Valores Espirométricos en Estudiantes de Medicina de la Universidad Mayor de San Simón (Junio ; Diciembre 2009)

Abstract

Background: Spirometric values are an invaluable test of health screening of the respiratory and identifying individuals\nat risk for lung disease, it is therefore important to establish reference values of each community.\nObjectives: To determine the values of peak expiratory flow (PEF) and Forced Expiratory Volume in one second\n(FEV-1) students of the Faculty of Medicine of the Universidad Mayor de San Simón, period June-December 2009;\nalso determine average values FEM in students who smoke and nonsmokers, and those who do physical exercise\nand students not healthy or lung disease and / or heart disease.\nMaterials and methods: In this prospective, longitudinal study. Sample 221 students (18-25 years). We used the\npreset measurement technique using a spirometer internationally Microlife ® manual. Data were collected on a\nlog sheet and statistical analysis (t-Student and correlation) was performed in SPSS.\nResults: The mean values of PEF in L / min were 517,28 ± 145,19 in healthy subjects, 421,42 ± 156,04 in people\nwith lung disease and / or heart rate (p = 0,00) in people smokers and 523,74 ± 151,03 426,31 ± 154,81 in nonsmokers\n(p = 0,00) and between people and athletes 466,72 ± 160 424,86 ± 155,61 in non-athletes (p = 0,071)\nThe average values of FEV-1 in L / sec were: 3,39 male (18-20 years) and 3,76 (21-25 years), women 2,79 (18-20\nyears) and 2,72 (21-25 years).\nConclusion: The values of PEF and FEV-1 are lower than international values, and are in direct relation to height.\nHealthy people, smokers have a higher PEF value.
