Your body’s organs and tissues need oxygen to function properly. Lack of adequate oxygen can cause damage to vital organs such as the heart and brain. Hypoxemia can be a very dangerous condition if left untreated.
When there is less oxygen in the blood it can cause various problems. Defects such as shortness of breath, cough, persistent headache, rapid heartbeat, confusion, inattention, blue color of the skin, lips and fingernails can occur.
To diagnose oxygen levels, your doctor will perform a physical examination of your body and lungs. You can also check the color of your skin, fingernails or lips. There are also additional tests that can be done to assess your oxygen level and respiration, such as pulse oximetry and arterial blood gas testing.
Every cell in the body needs oxygen to stay alive. Hemoglobin is needed to carry oxygen to the cells. Hemoglobin production requires iron, its constituent, and nutrients such as vitamin B12 and folic acid to form.
Without oxygen, brain cells begin to die in five minutes and heart cells in 30 minutes. Hemoglobin is needed to carry as much oxygen as it needs to survive, wherever it is needed.
