reduce the power-setting of the suction system accordingly if suctioning in a closed system
/ in-line suctioning or any other PEEP-saving suctioning procedures. If in doubt, disconnect
the anesthesia device for endotracheal suctioning (consider the loss of PEEP). Alternatively,
by disconnecting the manual breathing bag you can ensure that the bag won’t collapse due to
the suctioning. By this measure, the potential of negative pressures in the system is reduced.
Pay special attention to the fact that after the suctioning the manual breathing bag has to be
reconnected by the user.
4.9 Nebulization of drugs and aerosol therapy
- Nebulization of drugs and aerosol therapy are not approved with anesthesia devices. If
aerosol or other drugs are given to the airways, malfunctions can occur. Without a mechanical
filter between the connection port of the nebulizer and the anesthesia device, malfunctions are
very likely to occur (e.g. incorrect measurement of the gas analyzer, erroneous measurement
of expiratory flows, tidal and minute volumes). If no mechanical filter is used on the Y-piece,
disconnect the sampling gas line during nebulization and aerosol therapy.
4.10 In case of failure
- If a main component of the anesthesia device , such as the mixer, ventilator or screen shows
a failure, immediately switch to an alternative means of ventilation .
5 Consumption of fresh gas and soda lime
- Dräger anesthesia devices work with an electronically driven ventilator (piston ventilator in
Apollo and Fabius- family devices; blower ventilator in Perseus). Thus these devices do not
consume any driving gas, and the consumption of gases supplied by the central gas supply or
from cylinders equals the fresh gas flow settings. For Example, if your fresh gas setting is FG-
Flow 9 L/min and FG-O
2
-concentration 50%, this will lead to a consumption of approx. 5.7 L/min
AIR and 3.3 L/min O
2
. Please note that when using a
ctive scavenging (AGS)
the consumption of
centrally supplied gases will be higher.
