The Use of Visual Feedback in Airway Clearance
Cystic Fibrosis (CF) patients perform airway clearance incorporating various breathing strategies, to clear secretions from their lungs. Hand held devices may aid mucus expectoration, and also motivate the patient to manage by themselves. Our aims was to study if resistive expiration through "volumetric incentive spirometer" (VISex) can improve lung function in the short term in Cystic Fibrosis (CF) patients.

Primary Purpose: Treatment
|Official Title:||The Immediate Effect of Resistive Expiration Via "Volumetric Incentive Spirometer" on Lung Function in Patients With Cystic Fibrosis.|
- lung function [ Time Frame: fifteen minutes after intervention ] [ Designated as safety issue: No ]Forced expiratory maneuvers were measured before and 15 minutes after intervention.
|Study Start Date:||December 2008|
|Study Completion Date:||July 2009|
|Primary Completion Date:||June 2009 (Final data collection date for primary outcome measure)|
|Experimental: lung function||
40 CF patients performed airway clearance using the VISex, by exhaling against chosen resistance being motivated by visual feedback of raising colored balls. The level of resistance was set to cause longest expiration/volume, until mucus was transported from the peripheral to the central airways, to be expectorated by the subsequent cough.
