Operation of the Pendulum System (Bain Circuit)
The Bain Circuit supplements the basic unit perfectly for anesthaesia of smaller patients. It contains no breathing
valves. The anesthetic gas is transported directly from the evaporator via the fresh gas pipe to the patient. This
ensures quicker wash-in and wash-out even with a smaller minute volume.
The exhalation takes place into the breathing bag, and in the case of overpressure air is transferred via the open
valve in the exhaust pipe.
The pressure relief valve should always be fully opened during spontaneous breathing (against clockwise direction).
A re-breathing of exhaled carbon dioxide is prevented by the influx of fresh gas into the breathing bag (open
system).
Recommended quantity of fresh gas for wash-in: 800 ml - 1000 ml/min
Concentration of Isoflurane: 2.5% - 3.5%
Maintenance values as required, but at least 500 ml/min fresh gas (depending on evaporator).
Please pay attention to the correct assembly of the anesthaesia system, as shown in the picture above.
