Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

3-D Ballistocardiography (BCG) recording was performed in microgravity during the Spacelab D2 missions on a single astronaut. The results from this experiment have been published in the literature: the influence of respiration have been demonstrated and the signal processing methodology for the reconstruction of the displacement in one cardiac cycle have been developed. A 3D-BCG sensor has been developed and a collaboration to perform a sustained microgravity experiment onboard the Russian segment of ISS has been initiated. To be integrated in the PNEUMOCARD device, this new sensor needs to be tested in microgravity before implemented on ISS.

The aim of the present parabolic flight study is to serve as a feasibility demonstrator and test bed in order to evaluate the feasibility of 3D-BCG in sustained microgravity and to test whether the sensitivity of the developed 3D-BCG sensor is appropriate
