Effect of heliox on heart rate kinetics and dynamic hyperinflation during high-intensity exercise in COPD

Abstract

Respiratory mechanical abnormalities in patients with chronic obstructive pulmonary disease (COPD) may impair cardiodynamic responses and slow down heart rate (HR) kinetics compared with normal resulting in reduced convective oxygen delivery during exercise. We reasoned that heliox breathing (79% helium–21% oxygen) and the attendant reduction of operating… (More)
