[Effect of dead space loading on ventilation, respiratory muscle and exercise performance in chronic obstructive pulmonary disease].
To evaluate the effect of dead space (V(D)) loading on ventilation and respiratory muscle function, to test a novel measurement of oxygen consumption of respiratory muscle, and to analyze the effect of oxygen consumption of respiratory muscle on exercise performance. ⋯ Lengthening respiratory tube to 46 cm (300 ml dead space) combined with moderate constant work exercise does not worsen the airflow obstructive in COPD,or results in respiratory muscle fatigue both in the COPD patients and the healthy controls. The enhancement of V.O(2) under V(D) loading can be considered as oxygen consumption of respiratory muscle working for increased ventilation. An advantage of oxygen consumption in respiratory muscle during moderate intensity exercise in COPD implies that maintaining the balance of oxygen supplying to both respiratory and limb muscles might be the key point in performing moderate to heavy exercise.

[Physiologic response to proportional assist ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease].
To investigate the effect of different assist levels during proportional assist ventilation (PAV) on patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). ⋯ The present study confirms the feasibility of noninvasive ventilation PAV in treating patients with acute exacerbation of COPD. Based on the patient's assessment, the ventilatory support level which the patients could comfortably tolerate was (57 +/- 11)%. noninvasive ventilation PAV set at a level of comfort determined by the patient can unload inspiratory muscles; at the comfortable level of ventilatory support, Wi, Pdi and PTP decreased by 57%, 72% and 65% respectively. It also improved breathing pattern and dypnea.
