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.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are admitted to a postoperative cardiac surgery intensive care unit and require conventional oxygen therapy.

Not a fit: Patients who are unable to provide a SpO2 signal with the oximeter or have conditions like methemoglobinemia or are in isolation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve oxygen management strategies, potentially reducing the risk of oxygen toxicity and respiratory failure in postoperative patients.

How similar studies have performed: While there have been studies on oximeter accuracy, this specific comparison of oxygen targets and their impact on flow rates is novel and has not been extensively tested.
