Ventilation mode transition
Ventilation settings selectable though the quick keys and More
Settings are set to the factory default settings at start up of the
system and at the end of each case. The ventilation settings remain
at the factory default until changed by the user. If a ventilation setting
is changed, the new setting remains active in all applicable modes
until the setting is changed again. Exceptions include:
•
For modes that use RR 4 to 100, the RR transfers to the new
mode at the set RR or 60 whichever is smaller. For example, if
the mode in use has a RR of 75 and the new mode does not
support a RR of 75, the RR is set to 60.
• For modes that use RR 2 to 60, the RR does not transfer to
modes that use RR 4 to 100. The RR is set to the factory default
or the last set if previously used during the case. For example, if
during the first case the RR (2 to 60) is set to 2 and the new
mode uses RR 4 to 100, the RR is set to the factory default.
• For modes that use I:E, when transferring to a mode that uses
Tinsp, the Tinsp is set to a calculation of I:E or 5 seconds
whichever is lower.
• For CPAP + PSV mode, Psupport and Pinsp settings are linked
during the patient case. When the Psupport setting is changed,
the Pinsp setting changes to the same value. The Pinsp setting
shows in the ventilation mode information above the ventilator
settings. To break the link during a case, change the Pinsp
setting using the Pinsp key.
