what is an abg test vs mean arterial pressure
A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a blood gas analysis or arterial blood gas (ABG) test. Your red blood cells transport oxygen and carbon dioxide throughout your body. These are known as blood gases. As blood passes through your lungs, oxygen flows into the blood while carbon dioxide flows out of the blood into the lungs.
Systemic mean arterial pressure (MAP) is defined as the mean perfusion pressure throughout the cardiac cycle. MAP is sensed by baroreceptors located in the carotid sinuses and the arch of the aorta. These receptors control arterial pressure mainly by adjusting heart rate and arteriolar vessel radius.
