摘要
A pulse oximeter for determining oxygen saturation and pulse rate is disclosed. The pulse rate oximeter comprises a detector which receives waveforms corresponding to two different wavelengths of light from a patient; a first low pass filter and/or ensemble averager; a pulse rate calculator, coupled to an output of said first low pass filter and ensemble averager; a normalizer coupled to said detector for normalizing said waveforms to produce normalized waveforms; a second low pass filter and/or ensemble averager; and an oxygen saturation calculator coupled to an output of said second low pass filter and/or ensemble averager.
