Comparing oxygen targets with different oximeters for better oxygen flow management

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the impact of two different oximeters, Nonin and Philips, on oxygen flow rates and oxygenation targets in patients recovering from cardiac surgery. Participants will be assigned to different oximeters and SpO2 targets (90% and 94%) in a randomized manner, with arterial gas samples collected to assess oxygenation levels. The goal is to determine how the choice of oximeter and target saturation affects the required oxygen flow rates. This could lead to more effective oxygen management in postoperative care.

* Patients admitted to postoperative cardiac surgery intensive care unit
* Presence of an arterial catheter Specific for the extubate patient
* Ongoing on conventional oxygen therapy at moderate flow (up to a maximum of 5L/min) with SpO2 between 88 and 100% with the usual oximeter and nasal cannula.
* SpO2 \< 92% ambient air Specific for the intubate patient FiO2 \<= 0.60 with SpO2 between 88 and 100% with usual oximeter SpO2 \< 92% with FiO2 0.21

Exclusion Criteria:
