[Continuous noninvasive recording of circulatory parameters while performing the Valsalva test under elevated ambient pressure].
The results are presented which confirm applicability of the Valsalva test as a functional exercise for the cardiovascular system while studying changes of the circulation regulation under high ambient pressure. Methods of transthoracic tetrapolar impedance plethysmography, electro- and intervalocardiography and mean arterial pressure measurement by means of the oscillometric servosystem are shown as adequate and highly informative under these conditions.
