A pulse oximeter and method of determining the oxygen saturation level of a patient's blood wherein a heartbeat related signal is used, as a reference to guide the averaging of optical pulse waveforms. The oximeter and method assign different weighting to different optical pulses based upon the amplitude of new pulse waveforms and the degree of similarity between it and the preceding waveform. A composite, averaged pulse waveform is then used in computing oxygen saturation level.
