[The relation between nutrition and pulmonary ventilation in patients with chronic obstructive pulmonary disease during the relieved period].
To observe the effect of nutrition on pulmonary ventilation in aged patients with chronic obstructive pulmonary diseace (COPD) during the relieved period, the pulmonary function (MVV, PVC, FEV1, MMEF) of 261 aged patients with COPD was tested during the relieved period. The results showed that the MVV (48.75% +/- 19.9%) tested in the patients with malnutrition was significantly lower than that tested in the patients with normal nutrition (59.1% +/- 22.6%) (P < 0.01) while there was no marked difference in the ventilation in their large and small airway. It is conluded that malnutrition of the patients with COPD affects the constrictive function of respiratory muscle and thus results in a decrease in MVV.
