ABSTRACT:
Apparatus and method for the monitoring of physiological parameters of a patient through the use of optical systems which do not require direct physical contact with the patient. The method and apparatus relate primarily to pulse oximetry for monitoring of pulse rate and arterial blood oxygen saturation. However, the apparatus and method of this invention are applicable to any form of optical detection of the physiological parameters in which light of any wavelength, visible or invisible, is directed from a remote instrument into a patient at a first imaging site, and subsequently collected at a second site spaced from the first site.
