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.
