NON INVASIVE CONTINUOUS HEMODYNAMIC MONITORING

Anesthesiologists routinely use monitoring systems capable of measuring both invasive and non-invasive BP, as well as pulsed oxygen saturation (SpO2).

During general anesthesia, the induction period is critical: the use of high-dose anesthetics to induce unconsciousness leads to arterial hypotension. This phenomenon results from a number of interactions, including a drop in blood pressure (BP). The prevention of intraoperative arterial hypotension to maintain normal blood pressure uses vasoactive agents (phenylephrine, ephedrine, noradrenaline) to reduce vital risk and improve postoperative recovery. As a matter of routine, anesthesiologists use monitoring (every 5 min; anesthetic risk management) capable of measuring BP (and the necessary Pmin), invasive or not, as well as pulsed oxygen saturation (SpO2) and respiratory rate.

One of the limitations of monitoring is that it is intermittent, and therefore lags behind the hemodynamic variations instantaneously generated by anesthesia. Combined analysis of the parameters derived from the SpO2 signal (perfusion index (PI) and microt wave height (HPcrot)) and its continuous visualization on the monitor in order to predict the onset of arterial hypotension and treat it early; representation of the vasomotor state of the patient's arterial system in response to the anesthetic drugs administered during induction of general anesthesia.
