WebbpCO2 (partial pressure of carbon dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood. 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: Webbpoor correlation with P a CO 2 one study in COPDers shows P v CO 2 exceeds P a CO 2 by 5.4, but only unreliably so with 95%i nterval -8.8 to +20.5 mmHg [6] sensitivity for elevated arterial hypercapnea was 100% in this study with P v CO 2 >45; authors suggest that P v CO 2 can be used to screen for hypercapnea
