A) PaO2 greater than 90 mm Hg
B) SpO2 greater than 60%
C) PaO2 greater than 60 mm Hg
D) SpO2 greater than 95%
Arterial Blood Gas
A diagnostic test that measures the levels of oxygen, carbon dioxide, and acidity (pH) in arterial blood, used to assess lung function and gas exchange.
Oxygen Saturation
A measure of the amount of oxygen carried by the hemoglobin in the blood relative to its maximum capacity, typically expressed as a percentage.
Pulse Oximetry
A non-invasive method of monitoring an individual's oxygen saturation level in the blood, often using a clip-like device on the finger.
