Apparatus for monitoring from a single station a physiological condition of each of a plurality of remotely located patients. A radio transmitter at the station generates sequentially a plurality of tone signals, one for each patient and each of a different frequency, on a common carrier. A radio receiver with each patient has a band pass corresponding to a particular one of the tone signals. Each receiver when addressed activates a radio transmitter with the patient for transmitting to a single receiver at the station a coded signal indicative of the physiological state of the patient, derived from signal generating means operatively connected to the patient. The signals received at the station are sequentially routed, decoded, and applied to suitable indicators.
