Sheba Medical Center
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.

Condition Intervention
Cystic Fibrosis Device: Tri-Gym

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Immediate Effect of Resistive Expiration Via "Volumetric Incentive Spirometer" on Lung Function in Patients With Cystic Fibrosis.

Primary Outcome Measures:
  • lung function [ Time Frame: fifteen minutes after intervention ]
    Forced expiratory maneuvers were measured before and 15 minutes after intervention.

Enrollment: 40
Study Start Date: December 2008
Study Completion Date: July 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: lung function Device: Tri-Gym
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.
Other Name: incentive spirometer
