Original Research Article Evaluation of Cardiovascular Responses to Valsalva Maneuver in Different Body Position- An Observational Study

Background: Valsalva maneuver is regarded as a simple method to assess the baroreceptor and chemoreceptor regulated reflex activities of the autonomic nervous system. It is also advocated for the treatment of cardiovascularly stable patients. But there is a lack of integrated information which can accurately represent the response of autonomic system while performing valsalva in response to the commonly used different position. Objective: To determine the cardiovascular responses in different position and compare the response to those positions, while performing a valsalva maneuver. Methods: Thirty healthy were recruited as a sample of convenience. Different positions were assumed in the tilt table and autonomic responses were obtained before and during performance of valsalva. Results: There was a significant change in cardiovascular responses before and during the valsalva. Conclusion: Head low position caused decrease pulmonary functional parameter and supine and standing caused increase cardiac respons
