The Effect of Volitional Pursed-lips Breathing — PLB  

COPD Clinical Trial

Official title:
Evaluation of PLB Physiology in COPD - Untersuchung Zur Physiologie Der Lippenbremse Bei COPD

Clinical Trial Summary

Simulation of pursed-lips breathing by defined stenoses in pulmonary function diagnostics to quantify the effect of the pursed-lips breathing

Clinical Trial Description

Since many years it is recommended for COPD patients to reduce the crossdiameter of the lips in order to improve the exhalation by means of so-called pursed-lips breathing (PLB). But the effects have never been studied quantitatively. In this study, the PLB effect is simulated during lung function diagnostics, using different sized resistors inserted into the routine mouthpiece of the flow sensor to resemble the effective airway resistances of a PLB maneuver. This prospective, randomized study includes 20 healthy subjects and 50 COPD patients, who will perform lung function testing with 4 different sized resistors. ;
