ClinConnect Summary

This clinical trial is studying how different types of oxygen monitors (called oximeters) affect the amount of oxygen needed for patients who have had heart surgery and are recovering in the intensive care unit. The researchers want to see how well these oximeters measure oxygen levels in the blood and how that might change the amount of oxygen patients receive. They found that some oximeters are better at detecting low oxygen levels, while others may give inaccurate readings, which can lead to different amounts of oxygen being prescribed.

To be eligible for this study, participants need to be at least 18 years old, currently in the cardiac surgery intensive care unit, and receiving oxygen therapy through a nasal cannula. They should also have a specific level of oxygen in their blood. Participants will not be allowed to join if they have certain conditions or are using other types of breathing support. Those who participate can expect to help improve understanding of how to provide better oxygen care for patients in similar situations. It's important to note that most of the participants in this study will have light skin, which may affect the results.
