Abstract
A system for telemetering data from a patient to a monitor permitting direct connection of patient's sensors and transducers to the monitor and permitting telemetering by radio or wire without requiring changes in transducer or monitor design or adjustment or calibration. A telemetering system which presents to the monitor variable resistances identical to the varying resistances produced by the transducers at the patient. A temperature transmission channel wherein a thermistor resistance is digitized for transmission, with the digital data being utilized to generate a resistance at the receiver corresponding to the thermistor resistance. A pressure transmission system providing for transmission of waveform and peak and trough values of the waveform, with the waveform being reconstituted at the receiver and converted to a varying resistance for connection to the monitor, simulating the original pressure transducer resistance.
