Your child may need a tube in the nose or throat to help him or her breathe. Oxygen will be given through the tube. It will be left in for about 36 hours and taken out when breathing is easier. It is placed on the ear, finger, or toe and is connected to a machine that measures the oxygen in your child's blood. A stethoscope is used to listen to the heart and lungs.
Blood pressure is taken by wrapping a cuff around the arm.
The patches on your child's chest are hooked up to a TV-type screen. This screen shows a tracing of each heartbeat. Your child's heart will be watched for signs of injury or damage that could be related to the illness. It will help your doctor decide on treatment. It is done to check on the breathing problems.
