The Cough—Its Effectiveness Depends on You

Abstract

Normal coughing is a protective device to keep debris out of the airways or to rid them of it. But abnormal coughing or the absence of coughing may hinder health or fail to help provide it. Many patients need to be taught why to cough, when to cough, and how to cough. They need instruction about positioning, breathing control, and conditioning of muscles. Cardiac patients must cough without undue energy expenditure. Chronic lung disease patients usually require hydration to enhance the cough. Ventilator-supported patients should be in the assist mode if possible, to enhance muscle tone for coughing during and after weaning. Surgical patients require preoperative instruction in breathing and coughing, and postoperative coughing should be timed to coincide with pain medication. Cough-produced sputum should be examined regularly to assess disease or health. Teaching coughing seems mundane and takes time, but it can save even more complications' time and money.
