Difference of Respiratory Function Between Spleen-qi Deficiency Pattern and Lung-qi Deficiency Pattern in Chronic Obstructive Pulmonary Disease / 广州中医药大学学报

ABSTRACT

To explore the difference of respiratory muscle strength and respiratory drive between lung qi deficiency pattern and spleen qi deficiency pattern in chronic obstructive pulmonary disease (COPD).Forty two cases of COPD were differentiated as lung qi deficiency pattern (n=23, Group A) and spleen qi deficiency pattern(n=19, Group B) and twenty healthy volunteers served as control (Group C). Pulmonary ventilatory function such as forced vital capacity(FVC), forced expiratory volume in one second (FEV 1), FVC/ FEV 1 and maximum voluntary ventilation (MVV) were examined; and the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and oral blocking pressure were also detected.As compared with Group C, pulmonary ventilation was decreased in both Group A and Group B and more obviously in Group B (P0 05); MIP and MEP in Group B differed from those in Group C (P
