Controlled Coughing

It is also important to clear phlegm or mucous from your lungs so that you can decrease the risk of infection. Some patients may have difficulty with this and may need to use a controlled cough technique to do so.

  • Sit down and lean forward.
  • Take a slow deep breath and hold it for three seconds.
  • Cough out twice, using your diaphragm muscle to push upward while you cough.
