T66-T78: Other and unspecified effects of external causes
T71: Asphyxiation
There are a variety of reasons why there may be a life-threatening shortage of oxygen. For example, the oxygen level in the environment might be too low. But it may also be that you are unable to breathe properly. This is the case when the airways are blocked or constricted, for example. A life-threatening shortage of oxygen may also occur with certain illnesses or poisonings. For example, certain poisonings can prevent enough oxygen getting into the blood.
A life-threatening shortage of oxygen can cause a circulatory collapse. The heart pumps blood through the blood vessels to the body. The blood then flows back to the heart through other blood vessels. Together, the heart and the blood vessels form the blood circulatory system. Blood supplies oxygen and nutrients to the tissue in the body. With a circulatory collapse, the blood is no longer pumped around the body. When a circulatory collapse is caused by a lack of oxygen, it is called asphyxiation.
