Brief Summary

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

The goal of these studies is to assess the use of phonocardiograhy to monitor blood volume. We will evaluate phonocardiographic parameters in normal subjects in increasing levels of lower body negative pressure (LBNP) and lower body positive pressure (LBPP).

Lower Body Negative/Positive Pressure

Group Type OTHER

Fluid shift

Intervention Type DEVICE

We are using lower body negative and positive pressure to create a fluid shift in the body. This study is investigating if there are changes in phonocardiographic parameters related to changes in blood volume caused by this fluid shift
