What Is Hypoxemia

When there is lack of oxygen in the tissues of the body, the condition is termed as Hypoxemia. It may affect the entire body or only specific areas like the brain. Wherever it occurs or whenever it occurs, it is very dangerous. Lack of oxygen to any part of the body means, that specific part cannot function. Oxygen is essential for the body as a whole. There are several reasons leading to this affliction. You inhale air which includes oxygen and many problems may arise between the time you inhale the air and the time oxygen reaches the cells.

Even people in normal health may suffer from Hypoxemia. People in high altitudes will find the air very thin, with the oxygen available being very much less that what is required for the body’s normal functioning. Similarly people having the affliction of asthma will have less that the required amount of oxygen in the blood leading to problems in the lungs or the cells conveying the oxygen to different parts of the body. Workers in chemical factories or labs may get affected due to the air inhaled by them containing gases at uncontrollable levels.

Normal symptoms of Hypoxemia are breathlessness or fast breathing. Other symptoms are nausea, dizziness, euphoria, confusion etc; when any of these symptoms appear without any visible or apparent causes it requires medical attention which involves testing of the blood. The test result will provide information about the oxygen present in the blood, dissolved in it. Lack of oxygen in the system may lead to strokes because oxygen supplied to the brain is severely affected because of the collapse of the lungs.     

It is possible that in some cases proper diagnoses with determining the cause for the attack may not be possible. Due to problems in the body mostly physiological even if the body gets a lot of oxygen it may not be possible to use it effectively. If red blood cells are affected they will not be able to convey the oxygen that is required. In such cases it becomes a challenge for the physicians. Pinpointing the cause for disease is essential and unless it is done proper and effective treatment cannot be given.

General causes for Hypoxemia are the health condition of the person concerned. People suffering from asthma, lung cancer, allergy, blood clots etc; are all susceptible to get affected by the disease. Similar is the case with people working in high altitudes. The problem is that the patient may not be able to identify the condition. The symptoms in many cases may be very subtle like giddiness.
