What is the normal range for PaO2 in mmHg?

• A. 40-59 mmHg
• B. 60-79 mmHg
• C. 80-100 mmHg
• D. 100-120 mmHg

Answer: (C)

The normal range for arterial oxygen partial pressure (PaO2) in healthy adults is typically between 80 and 100 mmHg. This range reflects the levels of oxygen dissolved in the blood and indicates adequate oxygenation of the blood as it passes through the lungs. Maintaining PaO2 within this normal range is crucial for effective oxygen delivery to tissues throughout the body. Values below the normal range may indicate hypoxemia, which can result from various conditions such as respiratory diseases or impaired gas exchange, while values above might suggest hyperoxia, which could also have adverse effects. Understanding the normal values for PaO2 is important in clinical practice, as it aids in the assessment of a patient's respiratory function and overall oxygenation status.
