An inflatable vest capable of monitoring and controlling the amplitude and phase of respiratory motion, the inflatable vest comprising front pieces (1), a back piece (2), at least one inflatable layer (8), in the front pieces (1) and back piece (2), divided into an inner layer, an outer layer, and a middle, and at least one of the front pieces (1) and back piece (2) are made of a polymeric material impermeable to air. The inflatable vest may be connected to a pressure measurement device (11), i.e. a flow sensor (14) or pressure sensor (13), and by means of the pressure measurement device (11), the pressure of the gas in the inflatable layer (8) of the inflatable vest is monitored in real time and changed into an electrical signal. In the inflatable vest, the front piece inner layer (1) and outer layer can be directly stitched or adhesively fixed on a vacuum pad (14), the vacuum pad (14) serving as the back piece (2), thus forming a combination inflatable vest or, after a body membrane is fixed, the inflatable vest is again placed below the body membrane and used in combination. By means of monitoring and controlling the pressure inside the inflatable vest inflatable layer (8), the amplitude and phase of respiratory motion can be monitored and controlled in real time.Linvention concerne un gilet gonflable pouvant surveiller et contrôler lamplitude et la phase dun mouvement respiratoire, le gilet gonflable comprenant des parties avant (1), une partie arrière (2), au moins une couche gonflable (8), dans les parties avant (1) et la partie arrière (2), divisée en une couche interne, une couche externe et une couche centrale, et au moins lune des parties avant (1) et de la partie arrière (2) est constituée dun matériau polymère imperméable à lair. Le gilet gonflable peut être relié à un dispositif de mesure de pression (11), cest-à-dire un capteur découlement (14) ou un capteur de pression (13), et, au moyen du dispositif de mesure de pression (11), la pression du gaz dan
