The Pulse Oximeter Plethysmographic Waveform Reflects Changes That Occur during the Respiratory Cycle
Many pulse oximetry technologies display a processed and filtered representation of the photoplethysmosgraphic waveform. Each manufacturer uses unique proprietary algorithms to calculate the waveform displayed on the pulse oximeter. Masimo has extracted and processed information from the waveform to create two physiologic indices, perfusion index (PI) and pleth variability index (PVI). PI is ca...

متن کاملPulse oximeter plethysmographic waveform changes in awake, spontaneously breathing, hypovolemic volunteers.
BACKGROUND The primary objective of this study was to determine whether alterations in the pulse oximeter waveform characteristics would track progressive reductions in central blood volume. We also assessed whether changes in the pulse oximeter waveform provide an indication of blood loss in the hemorrhaging patient before changes in standard vital signs. METHODS Pulse oximeter data from fin...

متن کاملA Pulse Oximeter
The objective of this work was to develop a prototype for a pulse oximeter. Given the necessity, in most medical interventions, to monitorize Oxygen saturation in peripheral blood (SpO2) a pulse oximeter is highly necessary in any operating room or intensive care unit. The electronic device was built recurring mostly to Integrated Circuit (IC) and its control was performed via a programmed micr...
