Evaqua™ 2 technology
The circuits incorporate Evaqua 2 technology, which eliminates the need for water traps by enabling excess humidity to diffuse through the circuit wall before it condenses. The Evaqua 2 expiratory tube of the breathing circuit is made from a material containing millions of permeable cells.
Water vapor diffuses through the permeable membrane to the outside of the tube. As there is less condensate collecting in the tube, circuit breaks can be minimized and the breathing circuit can remain a closed system. The Evaqua 2 tube wall is made up of many layers, making it robust and resistant to kinking and damage.
With conventional water-trap circuits, condensate can form in the expiratory limb where humidity in the gas flow touches cooler surfaces along the gas path. Evaqua 2 technology allows water vapor to diffuse through the expiratory limb wall before it has an opportunity to condense into liquid water within the circuit limb or the ventilator (neonatal ventilator or ventilator with neonatal modes).
