5. Instruccions de funcionament
5.1 Encès/Apagat
- To power on the system, press the green power switch on the pump unit.
- To power off, press the power switch again.
5.2 Modes de teràpia
The Domus 3 offers two therapy modes:
- Mode alternatiu: This mode cyclically inflates and deflates individual air cells to redistribute pressure points, aiding in pressure injury prevention and treatment. This is the primary therapeutic mode.
- Mode estàtic: This mode maintains a constant, stable surface pressure across the entire mattress. It is suitable for general use when alternating pressure is not required or desired.
Refer to the pump unit's controls to select the desired therapy mode.

Figura 5.1: Alternating Pressure Cycle. This diagram shows a human figure lying on the mattress, with an illustration of the alternating pressure cycle. Blue blocks represent inflated air cells, and arrows indicate the cyclical inflation and deflation pattern designed to redistribute pressure and prevent injury.
5.3 Pressure Adjustment (Firmness)
The pump unit features a variable pressure setting with a weight indicator.
- Adjust the pressure knob on the pump unit according to the patient's weight and comfort preference.
- Higher weight settings will result in firmer mattress inflation.
- Always ensure the patient is comfortable and adequately supported.
5.4 Low Air Loss Function
Air cells 3 through 11 are designed with a low air loss feature. This function continuously ventilates air to wick moisture and heat away from the mattress surface, contributing to patient comfort and skin integrity. This operates automatically when the system is powered on.

6. Manteniment i cura
6.1 Cleaning the Mattress and Cover
- The Nylon/PU cover is water-resistant and vapor permeable. It can be wiped clean with a mild disinfectant solution.
- Ensure the cover is completely dry before re-use.
