ABSTRACT

The pulse oximeter, a common device in different hospital areas, especially in critical areas, is used most of the time to assess the patient's respiratory status; however, current evidence shows that this device can provide us with valuable information on hemodynamic behavior, the response of the autonomic nervous system, and the therapy given to critically ill patients. It is for this reason that knowing the fundamentals of oximetry, values beyond oxygenation such as the plethysmographic waveform and the perfusion index results in an important amount of information for decision making and the response to the treatments performed.
