DODD Medication Pass Certification Practice Exam

Normal oxygen levels are typically within which range?

95-100% 88-92% 100-105% 92-96%

Correct Answer:

95-100%

Explanation:

Normal oxygen levels refer to how well hemoglobin is saturated with oxygen, measured as SpO2 with a pulse oximeter. In healthy individuals breathing room air, this saturation is typically between 95% and 100%. Values below 95% suggest hypoxemia and warrant assessment; 88-92% is considered low, not normal for a healthy person. The range 92-96% is near the lower end of normal for some individuals but the widely accepted normal span is 95-100%. Values above 100% aren’t physiologically possible since saturation cannot exceed full saturation of hemoglobin (though measurement error can cause tiny overreads). Therefore, 95-100% is the normal range.
