PHTY205 Lecture Notes - Lecture 11: Diaphragmatic Breathing, Bronchus, Lung Volumes
Document Summary
Define, and discuss the rationale for the use of the following techniques to assist airway clearance, and discuss the modifications that can be made to the techniques: breathing exercises, deep breathing exercises can: Improve cough effectiveness: reopen closed small airways, allow gas to move through airways. Imparts mechanical energy to the airways which has been shown to: ef , change rheology (less sticky) (cid:862)loose(cid:374)(cid:863) secretions, can be applied to a specific area or generally. Shaking: application of a coarse oscillatory and compressive force to the chest wall during expiration (usually deep breathing, may be done, manually (with hands, mechanically (e. g. oscillating vest) Imparts mechanical energy to the airways which has been proposed to.
