Indirectly, the pCO2 reflects the exchange of this gas through the lungs to the outside air. Two factors each have a significant impact on the pCO2. The first is … Arterial vs. Venous blood. pCO2 is referred to as the respiratory component in acid-base determination because the lungs control this value. As the CO 2 level increases, the pH level will decrease.

PCO2 normal - 35 to 45 mm Hg Increases above the levels indicated, could possibly mean that the CO2 is building due to hypoventilation or respiratory failure of some kind. Under normal circumstances, the PETCO 2 (the CO 2 recorded at the end of the breath which represents PCO 2 from alveoli which empty last) is lower than PaCO 2 (average of all alveoli) by 2-5 mmHg, in adults.1-8 The (a-ET)PCO 2 gradient is due to the V/Q mismatch in the lungs (alveolar dead space) as a result of temporal, spatial, and alveolar mixing defects.

The pCO 2 is the partial pressure of carbon dioxide (CO 2) in arterial blood.It is also represented as PaCO 2.This measurement indicates the effectiveness of alveolar ventilation, given the diffusing capacity of the gas. In health and at steady state, values for Pv CO 2 and Cv CO 2 (46 mm Hg and 52 ml CO 2/dl, respectively) are modestly higher than for Pa CO 2 and Ca CO 2 (40 mm Hg and 48 ml CO 2/dl, respectively), producing aP(v–a)CO 2 gap of 4–6 mm Hg. Many studies have demonstrated a tight 2019-03-05 Corrected End-Tidal PCO2 Accurately Estimates PaCO2 at Rest and During Exercise in Morbidly Obese Adults. Santiago Lorenzo. Gerald S Zavorsky.

Indirectly, the pCO2 reflects the exchange of this gas through the lungs to the outside air. Two factors each have a significant impact on the pCO2. The first is how rapidly and deeply the individual is breathing: PAO2 is partial pressure of oxygen in alveoli.
