As shock deepens, the more vital organs fail. If shock isn't treated, the brain eventually loses its source of oxygen, and within minutes brain damage or even death occurs, Bergus says. In cases of serious injury, heavy bleeding, heart attack or serious infection, be alert for signs of shock. Warning signals include mental confusion, faintness, nausea, and cold, pale or clammy skin. Lay the person down and raise the feet slightly.
Gravity works against blood flow to the brain and upper body.
Loosen any tight clothing. Wrap the person in a blanket to prevent heat loss. Seek immediate medical attention. Because the stomach and kidneys are among the first organs to shut down during shock, avoid giving food and drink if possible, Bergus says. Doctors treat shock by stabilizing blood pressure with medications that increase the heart rate, constrict large blood vessels, or increase the volume of blood the heart pumps.
