2.0 PRODUCT OVERVIEW
The Sentry/ST Systems are microcontroller-based therapeutic Pressure
Redistribution Mattress Systems for patient weights up to 500 pounds/226
kilograms.
The Alternating Pressure feature provides pressure relief by sequentially
deflating and inflating alternate air cells on a timed interval. It is widely
recognized that constant pressure to a bony prominence is the leading cause of
skin breakdown. The movement of the air cells helps to alleviate these areas of
constant pressure and enhances circulation.
The Sentry/ST Mattress is equipped with side bolsters.
Sentry 1250/ST-1200 – Integrated only
Sentry/ST-1400 – Integrated and Raised
The Low Air Loss (LAL) feature is available on all Sentry/ST Systems; it delivers
a flow of air to the patient to aid in maintaining a temperature environment that
enhances pressure wound therapy.
Sentry1250/ST-1200 directs the flow through the mattress
Sentry/ST-1400 uses Micro-vent™ Technology to direct the flow
through the cover to the patient’s skin.
The electronic controller provides a real-time display of the air pressure for both
the inflated and deflated air cells. The deflated air cells provide pressure relief,
while the inflated air cells support the patient’s weight. The amount of pressure
needed to support a patient can be set automatically, based on the patient’s
weight, or can be set manually through custom configurations in Advanced
Settings.
All settings are stored in memory. If the power is interrupted, the controller
returns to the previous settings when the power returns, with the exception of
the Alarm Mute and keypad Lock functions.
IMPORTANT! The Sentry 1250/ST-1200 & Sentry/ST-1400 are all part of the
same product line. However, due to specific design functions, the components
are not interchangeable. Doing so may cause loss of functionality and/or
unwanted alarm conditions. To aid in differentiating between the two models,
each cover, mattress and controller has a label indicating the model. The zipper
on the mattress and cover is also color coded. The Sentry/ST-1400 zipper is
blue and the Sentry 1250/ST-1200 is black.
