Individualized System for Augmenting Ventilator Efficacy (iSAVE)
The existing practice of sharing ventilators between patients has serious safety concerns. We have overcome these problems with the iSAVE, a system of tubing, sensors, filters, and valves to provide individualized volume and pressure control to two or more individuals from a shared ventilator. The iSAVE was applied to open- and closed-circuit ventilators provided temporary respiratory support to two artificial test lungs or pigs with differing pulmonary compliance and resistance, measured pulmonary mechanics, and accommodated sudden flow changes or the addition or removal of an individual from shared ventilation. Through a partnership with an Indian manufacturing company, we are in the process of testing and rolling out to nations in need.
