Spn-Cpap/Vs - Dräger Babylog VN500 Instructions For Use Manual

Description

SPN-CPAP/VS

Spontaneous-Continuous Positive Airway Pres-
sure/Volume Support
Spontaneous breathing with continuous positive
pressure level with or without volume support
For volume support VS, every inspiratory effort by
the patient on PEEP level that meets the trigger cri-
teria triggers a volume-supported breath. By setting
the trigger level, the patient's inspiratory efforts are
synchronized. The time, number, and duration of
volume-supported breaths is determined by the pa-
tient's spontaneous breathing. The pressure rise is
determined by the Slope or Insp. flow setting. The
start setting can be configured on the page System
setup > Ventilation > Start settings > Pressures,
O , I:E.

The volume support is terminated as soon as the
inspiratory flow falls below 15 % of the maximum
inspiratory flow.
The volume support is also terminated as soon as
the duration of the support has reached the maxi-
mum inspiratory time. For intubated patients, the
maximum inspiratory time in the Ped. pat. patient
category is limited to 1.5 seconds. For the Neo. pa-
tient category, the maximum inspiratory time can be
set with Timax to a maximum of 1.5 seconds.
The set tidal volume of the supported breaths is
reached through the automatically selected pres-
sure level of the volume support. With volume sup-

port, the support pressure is automatically adjusted
to changes in lung conditions (resistance and com-
pliance) and to the spontaneous breathing demand
of the patient.
If Paw high is linked to the therapy control
Pmax, set the maximum pressure that can be
applied with the Pmax setting!
If Paw high is not linked to the Pmax therapy
control, always set the Paw high alarm limit so
that Babylog VN500 generates an alarm in the
event of an increase in airway pressure due to
reduced compliance. The maximum pressure
that can be applied is limited to 5 mbar
(5 cmH O) below the upper alarm limit.
