What is the PaO2 range for moderate hypoxemia?

• A. 60-79 mmHg
• B. 40-59 mmHg
• C. 30-39 mmHg
• D. 80-100 mmHg

Answer: (B)

The range for moderate hypoxemia is characterized by a partial pressure of oxygen (PaO2) between 40-59 mmHg. This condition indicates that the oxygen levels in the blood are significantly lower than normal, suggesting that the body may be experiencing inadequate oxygenation. The normal range for PaO2 is typically between 75-100 mmHg, and anything below 60 mmHg is considered hypoxemic. Moderate hypoxemia poses risks to various organ systems, as they rely on sufficient oxygen levels for proper function. Therefore, recognizing this range is critical for clinical assessment and determining the need for oxygen therapy or further interventions to stabilize the patient. Understanding these classifications helps healthcare professionals identify the severity of hypoxemia and respond effectively to protect patient health.
