Title:
A Preliminary Investigation of a Fluid-Filled ECG-Triggered Anti-G Suit.

Abstract:
This design combines the advantages of a single reservoir fluid- filled suit with external synchronized pulses of water delivered to an abdominal bladder. Such a combination has the potential of increasing perfusion to the large muscle groups of the lower extremities, decreasing blood pooling in the lower extremities and abdomen and increasing venous return to the heart. The result is reduced fatigue and improved aviator performance during sustained high G sub z loads. During system assembly and testing, significant limitations in concept design and system safety were discovered. These limitations included excessive size, weight, and space requirements of the hydraulic system which prevented its use on the centrifuge. The inability to safely regulate the pulsatile fluid movement and other safety considerations barred its use in the laboratory. These safety considerations coupled with a lack of financial resources, over a prolonged period of time, to correct these technical problems forestalled further progress on this project. Work by other investigators in this area has superseded the expected benefit of this project. With continued budgetary reductions and no available in-house funding, this project must be terminated.
