Extra mucus can collect in your lungs and make you sick. There are a number of reasons this may occur, but whatever the reason, it is vital to clear this mucus regularly.You and your doctor may have selected one or more ways to clear the mucus from your lungs.
It could be chest physical therapy (chest PT) with postural drainage, use of a flutter valve, use of a pep valve or an inflatable electric vest. The respiratory therapist will likely teach you additional clearance methods including a deep or "huff" cough. Whatever method of mucus clearance you have discussed with your doctor, please remember that every time you cough out infected mucus, there is that much less in your lungs to do damage and that much less for the antibiotics to overcome.
