We investigated the relationship between minute ventilation (V˙e) and net respiratory muscle pressure (Pmus) throughout the breathing cycle [Total Pmus = mean Pmus, i (inspiratory) + mean Pmus, e(expiratory)] in six normal subjects performing consta

The purpose of this study was to determine whether the tachypneic breathing pattern of constant work rate, heavy exercise (CWE) is unique to CWE or whether it represents the usual pattern of the respiratory control system at high levels of ventilatio

It has been suggested that physical training causes a slower, deeper breathing pattern at a given level of ventilation, but there is no convincing evidence to support this. We examined breathing pattern during maximal incremental exercise on a cycle

Objective: To test the hypothesis that respiratory function contributes to limit maximal exercise performance in patients with chronic heart failure by using the technique of dead space loading during exercise. Design: Blinded subjects underwent two

In exercising humans, added external dead space (VD) increases minute ventilation (VI) and causes a slower and deeper breathing pattern (J. Appl. Physiol. 1991; 70:55-62). Recent studies suggest that airway receptors sensitive to topical anesthesia i

Inspiratory muscle weakness has been demonstrated in ambulatory, stable chronic heart failure (CHF) and may contribute to dyspnea during daily living. However, the mechanisms underlying this weakness are unknown. Malnutrition and electrolyte depletio

Dyspnea is a common, disabling symptom in chronic heart failure, yet the underlying mechanisms remain unknown. The respiratory muscle pump is composed of skeletal muscles whose strength directly influences the pump's performance. Respiratory muscle w
