Patient Care第 6 / 100 题
A pulse oximeter reads 97% on room air for a stable adult. How should the technician interpret this value?
a.Critically low, apply oxygen immediately
b.Abnormally high, remove the sensor
c.Within the normal range of 95-100%
d.Normal only for patients receiving oxygen
解析
A normal oxygen saturation (SpO2) for a healthy adult on room air is 95% to 100%. Readings below 90% generally indicate hypoxemia and require prompt attention. Cold fingers, nail polish, and poor perfusion can produce falsely low readings.
