Final answer:
A patient is not hypoxemic if the pulse oximetry reading is 95 percent or higher, which is considered within the normal range for oxygen saturation in hemoglobin.
Step-by-step explanation:
A patient is not considered hypoxemic if his pulse oximetry reading is 95 percent or higher. Pulse oximetry is a non-invasive method that measures the percent saturation of oxygen in hemoglobin. It does this by passing two wavelengths of light through the finger and uses a photodetector to measure the differential absorption of light by oxygenated versus partially oxygenated hemoglobin. Readings between 95-100 percent are considered normal, whereas lower readings signify hypoxemia, indicating low blood oxygen levels.
