- Before connecting a patient, the user must be able to check the proper device status, ensure
that all accessories (e.g. ventilation hoses, bacteria filter, gas sampling line, manual breathing
bag, water traps) are properly connected and that the device is able to generate gas flow and
pressure at the patient connector. With the exception of Australia and New Zealand, the
connectors for the manual breathing bag and ventilation hoses have the same diameter.
Therefore, the risk of incorrectly connected patient hoses is given. A false connection (e.g. bag
hose connected to inspiratory port) would make the ventilation of the patient impossible. As a
result, particularly when connecting a patient to an anesthesia device, the user requires
device knowledge and clinical experience with anesthesia devices. Directly before
connecting the patient, the user has to check if the device is able to deliver pressure to the
patient connector and that by unblocking the patient connector the pressure can be released
and gas can flow out (see e.g. website of European Patient Safety Foundation:
https://www.eupsf.org/safety-alert-wrong-tube-connections)
2.2 Location requirements
- Anesthesia devices should be used only in rooms with adequate ventilation.
- The user interface of Dräger anesthesia devices cannot be protected against non-authorized
users. Therefore, the operating organization must ensure that non-authorized users
cannot approach the device to avoid settings being changed, or therapy being stopped (no
alarm is generated when the device is switched to standby).
2.3 Manual resuscitator
- The instructions for use state a manual resuscitator must always be available at the device
which enables back-up ventilation of the patient in case of problems or malfunctions with the
device. Particularly for users with limited knowledge of anesthesia devices, it is particularly
important that in case of irregularities or unexpected system behavior impairing patient
therapy, the patient has to be disconnected from the anesthesia device and ventilated with an
operator powered resuscitator. Due to the situation of the patient, it is recommended that you
have a manual resuscitator available that allows the application of a PEEP.
