To understand PH, it helps to understand how your heart and lungs work. Your heart has two sides, separated by an inner wall called the septum. Each side of your heart has an upper and lower chamber. The lower right chamber of your heart, the right ventricle (VEN-trih-kul), pumps blood to your pulmonary arteries. The blood then travels to your lungs, where it picks up oxygen. The upper left chamber of your heart, the left atrium (AY-tree-um), receives the oxygen-rich blood from your lungs.
Arterial Blood Oxygen. While a pulse oximeter is the most common device used to determine your blood oxygen level, it is sometimes necessary to analyze blood taken directly from an artery to assess your oxygen level. This measurement is called an arterial blood oxygen. A normal arterial blood oxygen level typically falls between 75 and 100 mmHg. Your blood carbon dioxide level and pH -- a measure of acidity or alkalinity -- are usually measured along with the arterial blood oxygen level.
