For legal reasons, the device instruction has to be done by my provider (Vivisol, for contact details see chapter "Important contacts"). Since my ventilation is never switched off and I only use one ventilation profile, it is not necessary to know too much about this at first.
My devices
I have two identical Astral 100's. The emergency machine must always be kept switched on with a separate hose and a second mask.
In addition to the built-in batteries, which last about six to eight hours each, I also have a travel battery with a similar runtime, which can be stored together with a machine in the special backpack for the ventilation system.
Ordinance
Note: The regulation is outdated.Trigger and the alarm limits have been adjusted.
