Comparison of Two SpO2 Targets With Two Different Oximeters - Impact on FiO2 During Nasal High Flow Oxygen Therapy
Sponsor: Laval University
Summary
Several factors can influence oxygenation monitoring and respiratory support through oxygen therapy: the type of oximeter used, skin pigmentation, and the oxygenation target. It is essential to have an accurate measurement of SpO2 in order to optimize the flow of oxygen or FiO2 administered to patients. The question arises as to the impact of these confounding factors on the FiO2 set during high-flow nasal oxygen therapy. The aim of the study is to evaluate the impact of the oxygenation target and the oximeter used on FiO2 in patients receiving high-flow nasal oxygen therapy.
