Methods and apparatus provide for operating at least one respirator in a communication network, where the communication network (II) has at least one processing unit, a cloud, and the at least one processing unit has a computing unit, and the at least one respirator is connected to the communication network via a communication module. The respirator data from the at least one respirator is transmitted to the communication module and then the transmitted respirator data is sent from the communication module to the at least one processing unit. The sent respirator data is analyzed in the at least one processing unit, the analyzed respirator data is revised in the computing unit and then transferred from the at least one processing unit to a communication module and/or from the at least one processing unit to at least one external receiving unit.
