Abstract

An arrangement for measuring bidirectional respiration flow, including a hose (1) which is connected to the breathing passages of a patient in which, via a Y-piece (2) is also connected to a tube (3) for inspiration gas and to a tube (4) for expiration gas. The tubes (3, 4) are connected to a breathing apparatus. Each tube has a venturi means arranged therein. According to the invention a pressure differential meter (8) having two inlets is connected with one inlet to each venturi means. A magnet valve (7) is arranged to periodically connect both inlets together, and there is provided an electronic means (9) for calculating the valve measured and for controlling the zero-setting, to which end the control means is connected electrically to the pressure differential meter (8) and to the magnet valve (7).
