Abstract
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 depending on at least one parameter of the respiration of the patient.
Claims21
A method for administering at least one medical gas to a patient mechanically ventilated by means of a ventilator,
- in which a first end of a first line supplying at least respiratory gas from the ventilato, a first end of a second line discharging at least exhaled gas from the patient and a first end of a patient feed line are connected to one another via at least one connecting piece,
- by means of the ventilator at least in one portion of the first line a respiratory gas flow is produced, and
- in which the medical gas is introduced into the first line supplying the respiratory gas,
- wherein a gas source for providing the medical gas to be administered and the first line are connected via at least two regulating means arranged in parallel, wherein a connection is established between the gas source and the first line via each regulating means in the opened state,
- in that multiple gas pulses of the medical gas are fed successively into the first line by means of the regulating means, and in that the gas pulses depending on at least one parameter of the respiration of the patient are fed.
A device for administering at least one medical gas to a patient mechanically ventilated by means of ventilator,
- having a first line supplying at least respiratory gas from the ventilator,
- having a second line discharging at least exhaled gas from the patient,
- having a patient feed line, wherein a first end of the first line, a first end of the second line and a first end of the patient feed line are connected to one another via at least one connecting piece,
- having a ventilator which produces at least in one portion of the first line a constant respiratory gas flow, and
- having supply means for supplying the medical gas to the first line supplying the respiratory gas,
- wherein there are at least two regulating means arranged in parallel which connect a gas source for providing the medical gas to be administered and the first line, wherein each regulating means in the opened state establishes a connection between the gas source and the first lin, and
- having a control unit which controls the regulating means such that at least one regulating means successively feeds multiple gas pulses of the medical gas into the first line, and
- in that the control unit depending on at least one parameter of the respiration of the patient controls the regulating means .
