Learn about the causes, symptoms, and treatment options for Anoxia, a condition characterized by a lack of oxygen to the body's tissues. In general, the known types of anoxia will correspond to the main cause responsible for the reduction in the oxygen supply to the brain. In this way, we can talk about four different types: Anoxic Anoxia:usually happens when an inadequate amount of oxygen is taken in. An Anemic Anoxia: in this case, oxygen supply to the brain can be affected by a lower capacity to oxygenate hemoglobin. Ischemic Anoxia (or Hypoxia):normally associated with an inadequate supply of oxygen to brain tissue due to ... Anoxia occurs when the body or parts of the body do not receive oxygen—it's a life-threatening condition. The loss of oxygen can occur due to respiratory failure, cardiac arrest, traumatic brain injury, difficult delivery (affecting newborns), or other medical conditions. Anoxia occurs when a person's body or brain stops getting oxygen. Learn more about the causes, symptoms, and types in this article.
