Hypoxia is low levels of oxygen in your body tissues, causing confusion, bluish skin and changes in breathing. It’s treatable but can be life-threatening.

Hypoxia differs from hypoxemia and anoxemia, in that hypoxia refers to a state in which oxygen present in a tissue or the whole body is insufficient, whereas hypoxemia and anoxemia refer specifically to states that have low or no oxygen in the blood. [3]

Hypoxia occurs when your body's tissues do not get enough oxygen, which can lead to severe complications. You may develop symptoms like shortness of breath, confusion, and vision changes.

Learn what hypoxia is, its causes, mechanisms, symptoms, and treatment strategies for improving tissue oxygenation and patient outcomes.

When your body doesn't have enough oxygen, you could get hypoxemia or hypoxia. These are dangerous conditions.

Hypoxia, in biology, condition in which tissues of the body are starved of oxygen. Diseases of the blood, the heart and circulation, and the lungs may all produce some form of hypoxia. In its extreme form, where oxygen is entirely absent, the condition is called anoxia.

This detailed, humanized guide walks you through what hypoxia is, its causes (general and post-operative), how it presents clinically, and how to manage it effectively.

Hypoxia, a fundamental stimulus in biology and medicine, changes expression of about 400+ genes, depending on the cell type and nature of the microarray, which collectively serve to allow the cell and tissue in which it resides to adapt to the low oxygen environment.

Hypoxia and hypoxemia are conditions in which there is insufficient blood in the arteries. Learn about the types, causes, symptoms, treatment, complications, and prevention.

Diseases that result in acute or chronic respiratory distress can result in hypoxia. These diseases can be acute in onset (such as obstruction by inhaling something or a pulmonary embolus) or chronic (such as chronic obstructive pulmonary disease).
