A comparative study of respiratory pattern, thoracoabdominal motion and ventilation in patients with chronic obstructive pulmonary disease modarate, severe and healthy subjectes

by Fernandes, Marcelo

Abstract (Summary)
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
