Pco2

Symbol for partial pressure (tension) of carbon dioxide. See: partial pressure.

pCO2

Symbol for the negative decadic logarithm of the CO2 concentration.

Pco2

carbon dioxide partial pressure; also written PCO2, pCO2, or p CO2.

carbon dioxide tension (PCO2)

the partial pressure of carbon dioxide, a measure of the relative concentration of the gas in air or in a fluid, such as plasma. It is expressed quantitatively in millimeters of mercury (mm Hg). Alveolar PCO2 directly reflects pulmonary gas exchange in relation to blood flow: alveolar PCO2 usually decreases as the respiration rate increases. Normal values for arterial and alveolar PCO2 are between 35 and 45 mm Hg. Higher levels occur in conditions of slow blood flow and respiration. Below-normal values are caused by hyperventilation and lead to respiratory alkalosis. Also called carbon dioxide pressure. See also carbon dioxide, hypercapnia, hyperventilation, hypoventilation.

PCO2

Partial pressure of CO2 in blood, expressed in kilopascals

PCO2

, pCO2
Abbreviation for partial pressure (tension) of carbon dioxide.
See: partial pressure

PCO2

The concentration of carbon dioxide in the blood. This is a sensitive indication of the efficiency or level of ventilation of the lungs. Hyperventilation causes a drop in PCO2; underventilation causes a rise.

PCO2

partial pressure of carbon dioxide

Pco2

carbon dioxide partial pressure or tension; also written PCO2, pCO2 and pCO2. See respiration and blood gas analysis.
