A support for a chest compression system includes a back plate, a front part having a seat for a compression member of a chest compression system, and a side part connecting the back plate to the front part. A part of the drawn liquid is discharged to the outside of the distillation apparatus while the rest is flowed to the reboiler. Seismic accelerations applied to the base of the seismic and gravity sensor, or changes in the gravitational field, generate loads that are transmitted to force-sensitive resonators so that changes in resonant frequency are related to the applied load.
