METHOD AND DEVICE FOR SUPPLYING AT LEAST ONE MEDICAL GAS TO A PATIENT RECEIVING ARTIFICIAL RESPIRATION WITH THE AID OF AN ANESTHESIA MACHINE

摘要

A device and method for administering at least one medical gas (NO) to a patient mechanically ventilated by means of a ventilator. The ventilator produces a constant respiratory gas flow (O2/N2) in a feed line. Gas pulses of the medical gas (NO) are supplied to said respiratory gas flow. The gas pulses are produced by means of at least two regulating means arranged in parallel and are fed to the line. Here, a control unit controls the regulating means such that the gas pulses introduced into the feed line show a pulse repetition with constant pulse frequency.
