Removing mucus from the lungs is essential to help avoid infection and coughing is one of the best ways to achieve this. The forced coughing technique is best done sitting in a chair with a straight back and feet on the floor. It begins by breathing in as deeply as possible to expand the diaphragm. The patient will then need to hold their breath for a count of three and then open their mouths and cough hard twice. Any mucus that comes up should be discarded into a tissue. The technique should be repeated until the patient feels they have removed all excess mucus from their airways.
