Design outcomes

Primary

Measure	Time frame
?Use of ORI as a guide for alveolar recruitment level (Positive End Expiratory Pressure, PEEP adjustments) mmHg and the titration of adequate fractional inspired oxygen. (FiO2)	—

Secondary

Measure	Time frame
? Relation between ORI and arterial oxygen tension in blood (PaO2) mmHg ? To investigate the beneficial role of ORI in preventing unintended hyperoxia ? Comparing ORI to regular pulse oximetry oxygen saturation (%) as an early alarm for hypoxia particularly during induction of anesthesia and recovery in Post Anesthesia Care Unit (PACU).	—
