The Valsalva maneuver is performed by forcibly exhaling against a closed airway. Maneuver variations can be used either in medicine, as a test of cardiac function and autonomic nervous control of the heart. A modified version is done by expiring against a closed glottis. This will bring forth the cardiovascular responses but will not force air into the eustachian tubes.
