LOW AIR LOSS (All Sentry/ST Systems)
This key activates or deactivates the LAL feature. When activated, LAL is
shown on the display and a gentle diffused flow of air is delivered through
the LAL coverlet (Sentry/ST-1400), or the mattress (Sentry 1250/ST-
1200). The air will begin to flow only after the mattress has reached the set
pressure, either after initial installation or in any mode such as AP, Float,
or MAX. The air flow will also be temporarily interrupted while the raised
bolster is inflating.
THERAPY (Sentry/ST-1400 System)
This key selects the ALTERNATING PRESSURE RELIEF (AP) or AIR
FLOTATION (Flt) mode. The screen display toggles between Flt and AP.
NOTE! The Sentry 1250/ST-1200 has separate keys for these two
therapies.
FOWLER BOOST (All Sentry/ST Systems)
This key activates or deactivates the FOWLER BOOST (FB) mode. When
activated, FB is shown on the display and the set pressure in the mattress
is automatically increased by a set percentage. It is not available when the
system is in Maximum Inflate mode. The percentage of increase may be
modified by going to ADVANCED SETTINGS. (See Section 4.4.2)
This feature helps prevent a patient from “bottoming out” when he or she is
put into an inclined or “Fowler” position.
INFLATE BOLSTERS (Sentry/ST-1400 System)
This key inflates or deflates only the raised side bolsters. When activated,
Inf is shown on the display and the bolsters will take approximately (1)
minute to inflate.
