1. A method of regulating the level of exufflation pressure and / or the rate of change of pressure of a compressed stream of respiratory gas delivered to a subject, the subject having airways, the method comprising the steps of: creating a compressed stream of respiratory gas for delivery to the subject’s airways insufflation pressure before the transition time; identify the transition time based on one or more insufflation parameters; in response to the identification of the transition time, reduce the pressure of the compressed respiratory gas flow from insufflation pressure level to exufflation pressure level; determine the value of the flow rate during exhalation by the subject, where the flow rate indicates the flow from the lungs of the subject during exhuffation; obtain the target level of flow rate; compare the determined value of the flow rate with the target level of flow rate, which corresponds to the target speed gas flow from the lungs of a subject; one or more of exsufflation pressure, one or more insufflation parameters, or one or more parameters are controlled Navigate insufflation / ekssufflyatsii based on comparing the determined flow parameter value with a target level flow indicator; realizing the adjusted exufflation pressure, the adjusted one or more insufflation parameters and / or the adjusted one or more insufflation / exufflation transition parameters during subsequent breathing. 2. The method according to claim 1, in which in response to a certain value of the flow rate, which is less than the target level of the flow rate, exhuffation pressure, one or more parameters1. Способ регулирования уровня давления экссуффляции и/или скорости изменения давления сжатого потока дыхательного газа, доставляемого субъекту, причем субъект, имеет дыхательные пути, при этом способ содержит этапы, на которых:создают сжатый поток дыхательного газа для доставки в дыхательные пути субъекта на уровне давления инсуффляции перед временем перехода;идентифицируют
