ClinConnect Summary

The Oxygap2 Study is a clinical trial that is looking at how well different types of oximeters measure oxygen levels in patients who are in the Intensive Care Unit (ICU) and receiving oxygen therapy. Oximeters are devices that help monitor how much oxygen is in the blood. The study aims to compare the readings from various oximeters—such as those made by General Electric, Medtronic, Masimo, and Nonin—with a more precise method called arterial gas measurement. This is important because having accurate readings can help doctors make better decisions about how to manage oxygen levels, ensuring patients receive the right amount of oxygen and avoid complications.

To participate in this study, you must be at least 18 years old and admitted to the ICU with an artery catheter already in place. Unfortunately, people with certain conditions, such as very low blood oxygen levels or specific infections, may not be eligible. If you join the study, you'll help researchers gather important information that could lead to improved recommendations for oxygen therapy in the future. This is a great opportunity to contribute to advancements in patient care while receiving close monitoring during your treatment.
