Changing The Ventilation Mode; Synchronizing The Breaths; Ventilating Pediatric Patients And Neonates - Dräger Perseus A500 Instructions For Use Manual

Operation

Changing the ventilation mode

A
B
1 In the therapy bar, touch the tab (A) of the new
ventilation mode.
When the ventilation mode is changed, the start
settings are adopted from the parameters of the
previous ventilation mode and the patient data, or
they are sensibly derived.
In addition, the alarm settings are adjusted to
appropriate values, see page 143.
2 Adjust the therapy as needed with the therapy
controls (B) or buttons (C).
3 Activate the ventilation mode by pressing the
rotary knob. A signal tone is emitted when the
mode is changed.

Synchronizing the breaths

Turning on the synchronization activates the set
pressure support, for example, see page 258.
1 Turn the synchronization on or off with the
buttons Sync. on (A) or Sync. off (B).
2 As needed, the expanded therapy bar can be
displayed using the More buttons (C) or (D);
here, additional parameters (Trigger, ∆Psupp,
etc.) can be adapted to the patient.

WARNING
Risk of insufficient ventilation
In ventilation modes in which breaths are to
be triggered only by the patient (e.g., PSV),
adverse settings or sensor failure can lead to
insufficient ventilation.
Set the respiratory rate to a suitable value so
that a minimum ventilation of the patient is
maintained.
WARNING
Risk of insufficient ventilation
The display of the spontaneous minute
volume MVspon shows the volume that
results from the patient's own breathing and
machine support. If machine support is
triggered by small tidal volumes of the
patient, a large part of MVspon is achieved by
machine support and not by the patient's own
breathing. 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.
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 67.
For tidal volumes below 20 mL or when using
unblocked tubes:
 Use pressure-controlled ventilation, see table
"Ventilation modes and effective parameters"
starting on page 260.
