摘要： A gas-mixing device for respirators can be used both in stationary operation and in mobile operation. The gas-mixing device has a storage tank (5), into which compressed air and oxygen can be introduced by dispensing valves (3, 8). In addition, a blower (10), which draws in gas from the environment (11), is connected to the storage tank (5). To dispense gas from the pressurized gas sources (4, 6) by means of the dispensing valves (3, 8), a first operating pressure level is set in the storage tank (5). When changing over to the blower operation, the operating pressure level is lowered to a pressure level adapted to the maximum respiration pressure.

摘要： A device with a gas sensor for measuring a breathing gas component in a breathing gas line is improved such that a pressure correction of the gas concentration measurement can be performed without appreciably affecting the respiration pressure. Provisions are made for branching off a first measuring gas line (23) with a first electrochemical measuring cell (28) from the breathing gas line (7). A first throttling point (26) is arranged in the course of the first measuring gas line (23) between the first electrochemical measuring cell (28) and the breathing gas line (7). A first pressure sensor (29), for the pressure correction, is located downstream of the first electrochemical measuring cell (28).
