  1. Severe Acute Respiratory Syndrome (SARS) - Topic Overview

    Postural drainage and chest percussion are often used together to help loosen and remove mucus from the lungs. These airway clearance techniques help people who have a spinal cord injury, cystic fibrosis, or another condition that makes it hard for mucus to drain from the lungs. When mucus collects in your lungs, it increases your risk for lung infections.Postural drainage uses gravity to help drain mucus into the mouth by placing the body in specific positions. Each position drains different areas (lobes) of the lung. The mucus can then be spit or coughed out.Chest percussion (chest physiotherapy) uses clapping of the chest with a cupped hand to vibrate the airways in the lungs. This vibration moves the mucus from smaller airways into larger ones where it can be coughed up. Chest percussion is done with the help of a partner, special electronic devices designed to vibrate the chest, or other instruments that a person can use to vibrate the chest safely.A doctor or respiratory

This test is not used very often because it can be difficult to do and because it is not available in many places.

  10. Severe Acute Respiratory Syndrome (SARS) - Topic Overview

    Cystic fibrosis often affects the pancreas and digestive system because the mucus in these areas becomes thick and sticky. If this occurs, the mucus blocks normal digestive function as well as harbors infection.The digestive system is responsible for breaking down food, absorbing nutrients from the food, and ridding the body of waste products. The pancreas is an organ that is located in the upper abdomen, behind the stomach and close to the spine. It produces digestive enzymes, which travel to the intestines and break down (digest) food so that nutrients can be absorbed by the body. Cystic fibrosis and digestionIn cystic fibrosis, mucus clogs the pancreas, and digestive enzymes are not able to get to the intestine. So food is not properly digested, particularly fats and proteins. A related symptom is large, greasy, smelly stools. Lack of nutrition prevents normal growth and development in babies and children. Unhealthy weight loss and difficulty gaining or maintaining weight are
