Heart

The heart pumps blood through the lungs then around the body taking oxygen to all the organs. Without oxygen the cells which make up the body will die. Find out how to use first aid to treat heart problems and what you should look out for.

Topics

• Angina - Is a pain in the chest caused by a reduced blood supply to the heart muscle itself.

• Cardiac arrest – This happens when the heart stops pumping effectively leading to collapse, loss of responsiveness and the person ceasing to breathe. This is a medical emergency.

• Heart attack – This happens when there is an obstruction of the blood supply to part of the heart muscle, leading to pain, or if a large part of the muscle is affected, the heart could stop beating effectively (i.e. it may lead to a cardiac arrest). Urgent medical attention is needed in an attempt to improve the blood flow to the muscle.

• Shock – This happens when there is a disruption to the blood supply to part of the brain, leading to a change in function (i.e. inability to speak, use an arm or a leg. If a large part of the brain is affected the person may lose responsiveness or have a seizure). Urgent medical attention is needed in an attempt to improve blood flow to the brain.
