Question

Quizplus · Accepted Answer

Forced expiratory technique is based on the theory of equal pressure point (EPP).
Equal pressure point (EPP) is the point in the airways where the pressure is equal to the pleural pressure. Forced expiratory technique produces compression of the airway peripheral to the EPP. A huff from high lung volumes and a huff from low lung volumes will mobilize the secretions from larger airways and peripheral small airways respectively.
The other options are not based on EPP.
Diaphragmatic breathing is quite relaxed.
Thoracic expansion exercises increase lung volume.
Manual hyperinflation is used for patients with an endotracheal tube or a tracheal tube.
