title: A preliminary investigation into maximal expiratory pressures in some village children.
abstract: A clinical mercury sphygmomanometer was used to measure Maximal Expiratory Pressure (MEP) in 29 boys (mean age 8 +/- 1.4 yr) and 21 girls (mean age 7.6 +/- 1.5 yr) of a village in interior Maharashtra. The values of 70.6 +/- 13.4 mmHg SD for the boys and 61.9 +/- 18.9 mmHg for the girls were quite comparable to the respiratory pressures reported elsewhere in literature, even though the subjects were apparently poorly nourished. There was no statistical difference between the MEPs of boys and girls. The MEP was positively and significantly (P<0.01) correlated to height (r=0.51) and weight (r=0.05) in the boys. The MEP denoting respiratory muscle strength also correlated positively with handgrip power used to represent non-respiratory muscle strength (r=0.34) (P>0.05). The simple, reproducible method of measuring MEP as described may be useful for measuring this important physiological parameter at the bedside in children whose respiratory muscle function needs to be evaluated.
