Operation
WARNING
Risk of insufficient ventilation
The spontaneous minute volume MVspon indicates the volume which results from
spontaneous breathing and from pressure-supported spontaneous breathing. If the
patient frequently triggers pressure-supported breaths as a result of small tidal
volumes, a large part of MVspon will be achieved by mechanical ventilation and not
by spontaneous breathing of the patient. In this case, MVspon shows a high value
although the actual spontaneous minute volume is very low.
► Do not base therapy decisions solely on the value displayed for MVspon.
7.3.7 Low-flow anesthesia and minimal-flow anesthesia
This device is suitable for and optimized for carrying out low-flow anesthesia and
minimal-flow anesthesia. Functions and special characteristics are explained in the
following.
Due to the patient’s rebreathing, moisture condenses in the breathing circuit and
the breathing system, particularly during low-flow anesthesia (flow ≤1.0 L/min). The
breathing system warmer reduces this condensation.
In particular cases, e.g., during minimal-flow anesthesia lasting several hours,
condensed water may accumulate in the piston ventilator.
The device can detect condensed water in the piston ventilator and in the
breathing hoses. A message is displayed when condensed water is detected.
Dräger recommends using water traps in the breathing circuit.
7.3.8 Ventilating pediatric patients and neonates
For tidal volumes below 300 mL:
► Use suitable ventilation accessories, see chapter "Selecting and connecting
patient-specific accessories" starting on page 67.
7.4 Special forms of therapy
The device has the following additional operation modes:
– External fresh-gas outlet
– Pause
–CBM mode
7.4.1 External fresh-gas outlet
Prerequisites:
– The device has the "External fresh-gas outlet" option.
– A non-rebreathing system is connected, see page 73.
Redirecting the fresh gas to the external outlet
The FiO
2 measurement with the O2 sensor is not possible when the external fresh-
gas outlet is in use, as the fresh gas is not passed through the internal breathing
system.
