Análise da mecânica respiratória em tempo real: Efeito das alterações no padrão ventilatório em normais

Abstract

Several respiratory diseases, as well as surgical procedures, introduce pathological alterations in the thoracoabdominal motion. The aim of the present study is to investigate alterations in respiratory mechanics of healthy people, under different breathing patterns by using a real-time implementation of the Forced Oscillation Technique. Twenty individuals were submitted to a protocol in which they performed different breathing patterns for a period of 18 seconds. The results suggest that alterations in the normal breathing pattern can increase the mechanical load of the respiratory system, especially in men and during the exhalation phase. © Springer-Verlag Berlin Heidelberg 2007.
