The low oxygen saturation, also known as hypoxia, refers to the lack of oxygen in the body. Hypoxia can be classified as generalized hypoxia, which occurs when the body rejects, or tissue hypoxia caused by the shortage of oxygen in a specific section or body region. Results from insufficient oxygen supply to the body which leads to a drop in the partial pressure of oxygen in arterial blood. The normal oxygen saturation varies between 96% to 100%, while a smaller percentage of 90% can cause life-threatening complications.

Cyanosis

Cyanosis is attributed to hemoglobin unoxygenated within the capillaries in excess of 5 g / dl carrying have beds in the nail, mucous membrane, skin pigment and sometimes in the nose, ears and feet turned blue . The blue pigment is easily seen when oxygen levels in the body fall below 90%. Cyanosis can also be attributed to the presence of abnormally high methemoglobin (metHb) that prevents metHb binds with oxygen, decreasing oxygen saturation.

cognitive distortion

When the availability of oxygen reaching the brain becomes blocked, it decreases the level of awareness and attention and leads to uncoordinated movement. Further reducing the availability of oxygen in the brain can cause cerebral hypoxia can result in a coma, which is a complete loss of consciousness. Other symptoms of cerebral hypoxia as the lack of response to light and bad breath can arise from severe reduction in oxygen saturation in the brain.

gastrointestinal disorders

When the body experiences low oxygen saturation, the blood is directed to the vital organs such as the heart, brain and lungs, leading to decreased digestion and absorption of food in the gastrointestinal tract, compromising its function Basic. Disturbance of the digestive system as a result of hypoxia will feel nauseous and suffer from loss of appetite. Slow absorption and distribution of food in the gastrointestinal tract as a result of hypoxia may cause vomiting.

Fast breathing

When the body experiences hypoxia, automatically it comes with several mechanisms to resolve the situation. The depth and breathing rate increases to help deliver more oxygen to the lungs. The pulse increases as a result of pumping blood faster heart in order to increase the level of oxygen to tissues supplied. All these adaptations are manifested in rapid breathing as the body tries to compensate for the oxygen deficiency in the system. The body can accommodate these adjustments only for a limited time, requiring supplemental oxygen.

Treatment of hypoxia

Hypoxia usually treated giving supplemental oxygen patients, commonly known as oxygen therapy. People suffering from hypoxia are hospitalized and placed in a mechanical to assist breathing ventilation. Vital signs Blood pressure, respiratory rate, temperature and pulse are constantly monitored. Cold blankets can help curb the activity of brain cells, reducing the demand for additional oxygen. However, it treats the underlying cause of hypoxia to prevent future cases.
