The Alerta Ruby 2 is a premium alternating pressure replacement system for patients at very high risk of pressure ulcer development or with existing pressure damage requiring active treatment. The cell-on-cell design stacks two layers of air cells vertically, providing maximum immersion depth that fully envelopes bony prominences within the cell structure. With an 8-inch in-use height and static base section, the Ruby 2 delivers the deepest therapeutic surface in the Alerta overlay and replacement range. SensaCare Truflo Technology continuously auto-regulates inflation pressure based on real-time weight distribution monitoring.

Cell-on-cell replacement systems are indicated under NICE Guideline CG179 for very high-risk patients and those with existing Category 2 or higher pressure damage requiring active treatment. The dual-layer cell design exceeds the immersion depth of single-layer systems. CQC Regulation 12 requires that the most appropriate pressure care surface is provided based on the individual risk assessment. EPUAP/NPIAP/PPPIA guidelines recommend cell-on-cell systems for patients who have not responded to standard single-layer alternating surfaces.
What does cell-on-cell mean?
Cell-on-cell refers to the stacking of two layers of air cells vertically within the mattress. The lower cells provide a stable base while the upper cells deliver the alternating pressure cycle. This dual-layer structure doubles the immersion depth compared to single-layer systems, fully enveloping bony prominences within the air cell structure rather than resting on top of them.
When should the Ruby 2 be used instead of the Sapphire 2?
The Ruby 2 is indicated for very high-risk patients (Waterlow 20+) or those with existing pressure damage, providing 8-inch in-use height with cell-on-cell immersion. The Sapphire 2 is indicated for high-risk patients, providing 7-inch height with single-layer cells and self-inflating foam base. The clinical decision is based on individual risk assessment and wound staging.
