Résumé
Purpose of Study: To measure CV responses in SLF, and SQ with & without VM, Study design: Cross sectional Observational study, Materials: assessment form, 36 SF Health Questionnaire, Modified Sphygmomanometer, BP apparatus, Nike-HRM-TRIAX, Methodology: 335 (M=146) subjects participated to perform SLF and SQ position with & without VM and SBP, DBP and HR were recorded. Data Analysis: SPSS -10.1, LOS was set at 0.05 or CI 95 %. Result: Study has shown significant increases in SBP in SQ and increase HR in SLF position with and without VM. Discussion: the impact of Heart Rate Variability and baroreflex sensitivity in CV system plays vital role in maintaining hemodynamic status while performing valsalva like activities. Conclusion: SQ has significant impact on SBP and DBP as compared to SLF position with and without VM as well as SLF position has a significant impact on HR as compared to SQ with VM, however these need to be taken into consideration while planning life style modification for high risk population.
