What Is Waveform Pulse Oximeter?
What Is Waveform Pulse Oximeter? The pulse oximeter waveform (POW) is derived from variation in intensity of transmitted light through tissues. It may be used to provide a non-invasive surrogate for the intra-arterial waveform, and represents an accessible measure of cardiovascular status. What is a plethysmographic waveform? The plethysmographic waveform variation (SPVplet) was measured as
