  • SYSTEM FOR CONTROLLING THE EXHALATION PRESSURE OF A DIVER FOR DIVING VENTILATION EQUIPMENT
    Publication number: 20210086883
    Abstract: A system for controlling the exhalation pressure of a diver for diving equipment with a ventilation circuit, includes a unidirectional valve acting on an exhalation outlet of the ventilation circuit, and a brake configured to exert an adjustable constraint on the unidirectional valve in order to control the pressure of the gas from the exhalation outlet so as to generate a positive exhalation pressure in the ventilation circuit of the equipment and thus prevent or treat immersion pulmonary edemas.
