In a method for preparing gas mixtures for lung ventilators, a plurality of gases which are different from one another are supplied to a mixing chamber via switching valves, wherein the switching valves are opened and closed in a clocked manner and the pressure in the mixing chamber is monitored. The gases which are different from one another are each guided via a plurality of switching valves arranged in parallel, the switching valves being controlled in such a manner that a number of switching valves assigned to gases each different from one another, corresponding to a coarse mixing ratio is opened and closed synchronously. |
