An arrangement in apparatus with which a gas orgaseous mixture is spontaneously inhaled or forcefully induced into the respiratory system of a patient. The gas or gaseous mixture is taken from a pressurized gas-source and administered to the patient through a face mask (12) or tracheal tube (13). A valve means is provided for controlling the flow of gas from the gas source to the patient. According to the invention, the valve means (11) is placed between the face mask (12), or tracheal tube (13), and a nipple (10) connected to the gas-supply line. The valve means is arranged so that the supply of gas from said gas source can be controlled manually in a continuous fashion, between a first state in which the flow of gas to the patient is fully blocked and a second state in which the gas flow is at a maximum. |
