May 8, 2024 · The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs.

An arterial blood gas (ABG) test measures the oxygen and carbon dioxide levels in your blood as well your blood's pH balance. The sample is taken from an artery.

pCO2, pCO2, or is the partial pressure of carbon dioxide (CO 2), often used in reference to blood but also used in meteorology, climate science, oceanography, and limnology to describe the fractional …

Sep 18, 2025 · Learn ABG interpretation step by step. Understand pH, CO2, HCO3, compensation, acidosis vs alkalosis, and respiratory vs metabolic disorders.

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 …

Apr 10, 2026 · The partial pressure of carbon dioxide (PaCO2) is a test that measures the movement of CO2 from the lungs to the blood. It's important for COPD.

pCO2, also expressed as paCO2, stands for the partial pressure of CO2 in the arterial bloodstream. Remember, for the purposes of ABG interpretation, the pCO2 is a respiratory acid.
