proceed as follows.
1. Connect the connector of the connecting cable to the therapy device and latch it with the bayonet fitting.
2. Connect the cables at the other end of the connecting cable to the in-hospital nurse call system. To do so, see
the brief instructions for use for the connecting cable.
2.7.2 VENTIremotealarm
For operation with the VENTIremotealarm remote alarm box, see the associated instructions for use.
2.8 Use with nebulizers
You can use the therapy device with pneumatic nebulizer sets made by other manufacturers. A prerequisite for this
is that the nebulizer is designed by the manufacturer for use in combination with a ventilator.
General information
• When using the device in conjunction with nebulizers, be sure to adhere to the cleaning intervals for the patient
circuit and even reduce these if necessary, as residues of medication can impair valve function.
• When used with a double patient circuit, the exhalation block for measuring flow on exhalation must be cleaned
after use of the nebulizer.
• It is essential to follow the instructions for use for the therapy device and for the nebulizer used.
• The manufacturer is unable to make any statements in relation to medication dosages and the efficacy of aerosol
therapy. Contact the manufacturer of the nebulizer used for information on this.

18 Operation
EN
Pneumatic nebulizers
When pneumatic nebulizers are used, deviations in respiratory volume and oxygen concentration may occur
between the values displayed and those actually administered. The ventilator may exhibit modified trigger
characteristics depending on the amount of deviation in respiratory volume.
In this case, it will be necessary to reset ventilation parameters and alarm settings before and, if appropriate, during
administration of the medication. The patient needs close monitoring during use. As a result, pneumatic nebulizers
may only be used in combination with the therapy device in a hospital environment.
Our experience shows that pneumatic nebulizer sets may only be used with the therapy device at a maximum
supply flow of up to 8 l/min and with the corresponding flow controller.
Nebulizer ref. 8-4026-100 from B+P and the Oxinova Nebulizer II from Carburos Medica have been tested.
Micropump nebulizers
We recommend the Aeroneb Solo/Pro nebulizers from Aerogen. These can also be used in a domestic environment.
