Abstract: In one aspect, the invention is a method for processing pulse oxymetry data signals. The method includes recording pulse oxymetry data signals. The pulse oxymetry data signals have a plurality of oxymetry waveforms. The method also includes determining a correlation coefficient between sequential oxymetry waveforms and identifying a valid pulse oxymetry waveform.
Abstract: A portable machine records electrocardiographic signals and oxygen saturation signals in a removable memory device provided by an oxygen saturation sensor attached to a patient and patient lead wires with electrodes attached to the patient.
