Ace the 2026 Certified Transport Registered Nurse Exam – Soar to Success in Your Nursing Career!

The normal values for arterial oxygen saturation (SO2) typically range from 95% to 99%. This range indicates that a healthy person's hemoglobin is effectively saturated with oxygen, allowing for adequate oxygen transport throughout the body. When SO2 levels fall below this range, it may indicate hypoxia or inadequate oxygenation of the blood, which can be a critical condition requiring intervention.

Understanding these values is essential for transport registered nurses, as monitoring blood oxygen levels is a key aspect of patient care, particularly during transport where patients might be at a higher risk for complications. Maintaining SO2 within this normal range is crucial for ensuring optimal organ function and overall health.
