dc.description.abstractIntroduction: Globalized human activities have forced human beings to migrate to different places, occasionally of higher altitude to live. The body must make adjustments to its metabolic processes through the acclimatization of its organs and systems to hypoxia (Bell, 2000). This research deepens the knowledge on hematological and ventilatory variables in university students who come from the lowlands in order to identify trends that allow expanding knowledge about the population's response to acute changes in altitude. Objective: To establish the time course in ventilatory and hematological changes in university students from the lowlands during a short period of time. Methodology: The present study is descriptive longitudinal and observational type. The ventilatory variables such as respiratory rate (Rf), tidal volume (Vt), respiratory quotient (QR), partial pressure of oxygen (PetO2) and partial pressure of carbon dioxide (PetCO2) at the end of the exhalation at rest will be recorded (gas analyzer Cosmed) and hematological variables such as hemoglobin concentration ([Hb], OSM3 hemoximeter), hematocrit (Hct, microcentrifugation), total hemoglobin mass (Hbt, CO re-inhalation method) and blood volumes. Results and Discussion: Statistical significance was found in variables such as hematocrit (p=0.03), plasma volume (p=0.02), mean corpuscular hemoglobin concentration (p = 0.05), carbon dioxide pressure (p=0.02), quotient respiratory (p=0.02) in some elements of the determination. Conclusion The findings of this study show slight ventilatory and hematological alterations with acute changes at moderate height in the university student population. Total hemoglobin mass (Hbt) increased non-significantly, which differs from that reported in previous studies, possibly due to less altitude change or limitations of the sample used. Key words: total hemoglobin mass, ventilatory frequency, respiratory quotient, moderate height; acclimatization to hypoxia.spa
dc.description.abstractIntroducción: Las actividades humanas globalizadas han obligado al ser humano a migrar por diferentes razones a sitios, ocasionalmente de mayor altitud para vivir. El cuerpo debe realizar ajustes de sus procesos metabólicos mediante la aclimatación de sus órganos y sistemas a la hipoxia (Bell, 2000). En esta investigación se profundizan los conocimientos sobre las variables hematológicas y ventilatorias en universitarios que provienen de tierras bajas a fin de poder identificar tendencias que permitan ampliar el conocimiento sobre la respuesta de la población a cambios agudos en la altura. Objetivo: Establecer el transcurso de tiempo en los cambios ventilatorios y hematológicos en universitarios provenientes de tierras bajas durante un periodo corto de tiempo. Metodología: El presente estudio es de tipo descriptivo longitudinal y observacional. Se registrarán las variables ventilatorias como son frecuencia respiratoria (Rf), volumen tidal (Vt), cociente respiratorio (CR), presión parcial de oxígeno (PetO2) y presión parcial de dióxido de carbono (PetCO2) al final de la exhalación en reposo (analizador de gases Cosmed) y las variables hematológicas como son concentración de hemoglobina ([Hb], hemoxímetro OSM3), hematocrito (Hct, micro centrifugación), masa total de hemoglobina (Hbt, método de re inhalación de CO) y volúmenes sanguíneos. Resultados y Discusión: : Se encontrón significancia estadística en variables como hematocrito (p=0.03), volumen plasmático (p=0.02), concentración de hemoglobina corpuscular media (p=0.05), presión de dióxido de carbono (p=0.02), cociente respiratorio (p=0.02) en algunos momentos de la determinación. Conclusión Los hallazgos de esta estudio muestran alteraciones ventilatorias y hematológicas leves con cambios agudos a la altura moderada en población estudiantil universitaria. La masa total de hemoglobina (Hbt) aumentó en forma no significativa, lo cual difiere de lo reportado en estudios previos, debido posiblemente al menor cambio altitudinal o a limitaciones de la muestra utilizada. Palabras clave: masa total de hemoglobina, frecuencia ventilatoria, cociente respiratorio altura moderada; aclimatación a la hipoxia.spa
