1. An optical patient monitoring apparatus, comprising:

  • a transducer for detecting a physiological function, said transducer being designed for placement on a patient to be monitored, and said transducer providing an output signal indicative of said physiological function;

    a modulator for modulating a carrier by said output signal;

    a waterproof optical source associated with said modulator for emitting an optical signal which corresponds to said modulated carrier;

    a photodetector for receiving said optical signal, said photodetector being adapted to receive said optical signal after said optical signal passes through a water-air boundary; and

    a monitoring circuit coupled to receive the modulated carrier from said photodetector.
