Key result
In vitro evaluation of a pneumatic LVAD demonstrated non-physiologically high and low pressures, while simulated testing of a spinal implant strain gauge showed a <1.5% fall in quasi-dynamic strain.

Withington et al. (1991) studied this question. Thermo Cardiosystems mark 14 pneumatic LVAD and electrical resistance strain gauge was evaluated on Pressure-volume loops and strain gauge performance. In vitro evaluation of a pneumatic LVAD demonstrated non-physiologically high and low pressures, while simulated testing of a spinal implant strain gauge showed a <1.5% fall in quasi-dynamic strain.
