O75: Other complications of labour and delivery, not elsewhere classified

O75.1: Shock during or following labour and delivery

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.

A circulatory shock involves having major problems with the circulatory system. As a result, some areas of the body no longer get a sufficient supply of blood.

A circulatory shock can produce a variety of symptoms. The blood pressure may be low and the heart may beat more quickly than usual. Insufficient blood no longer being able to get to the brain may cause you to lose consciousness. Certain organs may no longer work properly. This can affect the kidneys or lungs, for example. A circulatory shock can be life-threatening.
