A common cause of low arterial oxygen levels, known as hypoxemia, can be attributed to various factors such as lung related issue.
what is causing the patients low arterial oxygen
Lung related issue: Sicknesses like pneumonia, COPD, asthma, or pulmonary embolism can make it hard for the lungs to exchange oxygen and carbon dioxide, which leads to low oxygen levels in the blood.
Heart problems: Some conditions, like heart failure or birth defects, can make it hard for the heart to pump oxygenated blood to the body.
Anemia is when there aren't enough red blood cells or hemoglobin in the blood, which makes it harder for the blood to carry oxygen. This can make the oxygen levels in the blood lower than normal.
In places with high altitude, the air pressure is lower, which reduces the amount of oxygen in the blood. Breathing in some dangerous gases or chemicals can also make your body have less oxygen.
