Apnea Ventilation

For switching over automatically to volume-
guaranteed mandatory ventilation in case of apnea.

Flow
For Babylog VN500 to be able to detect an apnea,
neonatal flow measurement must function and neo-
natal flow monitoring must be activated.
Babylog VN500 detects an apnea when no expira-
tory flow is measured or insufficient inspiratory gas
is delivered during the set apnea alarm time Tapn.
If apnea ventilation is activated, Babylog VN500
starts volume-guaranteed ventilation with the venti-
lation parameters RRapn and VTapn. The inspira-
tory time for apnea ventilation is determined from
the set apnea respiratory rate RRapn and a fixed
I:E ratio of 1:2.
The patient can breathe spontaneously and the
mandatory breaths are synchronized with the pa-
tient's spontaneous breathing. The apnea ventila-
tion respiratory rate RRapn remains constant.
Babylog VN500 provides synchronized intermittent
mandatory ventilation.

Apnea ventilation is terminated by touching the
Apn. Vent. reset button. Babylog VN500 continues
ventilating in the previously set ventilation mode.
Changing the ventilation mode or additional set-
tings, e.g., PS, also terminates apnea ventilation.
If an apnea situation generating an alarm occurs
again during apnea ventilation, this indicates that
the apnea ventilation respiratory rate RRapn has
been set too low in relation to apnea alarm time
Tapn.
Automatic return from apnea ventilation
If the Auto return from Apnea Vent. function is
configured, Babylog VN500 automatically switches
to the previous ventilation mode when sufficient
spontaneous breathing is resumed. The following
conditions must be met:
