Maneuvers (Optional); Inspiration Hold, Expiration Hold - Dräger Perseus A500 Instructions For Use Manual

Maneuvers (optional)

Perseus has various maneuvers for lung
recruitment. During a maneuver, various data
concerning the lung mechanics are displayed so
that the user can assess the progress of the
maneuver.
The reminder function (option) reminds the user to
perform a maneuver. A reminder is issued after the
first change to a ventilation mode with medium or
high breathing support and also at settable
intervals after the ending of a maneuver. The
Consider recruitment message is displayed in
the waveforms for flow and pressure.
The use of lung recruitment maneuvers is the sole
responsibility of the user.
Dräger recommends that the patient's
hemodynamics always be monitored while the
maneuvers are being performed.

This maneuver is available in the volume-
controlled modes, the pressure-controlled modes,
and in the PSV mode, and offers the following
