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.
8.3.7 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
device has equipment and functions that facilitate handling of any condensed water
that is produced.
In particular cases, e.g., during minimal-flow anesthesia lasting several hours,
condensed water may accumulate in the piston ventilator.
The device detects condensed water in the piston ventilator and in the breathing
hoses during the system test. A message is displayed when condensed water is
detected.
Dräger recommends the following equipment and procedures:
– Activate the breathing system warmer to reduce condensation in the breathing
system.
– Use breathing circuits with water traps.
– Regularly remove the moisture from breathing circuits.
– Filters on the inspiration port lead to greater condensation in the breathing
system than filters on the Y-piece. Optimize the position of the filters if possible.
– Regularly check the filling level of the water traps on the patient-gas
measurement module.
– Allow the breathing system and piston ventilator to dry after low-flow anesthesia
and minimal-flow anesthesia lasting several hours, for example, by flushing with
Air from the central supply.
When performing low-flow anesthesia and minimal-flow anesthesia, follow the
recommendations of professional societies.
8.3.8 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 85.
