A patient with ineffective airway clearance is being discharged home. Which home therapy will help the patient loosen and expectorate secretions?
a. Capnography
b. Water-seal chest drainage
c. Transtracheal oxygenation
d. Vibratory positive expiratory pressure device
ANS: D
An alternative to chest physiotherapy for promoting airway clearance is a small hand-held device called a vibratory positive expiratory pressure (PEP) device. It has a heavy steel ball that bounces and causes vibrations in the chest when the patient blows into it. Capnography measures exhaled carbon dioxide and is not therapeutic. Water-seal chest drainage is used for pneumothorax, and transtracheal oxygen is an oxygen delivery system.
