A tonometric cell (3) is mounted to a g-protective suit (1) working according to the hydrostatic principle, for example at the lowest point of a fluid- transporting vein (2) generating, through its internal pressure, the peripheral tension required by the g-protective suit (1). The changes in volume occurring in the person wearing the g-protective suit (1) while breathing generate changes in pressure which are measured by the tonometric cell (3) and are transferred to an evaluating device, for example via a cable (5). A display device and a storing device can be connected to the evaluating device.

Selon l'invention, un capteur de pression (3) est placé sur une combinaison de protection contre les effets de l'accélération (1), fonctionnant sur le principe hydrostatique, par exemple au point le plus bas d'un tube (2) transportant un liquide, ce tube générant par sa pression interne la tension de circulation nécessaire à la combinaison (1). Les variations de volume de l'utilisateur de la combinaison (1) provoquées par la respiration de celui-ci entraînent des variations de pression qui sont mesurées par le capteur de pression (3), puis transmises à un appareil d'évaluation, par exemple par l'intermédiaire d'un câble (5). Un dispositif d'affichage et un dispositif de stockage peuvent être connectés à l'appareil d'évaluation.
