Cystic Fibrosis Vest
An airway clearing technique (ACT) is an exercise which encourages the movement of mucus out of a cystic fibrosis sufferer’s lungs. Some ACTs, such as tapping the back or deliberate coughing, are easy to perform and require no special equipment. Others, such as the cystic fibrosis vest, are more “high-tech.” The cystic fibrosis vest is a soft, sleeveless garment which is inlaid with air pockets and connected to an electricity supply. It is worn for one or more daily sessions of approximately 20 to 40 minutes. While in use, the vest inflates and deflates very quickly, causing the wearer’s chest to vibrate. These vibrations can break up mucus deposits and move the deposits into the main airways, from where they can be coughed or huffed out of the body.
