ABG Interpretation Questions and Answers 100% Pass Which blood gas measurement assesses the efficiency of a patient's lung ventilation? PaCO2 Which blood gas measurement gauges the extent of tissue oxygenation? PvO2: Typically ranges between 35 - 45 mmHg. A decreased PvO2 indicates insufficient oxygenation of tissues, often due to reduced cardiac output. When cardiac output declines, blood flow to tissues slows, while tissue oxygen uptake remains unchanged. Consequently, some tissue...
