Abstract: An apparatus and method for preventing hypovolemic shock to a human body. While the human body is in a sitting position, venturi jets fixed to one another emit pressurized water to contact the frontal and rear areas of the lower extremities and backside of the upper torso. The venturi jets are vertically displaced along the contours of the lower extremities and backside as the water from the venturi jets continually contact the lower extremities and backside at generally perpendicular angles thereto.
