    A new experimental system delivers synchronized lower body pressure pulsations using a microcomputer and electro-pneumatic controls. Initial tests in a Dynamic Flight Simulator show promising results with human volunteers.

    Area of Science:

    • Biomedical Engineering
    • Aerospace Medicine

    Background:

    • External pressure pulsations can aid physiological regulation.
    • Existing systems may lack precise control over pulsation parameters.

    Purpose of the Study:

    • To describe a novel experimental system for synchronized lower body pressure pulsations.
    • To detail the system's hardware and software capabilities.
    • To present initial human testing results.

    Main Methods:

    • Design of a microcomputer-controlled system with a real-time interface.
    • Integration of an electro-pneumatic subsystem for rapid pressure pulse delivery.
    • Utilizing a modified anti-G suit for pressure application.
    • Testing with human volunteers in a Dynamic Flight Simulator.
