Abstract

Improvements in a respirator with automatic control of respiratory gas flow and pressure, characterized by a flow and pressure measuring device (9) arranged directly adjacent to the patient connection (10) to measure gas flow and pressure To convert these parameters into electrical signals, a valve system (2, 3) arranged between the source of the respiratory gas and the flow and pressure measuring device to control the flow and pressure of the respiratory gas during inhalation and exhalation and an electrical control device (13) that forms a control circuit together with the measuring device and the valve system to compare the electrical signals with set values and to generate a correction signal influencing the valve system.
