Introducció
The Apex Medical Domus 3-5" Low Air Loss Alternating Overlay Pressure Mattress is designed to provide pressure redistribution and comfort for patients, particularly those at medium risk of pressure injury. This system features two therapy modes: alternating mode for dynamic pressure relief and static mode for a stable surface. Its ventilated low air loss function helps manage moisture and heat, contributing to patient comfort and reducing the risk of skin breakdown.

Components
The Apex Medical Domus 3-5" system includes the following main components:
- Pressure Mattress Overlay: Composed of 17 individual 5-inch air cells, with ventilated cells (3-11) for low air loss. Features a durable Nylon/PU cover with a zipper for easy removal.
- Variable Pressure Pump System: A compact and quiet pump unit that inflates and deflates the air cells, offering variable pressure settings and a weight indicator.
- Mànegues d'aire: Connect the pump to the mattress.
- CPR Strap: For rapid deflation in emergencies.

- Connecteu les mànegues d'aire: Connect the air hoses from the mattress to the corresponding ports on the pump unit. Ensure a secure and airtight connection.
- Connectar: Connecteu el cable d'alimentació de la bomba a una presa de corrent amb connexió a terra.
- Inflació inicial: Turn on the pump. The mattress will begin to inflate. Allow approximately 20-30 minutes for the mattress to fully inflate before placing a patient on it.

Instruccions de funcionament
Encès/Apagat
Locate the power switch on the pump unit. Flip the switch to the "ON" position to start the pump and inflate the mattress. Flip to "OFF" to turn off the unit.
Modes de teràpia
The Domus 3 offers two primary therapy modes:
- Mode alternatiu: This mode continuously inflates and deflates alternating air cells to redistribute pressure over time, preventing prolonged pressure on any single area. This is ideal for pressure injury prevention.
- Mode estàtic: In this mode, all air cells remain inflated to a constant pressure, providing a stable and firm surface. This mode is suitable for general use or when a stable surface is preferred.

Ajust de pressió
The pump unit features a variable pressure setting with a weight indicator. Adjust the pressure knob to select the appropriate firmness based on the patient's weight and comfort preference. Refer to the pump's display or markings for recommended settings.
Funció de baixa pèrdua d'aire
Air cells 3 through 11 are designed with a low air loss feature. This allows a small amount of air to escape through microscopic pores, wicking away moisture and heat from the patient's skin. This helps keep the patient comfortable and reduces the risk of skin maceration and shear forces.

Manteniment
Cleaning the Mattress Cover
The Nylon/PU cover is water-resistant and vapor permeable. It can be removed for cleaning. Unzip the cover completely and follow these instructions:
- Rentat a màquina: The cover can be machine washed. Use a mild detergent and cold water on a gentle cycle.

Neteja de la unitat de la bomba
Wipe the exterior of the pump unit with a damp cloth and a mild, non-abrasive cleaner. Do not immerse the pump in water or spray liquids directly onto it.
Air Cell Replacement
Each of the 17 air cells is individually removable and replaceable. If an air cell is damaged, disconnect the mattress from the pump, deflate the mattress, and carefully remove the damaged cell. Insert a new cell and re-inflate the mattress.
