In Air Mix mode, the applied tidal volume VT is reduced at high airway pressures due to the physical characteristics of the injector used for the mixing and the O2 concentration increases due to the smaller amount of air intake. (See also page 30 in the appendix). WARNING!
Set »Pmax« When the patient is connected: 1 Check the »MV« setting and adjust according to the patient. 2 Check the airway pressure on the pressure gauge. 3 Set desired upper alarm limit »Pmax«. When the desired upper alarm limit set »Pmax« is reached, the machine limits the airway pressure increase by blowing off part of the inspiratory flow. Inspiration is continued by the machine.

Preparation
Connecting the O2 supply Take care when handling oxygen. WARNING!
O2 is highly flammable and intensively propagates any source of fire. Do not smoke or allow any naked flame in the vicinity of the O2 supply. Protect O2 cylinders against falling, and do not expose them to intense heat. WARNING!
Do not oil or grease O2 fittings, such as cylinder valves and pressure-reducing valves, and do not handle these parts with greasy hands. Fire risk. WARNING!
Only open/close cylinder valves by hand, turning evenly. Never use a tool to open/close the valves.
For supply by O2 cylinder WARNING!
Use only compressed gas cylinders that conform to national safety standards and have been duly approved. Use full cylinders with 200 bar cylinder pressure. z Screw a pressure-reducing valve onto the O2 cylinder (for supply pressure 2.7 to 6.0 bar). WARNING!
Use only pressure-reducing valves with an outlet exhaust valve that limits the outlet pressure to approx. 5 bar in the event of failure. z Connect the Oxylog 1000 to the pressure-reducing valve with the compressed gas hose. z Open the cylinder valve by turning slowly as far as it will go.
