6 Neonatal ventilation
Calibrate the infant flow sensor between patients, after
installing a new flow sensor, or whenever the
Flow Sensor
Cal.needed
alarm activates.
Unlike for the pediatric/adult flow sensor calibration, you DO
NOT turn the infant flow sensor during calibration. During flow
sensor calibration, the device can recognize a mismatch bet-
ween the set patient type and the flow sensor in use.
In response it actuates a
Flow Sensor Mismatch
alarm.
6.4 Test and calibration
Just as you would do for any patient, you must conduct a pre-
operational check described in Section 4.2 before placing your
infant/neonatal patient on the ventilator.
The instructions include:
• A test for leak-tightness of the breathing circuit
• Calibration of the infant flow sensor
• A pre-operational check of the device to support an infant/
neonate. The pre-operational check does require an infant/
neonatal lung model.
6.5 Ventilation modes and mode additions
WARNING
Auto triggering is harmful and can easily occur at
sensitive trigger settings (flow or pressure) from
gas leaks around the ET tubes.
NOTE:
As neonatal ET tubes normally do not have a cuff, leak-
age can be significant (that is, VLeak can be much
greater than the measured expiratory tidal volume (VTE).
Check the VLeak parameter in the Monitoring window
from time to time; such a leak is not be predictable.
To begin ventilating neonatal patients, you must first select and
activate the neonatal patient profile.
