Abstract
A pulse oximeter includes a capacitive d.c. blocking element to separate the time varying red and infra-red components of a light source transmitted through or reflected form the blood from the composite light signals. The magnitudes of the signal amplitudes are then digitized and converted for use as independent variables applied to a ROM based look-up table to determine blood oxygen saturation.
