Operation
8.4 Special forms of therapy
The device has the following additional operation modes:
– External fresh-gas outlet
– Pause
1)
– Monitoring
2)
–CBM mode
8.4.1 External fresh-gas outlet
Prerequisites:
– The device has the "external fresh-gas outlet" hardware option.
– A non-rebreathing system is connected, see page 91.
Redirecting the fresh gas to the external outlet
The FiO
2 measurement is not possible when the external fresh-gas outlet is in use
on devices with inspiratory O
2 measurement, as the fresh gas is not routed through
the internal breathing system.
WARNING
Risk of faulty gas delivery
With non-rebreathing systems, O
2, CO2, and any anesthetic gases must be
monitored.
► Connect the sample line to the non-rebreathing system and the integrated
patient-gas measurement module or the anesthetic gas monitor.
CAUTION
Risk of gas contamination
When the device’s integrated patient-gas measurement module is used, the
extracted sample gas is also returned to the internal breathing system during
operation with an external fresh-gas outlet.
► Using a breathing hose, establish a closed connection between the inspiratory
port and the expiratory port. Flush the breathing system each time patients or
anesthetic gas are changed!
1. Start the Ext. FGO operation mode.
2. Adjust the fresh-gas delivery. Check the vaporizer setting.
8.4.2 CBM mode
The CBM mode allows patient monitoring without unnecessary alarms during
extracorporeal oxygenation of the patient by a heart-lung machine.
Properties of CBM mode:
– All gas concentrations are measured independently of the respiratory phases.
–The CO
2 apnea alarms and pressure apnea alarms are inactive.
– Further configurable alarms are inactive, see pages 196 and 209.
The CBM mode can be used in all active ventilation modes.
1) Pause must be activated in the system setup.
2) Only for devices with integrated PGM. Pause must be deactivated in the system setup.
