Hypoxia is a medical condition in which some or all the tissues of the body do not receive a sufficient supply of oxygen from the blood. Various types of heart disease, unhealthy or afflicted blood, impaired circulation, or diseases affecting the lungs may all produce some form of hypoxia. Since oxygen is required throughout the body to sustain health, hypoxia can have serious consequences and requires immediate medical treatment.
The symptoms of hypoxia include increased heart rate, changes in blood pressure, rapid breathing, shortness of breath, and a blue or ashen tint to the flesh due to the lack of oxygen. The condition can also affect the nervous system, and some people develop confusion and slurred speech.
