Feb 18, 2022 · An arterial blood gas (ABG) test is a blood test that requires a sample from an artery in your body to measure the levels of oxygen and carbon dioxide in your blood.

May 8, 2024 · Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa. The PaCO2 level is the respiratory component of the ABG. It is a …

Abnormal pCO2 venous levels indicate various health conditions affecting the respiratory and metabolic systems. Elevated pCO2, or hypercapnia, is linked to conditions impairing the lungs’ ability to expel …

Dec 10, 2025 · The PaCO2 test measures carbon dioxide levels in the blood to evaluate lung function. High CO2 levels can lead to respiratory acidosis, especially in people with COPD.

May 17, 2024 · VCU Health Pathology Blood Gas Laboratory Reference Interval and Critical Results Table

PCO2 is a respiratory acid with a normal range between 35-45. If the number increases, the result is respiratory acidosis, and if it decreases, it is respiratory alkalosis. HCO3, or bicarbonate, is a …

Carbon dioxide (CO 2) is an acidic gas; the amount of CO 2 in blood is largely controlled by the rate and depth of breathing or ventilation. p CO 2 is the partial pressure of CO 2 in blood.

Feb 7, 2025 · The normal ranges for arterial partial pressure of carbon dioxide (PCO2) and partial pressure of oxygen (PO2) are 4.6–6.1 kPa (34–46 mm Hg) and 10.0-13.3 kPa (75-100 mm Hg), …

Jan 23, 2026 · The PCO2 reading is an independent measure that helps assess the efficiency of lung ventilation. The normal range for the partial pressure of arterial carbon dioxide (\ (\text {PaCO}_2\)) …

Jul 29, 2023 · This comprehensive article aims to provide a thorough understanding of PCO2, including its significance, factors affecting PCO2 levels, measurement methods, and clinical implications.
