What Are the Signs of a Coma?

A coma may be diagnosed during a hospital stay or suspected during an emergency response.

First responders will often describe a persons state of consciousness using the AVPU scale.

The scale can also help healthcare professionals track improvement, decline, or stability.

The scale provides a maximum possible score of 15, which correlates to a mild coma.

The lowest score of 3 indicates a deep coma.

Often, treatment involves medical stabilization to minimize the risk of permanent brain damage.

Medication to help manage any ongoing infections or inflammatory conditions is sometimes necessary.

After recovery from a coma, rehabilitation can help to strengthen breathing muscles and build muscle strength and control.

Many coma survivors will also need speech and swallow therapy.
