Respiratory pressures in normal Indian subjects.
Regression equations for the prediction of maximum inspiratory pressures (MIP) in North Indian adults are reported, based on observations in 120 females and 153 males. Age and sex were the only significant predictor variables. MIP was significantly related to vital capacity, FEV1 and peak flow rate. The MIP observed in the present study are similar to those reported earlier in Caucasians and Chinese. The lower lung volumes and flow rates in Indians are not explained by differences in MIP.
