All the neonatal modes available from the device are pressure
modes. These include: P-CMV, APVcmv, APVsimv, DuoPAP,
APRV, nCPAP-PS and SPONT.
The standard mode setting is P-CMV.
Volume-controlled modes, including (S)CMV and SIMV, are not
available.
Adaptive support ventilation (ASV) is not available.
Noninvasive ventilation (NIV and NIV-ST) are not available.
6.6 Controls
This section discusses controls that require special consider-
ation when setting up the ventilator for an infant/neonatal
patient.
See Table A-5 for standard settings for neonatal patients.
See Table A-6 for the control settings for all modes and patient
types.
6.6.1 Ti max
Ti max (maximum inspiratory time) is set for spontaneous
breaths, in P-SIMV, APVsimv, SPONT, nCPAP-PS, DuoPAP, APRV,
NIV and NIV-ST modes. For all patient types, the switchover
from inspiration to exhalation in spontaneous breaths is nor-
mally controlled by the ETS. If gas leakage is significant, how-
ever, it is possible that the setting of ETS could not be reached.
The Ti max setting provides a backup so inspiration can be ter-
minated. The HAMILTON MEDICAL ventilator switches over to
exhalation when the set Ti max is reached.
6.6.2 Flowtrigger
The default trigger type for infant/neonatal patients is flow
triggering.
