<unk>  is treatment that uses a number of<unk><unk>  techniques to clear the respiratory<unk> s of mucus and other secretions. Several respiratory diseases cause the normal mucociliary<unk>  mechanism to become impaired resulting in a build-up of mucus which obstructs breathing, and also affects the cough reflex. Mucus build-up can also cause infection, and inflammation, and repeated infections can result in damage to the<unk> s, and the lung tissue. All<unk>  involves the techniques of coughing, or huffing that need to be used in conjunction with another<unk><unk>  technique. Respiratory therapists make recommendations and give guidance for appropriate<unk> es. They also give instruction in the use of various<unk><unk>  techniques.
