During the Indifferent Stage of hypoxia, what is the typical oxygen saturation range?

• A. 98-90%
• B. 89-90%
• C. 79-70%
• D. 69-60%

Answer: (A)

During the Indifferent Stage, oxygen saturation stays near normal because the body is just starting to feel less oxygen but can still compensate. In practical terms, SpO2 is typically around 90–98%. This range reflects mild hypoxemia where symptoms are subtle or absent, giving you a window to recognize and respond before more serious impairment occurs. Ranges lower than this (significantly under 90%) indicate progression to more severe stages of hypoxia, where cognitive and physical performance deteriorate and urgent action is needed.
