Real time analysis of Valsalva's maneuver.

This paper describes a real-time system for the evaluation of Valsalva's Maneuver. The computer software is menu-driven and produces the parameters of linear and nonlinear models which can be used to describe the different phases of the Valsalva Maneuver. The system is routinely in use as a means of assessing baroreflex function during the Valsalva Maneuver following drug administration.
