Pulse oxygen can be less accurate for a few reasons such as hypothermia, poor perfusion states, and darker pigmented individuals. The software algorithms for SpO2 can also be less accurate with low SpO2 since you would have to place people in hypoxemic conditions to get reliable data.
WebAmong patients with prior cardiopulmonary disease who had PaO2 and PaCO2 values that were not low and a P (A-a)O2 that was normal, 4 of 28 or 14% (95% CI = 4 to 33%) had PE. Other combinations of blood gas levels and the P (A-a)O2 gradient, failed to exclude PE in larger percentages of patients. Web2 days ago · Normal oxygen saturation for healthy adults is usually between 95% and 100%. 3. If you have a chronic health condition that affects your lungs, blood, or circulation, regularly tracking your oxygen saturation is important. An O2 sat level below 95% is not normal. A level under 90% requires emergency care.
