A system and a method are provided for monitoring an exhaust gas purification system that is functionally connected to an emission source. An emission sensor acquires an emission signal that indicates emissions of the emission source on the exiting from the exhaust gas purification system. In addition, measurement signals that are each related to the exhaust gas purification system are acquired by a plurality of further sensors. A process state of the exhaust gas purification system is determined based on the measurement signals of the further sensors. Then, the emission signal and the process state are assessed with respect to an anomaly in each case. A compliant emission state, which indicates a correct functionality of the exhaust gas purification system, is determined and output when no anomaly of the emission signal is present or when an anomaly of the emission signal is present while at the same time no anomaly of the process state is determined or the anomaly of the emission signal satisfies an exception condition.

A liquid electrolyte, for an electrochemical gas sensor for detecting NHor gas mixtures containing NH, contains at least one solvent, one conductive salt and/or one organic mediator. The conductive salt is an ionic liquid, an inorganic salt, an organic salt or a mixture thereof. The electrolyte preferably is comprised of (I) water, propylene carbonate, ethylene carbonate or a mixture thereof as solvent; (ii) LiCl, KCl, tetrabutylammonium toluenesulphonate or 1-hexyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate as conductive salt; and (iii) tert-butylhydroquinone or anthraquinone-2-sulphonate as organic mediator.

A devicewithdraws a breathing gas stream (A) from a ventilation system (B) and transports the breathing gas stream (A) to a gas analysis system (G). The devicehas a tubular configuration with an inner side () and with an outer side () and includes two tube sections (') and a drying stage () with an inner side (&#x2032;) and with an outer side (&#x2032;), and at least one liquid storage device (). The drying stage () includes a gas-tight and moisture-permeable material that transports moisture from the inner side (&#x2032;) of the drying stage () through the gas-tight and moisture-permeable material to the outer side () of the tubular device (). The drying stage () and/or the liquid storage device () is arranged at least partially between the two tube sections (&#x2032;).

A method and a system control a drug dosing device () for administering a drug to a patient (). The quantity (c) of the drug administered from the drug dosing device () is determined or calculated. The concentration of the drug in the gas exhaled by the patient () is measured as a first patient value (cM). A simulation calculation is carried out, in which a second patient value (cp) is calculated from the administered quantity of the drug (I), taking into account a parameter (k). A simulated first patient value (c') is calculated in the simulation calculation, taking into account the parameter (k). A comparison of the simulated first patient value (c&#x2032;) to the measured first patient value (cM) is carried out. The parameter (k) is adapted on the basis of the comparison. The calculated second patient value (cp) is used to generate a control signal (S).

An arrangement is provided for monitoring a metering of at least one medication administered to a patient. The concentration of the active ingredient of the medication, which is measured in the breathing gas of a patient, is balanced with a computed concentration in the breathing gas. When a change of the administered quantity of the medication takes place, the concentration range () is adapted. The concentration, which is measured in the breathing gas, must lie by computation within this range. An arrangement for administering at least one medication and a method for monitoring a metering or dosing of the medication as well as a method for treating a patient are provided.
