2023年5月4日 · What Is Partial Pressure of Carbon Dioxide (PaCO2)? Evaluates Impact of CO2 on Obstructive Lung Disease. The partial pressure of carbon dioxide (PaCO2) is one of several measures calculated by an arterial blood gases (ABG) test. This is often performed on people with lung diseases, neuromuscular diseases, and other illnesses.

2024年5月8日 · It is a measurement of carbon dioxide (CO2) in the blood and is affected by CO2 removal in the lungs. A higher PaCO2 level indicates acidosis while a lower PaCO2 level indicates alkalosis. A blood gas test measures the amount of oxygen and carbon dioxide in the blood.

2022年9月26日 · 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. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg or 4.7 to 6.0 kPa.

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 pressure of CO 2 as a function of its concentration in gas or dissolved phases.

PaO 2 indicates gas exchange in the lungs, and it determines the status of arterial blood oxygenation. A low PaO 2 indicates hypoxemia (low oxygen in the blood), which may be caused by hypoventilation or a mismatch between ventilation and perfusion.

2025年3月2日 · PaCO2 (Partial Pressure of Carbon Dioxide): Indicates the effectiveness of the respiratory system in eliminating carbon dioxide. PaO2 (Partial Pressure of Oxygen): Represents the ability of the respiratory system to supply oxygen to the arterial blood. HCO3- (Bicarbonate): Provides insight into the metabolic component of acid-base balance.

Carbon dioxide is created as a waste product of normal cellular metabolism. The amount of pressure exerted by carbon dioxide dissolved in the blood is known as the partial pressure of carbon dioxide, or pCO2, according to Eastern Kentucky University. Respiration is controlled by a section of the brain called the medulla.
