Understanding Blood Oxygen Levels: What You Need to Know
Blood oxygen levels refer to the amount of oxygen carried by red blood cells in the bloodstream, essential for the proper functioning of the body’s organs and tissues. These levels are typically measured by a pulse oximeter, with normal levels ranging from 95% to 100%. Low blood oxygen levels, known as hypoxemia, can lead to symptoms like shortness of breath, confusion, and fatigue, and may signal underlying health issues such as respiratory or heart conditions. Maintaining healthy oxygen levels is crucial for overall well-being and can be supported by good lung and heart health.
