We have proposed that unsupported arm exercise alters ventilatory muscle recruitment and precipitates dyspnea in patients with severe chronic airflow obstruction (CAO). To test this hypothesis, we studied 11 patients with CAO during symptom-limited, unsupported arm exercise (UAE) and compared it with supported arm cycling (SAE). During each exercise period, we recorded endoesophageal (PpI), gastric (Pg), and transdiaphragmatic (Pdi) pressures along with heart rate, respiratory rate, and… CONTINUE READING
