Study Comparing Accuracy of Different Pulse Oximeters with Arterial Oxygen Saturation in Intensive Care Patients

What this Trial Is About

Researchers are studying the accuracy of different pulse oximeters in measuring blood oxygen levels in intensive care patients receiving oxygen therapy. The study compares SpO2 values from four oximeters General Electric-GE, Medtronic, Masimo, and Nonin with the arterial oxygen saturation SaO2 reference obtained from arterial blood gas samples. This research aims to improve oxygen therapy recommendations by addressing variability in oximeter readings. The study involves placing several pulse oximeters on patients a few minutes before collecting arterial blood gases. SpO2 readings from each device are recorded simultaneously with the arterial blood sample. The study includes both pediatric under 18 years and adult 18 years and older populations admitted to intensive care units with artery catheters already installed. Participants will be monitored during arterial blood gas sample collection, where differences between each oximeters SpO2 value and the SaO2 reference are measured. Researchers will assess overestimation, underestimation, and hypoxemia detection capabilities of each device. The study will continue until December 2026, with data helping to refine optimal oxygenation guidelines for intensive care patients.
