Curative Hybrid Very High Risk
Mattress
OPERATION
Working Principle
The dynamic mattress system consists of a dynamic air pump and an alternating air
mattress. The air mattress has two distinct airway chambers:
1. Group A Chambers
– Air tubes 2,4,6 & 8.
2. Group B Chambers
– Air tubes 1,3,5,7 & 9.
A and B chambers alternate inflating and deflating by using the pump connected. This air
alternating, mattress system enhances the blood circulation to treat and prevent pressure
ulcers, when part of a holistic care package.
Static Mode
When the pump is adjusted to the static mode, air chambers A & B are both fully inflated until
the maximum pump pressures are achieved. (Maximum pressures vary between different
pump styles) Static mode is used for seating or patient transfer.
Alternating Mode
When started, both chambers A & B are initially inflated to the maximum pump pressure
(Maximum pressures vary between different pump styles). Group A chambers deflate for 5
minutes followed by both A & B inflating for 1.5 minutes. This is followed by Group B chambers
deflating for 5 minutes. This is one complete cycle.
