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 anesthetized and mechanically ventilated by means of an anesthesia machine. The anesthesia machine produces a 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 and fed into a patient feed line by means of at least two regulating means arranged in parallel. Firstly, the temporal start of at least one future inhalation phase of the patient is determined. Subsequently, the regulating means are controlled by means of a control unit such that a gas pulse is fed into the patient feed line at the determined start of the future inhalation phase.
