Drowning occurs when normal air exchange in the lungs is prevented. This can happen when a person's nose and mouth are under the surface of a liquid, or when a person's face comes in contact liquid.
Drowning is caused by breathing problems because of liquid, such as water. At first, the person will hold his or her breath. Eventually, the person will no longer be able to hold it. The liquid will flow into the lungs. This liquid will not allow the normal gas exchange in the lungs to happen.

CPR is done to provide oxygen rich air to the vital organs of the body. This may involve giving rescue breaths or doing chest compressions. In all unconscious people and those who have been diving, the head and neck should be supported in case of injuries to the spine.
This is done if the body's temperature dropped after being in cold water. Warming treatments are done slowly to avoid further injury to the body.
A narrow tube is placed into the large airways of the lungs to allow mechanical ventilation.
This is a narrow, flexible, plastic tube that is placed through the nose into the stomach. People with drowning injuries may have swallowed a lot of water.
