 en Short communication- A Rwandan spirometry and resting ventilation study
Jean Bosco Gahutu and Justin Wane

Abstract

To illustrate spirometric population variation and ventilatory adaptation to moderate altitude, we report the spirometric and resting ventilation values observed in a student population in Butare, Rwanda (altitude: 1 768 m; barometric pressure: 629 mm Hg). Spirometry was carried out with a Mijnhardt Volutest VT-3 water-sealed spirometer in students aged between 20 and 30 years. The results (mean ± SD) are as follows: Vital capacity: males: 4 123 ± 537 mL, females: 2 810 ± 393 mL; Vital capacity per m2 body surface area: males: 2 352 ± 245 mL/m2, females: 1 771 ± 219 mL/m2; FEV1: males: 3 576 ± 618 mL, females: 2 347 ± 474 mL; FEV1%: males: 87.8 ± 8.5 %, females: 84.5 ± 7.7 %; tidal volume: males: 540 ± 80 mL, females: 454 ± 66 mL; respiratory frequency: 17 ± 4 both in males and in females; minute volume: males: 9.3 ± 2.7 L/min., females: 7.6 ± 2.0 L/min. The results indicate that the vital capacity and the FEV1 are lower than classical values from white populations, FEV1% is higher. The tidal volume, respiratory frequency and minute volume are increased relative to sea level.
