Chest physiotherapy  is the treatments generally performed by physical therapists and respiratory therapists, whereby breathing is improved by the indirect removal of mucus from the breathing passages of a patient.

Techniques include clapping or percussion: the therapist lightly claps the patient's chest, back, and area under the arms. These include, but are not limited to, the use of "flutter" or oscillating positive pressure devices, PEP masks or devices (positive expiratory pressure) as well as specific exercise regimes. The exercises prescribed can include specific respiratory exercises e.g. autogenic drainage, as well as general cardiovascular exercises that assist the body to remove sputum and improve the efficiency of oxygen uptake in muscles.
