Technological Advancements to the Simplified Automated Ventilator (SAVe II)
Agency / Branch:
DOD / DARPA
The proposed advancements of the SAVe ventilator will result in an easy to operate, small, lightweight, inexpensive, compressor-driven ventilator well suited not only to military applications and environments such as a battlefield (under the Tactical Combat Casualty Care doctrine), but civilian applications as well. The increased flow rate of a multiple pump design along with expanded control options of Tidal Volume, Respiratory Rate, Positive End-Expiratory Pressure, and Peak Inspiratory Pressure Limit allow the device to be safely used on a much wider patient population. The SAVe II will utilize lithium batteries to increase the operational time of the device up to 8-12 hours depending on the final configuration. The overall design of the SAVe II lends itself well to be used on a day to day basis or stockpiled for use in the event of a major pandemic. Due to lack of resources in a pandemic environment, it should be noted that the SAVe II is completely self-contained and does not require the need of a compressed gas source to operate. However, if oxygen is available, the SAVe II will accept supplemental O2 from a flow-regulated source and deliver an FIO2 range of 21-100%.
