Short-Term Effect of Intermittent Intrapulmonary Deflation on Air Trapping in Patients With COPD.

ABSTRACT:

Background

Intermittent intrapulmonary deflation is an airway clearance technique that generates negative pressure during expiratory phases. This technology is intended to reduce air trapping by delaying the onset of air-flow limitation during exhalation. The objective of this study was to compare the short-term effect of intermittent intrapulmonary deflation versus positive expiratory pressure (PEP) therapy on trapped gas volume and vital capacity (VC) in patients with COPD.

Methods

We designed a randomized crossover study in which the participants with COPD received a 20-min session of both intermittent intrapulmonary deflation and PEP therapy on separate days and in random order. Lung volumes were measured via body plethysmography and helium dilution techniques, and spiro
