TIRADO, Karina  y  VILLENA, Mercedes. DETERMINATION OF DISTANCE AND CHANGE IN RESPIRATORY AND CARDIOVASCULAR PARAMETERS BEFORE AND AFTER THE 6 MINUTES WALK TEST IN NATIVE AND PERMANENT RESIDENTS OF CLINICALLY HEALTHY ALTITUDE. Rev. Méd. La Paz [online]. 2014, vol.20, n.1, pp.5-11. ISSN 1726-8958.

Objective: Determine the distance and the variation of respiratory and cardiovascular parameters before and after the walk test 6 minutes (6MWD) in native and permanent residents of the clinically healthy altitude. Methodology: The type of study design responds to a pre and post test research. We worked with 64 people, 33 women and 31 men, clinically healthy between 20 and 30 years, previous informed consent proceeded according to internationally established protocol. The test consisted of measuring the distance each participant could walk in 6 minutes. As established and applying non-invasive methods, the presence of dyspnea was assessed, changes in heart rate, respiratory rate and oxygen saturation (SO2) at the beginning, end and at 5 minutes of the test. All data were recorded immediately in the relevant forms and subsequently transcribed in a computerized data basis for statistical analysis. Results: Significant differences in heart rate and oxygen saturation were found between groups. Heart rate increased in both groups after the hike and kept at 5 minutes of recovery. Post hike a SaO2 decreased in females, while in males, increased. Women reported weak dyspnea and men showed no dyspnea. We compared the values obtained in our participants with the existing reference values (Enright - norteamerican population and Osses - chilean population) and significantly lower results being obtained. Conclusion: The 6MWT is entirely feasible but the formulas used at sea level, can't be applied in our study and a statistically acceptable sample population is required to obtain formulas to reference values for altitude.
