Inspiratory Capacity and Vital Capacity of Healthy Subjects 9–81 Years of Age at Moderate-High Altitude

摘要: BACKGROUND: Measurements of inspiratory capacity (IC) and vital (VC) are used to recognize dynamic hyperinflation, but appropriate reference values required achieve accurate clinical interpretations. Altitude above sea level is a potential determining factor for lung volumes, including IC VC. OBJECTIVE: To describe VC healthy people who live in Mexico City at an altitude 2,240 m level. METHODS: Healthy subjects ages 9–81 y completed slow spirometry by following 2005 American Thoracic Society/European Respiratory Society standards. Once associations were explored, linear regression models constructed compared with those from previously published equations. RESULTS: A total 441 (55.1% women) participated. The mean age was 32 (minimum age, 9 y; maximum 81 y). measurements associated sex, height, weight. An accelerated increase evident 20 followed gradual decrease both sexes. In general, higher our population than predicted CONCLUSIONS: that previous reports about European Latin-American the same present study provided robust persons lived moderate altitude.
