Abstract in Portuguese
Avaliamos as mudanças no padrão respiratório, movimento toracoabdominal e ventilação em portadores de DPOC e indivíduos sadios. Estudou-se 45 indivíduos entre 45 e 75 anos conforme o VEF1. Utilizou-se sistemas de pletismografia respiratória por indutância, análise metabólica de gases em posição semi-sentada ao repouso e radiografia de tórax para a mobilidade diafragmática. Os grupos DPOC apresentaram redução do TI, TTOT, aumento do VC/TI, f, VE, das relações VEM/VC, VE/VO2, VE/VCO2 e diminuição da SpO2. Redução da mobilidade do diafragma e aumento da VEM/VC associaram-se à ineficiência da ventilação e a alterações no modelo ventilatório utilizado, sem alterações no movimento toracoabdominal.

Abstract in English
We assessed changes in breathing patterns, thoracoabdominal movement and ventilation in COPD sufferers and healthy individuals. Forty-five individuals between 45 and 75 were grouped by FEV1. Inductive plethysmographic equipment, respiratory metabolism measuring (with subject at rest in semi-recumbent position), and radiographic measurement of diaphragm mobility were used. The COPD groups presented reduction in TI and TTOT and increased VT/TI, f, VE, and VD/VT, VE/VO2, VE/VCO2 and decreased SpO2. Reduction in diaphragm mobility and increase of VEM/VC were associated with ventilatory inefficiency and alterations in the ventilatory model used. No alterations in thoracoabdominal movement
