care giver is alerted.
