Mixer unit and status display

It is an electronically controlled fresh-gas delivery for O2, AIR and N2O. The mixer is provided with a Sensitive Oxygen Ratio Controller (S-ORC) to guarantee a minimum O2 concentration of 21 % (second gas = AIR) or 25 % (second gas = N2O) in the fresh-gas flow. An emergency oxygen delivery via mechanical flow meter with or without agent delivery is a safety feature in case of emergency. The mixer has an integrated oxygen therapy flow meter for flows from 0 to 10 L/min (connection for nasal cannula). Additional LCD system monitoring field for display of electrical and gas supply status as well as a scale for showing the airway pressure measurement. Please move the mouse pointer over the picture or the text next to it. The relevant area will be highlighted.
