The normal range of ABG (Arterial Blood Gas) values may vary slightly between different laboratories and healthcare facilities. However, the typical normal range for arterial blood gases is as follows: pH: 7.35 to 7.45 PaO2 (Partial Pressure of Oxygen): 75 to 100 mmHg PaCO2 (Partial Pressure of Carbon Dioxide): 35 to 45 mmHg HCO3- (Bicarbonate): 22 to 26 mEq/L These ranges indicate the normal levels of acidity (pH), oxygen, carbon dioxide, and bicarbonate in the arterial blood, which are essential for maintaining proper respiratory and metabolic functions in the body. Deviations from these normal values can indicate various medical conditions and require appropriate medical intervention.
