Webb1 dec. 2024 · The concept of how the waveform of pulse oximetry relates to a patient’s blood pressure and microcirculation status during resuscitation has been proposed for more than 20 years 15., 16., but to date there have been no rigorous prospective trials of its clinical effectiveness. WebbThe TM-Oxi uses a pulse oximeter and an automatic oscillometric blood pressure device managed by software. The pulse oximeter waveform or photoplethysmograph (PTG) is a simple and noninvasive optical technique that can be used to detect blood volume changes in the microvascular tissue bed. 20 The PTG waveform is comprised of a pulsatile …
