Product catalog summary

Introduction to EVAQUA Technology
EVAQUA is a pioneering breathing circuit technology designed to eliminate condensate in the expiratory limb using permeable membrane technology. This innovation allows water vapor to diffuse out before condensing into liquid, maintaining a closed system that requires minimal clinician intervention.

Key Features and Benefits

Eliminates mobile condensate in the expiratory limb, reducing the need for clinician intervention.
Prevents ventilation issues such as auto-PEEP and ventilator dysynchrony.
Eliminates the need for water traps and reduces condensate buildup in filters.
Maintains a closed system, reducing pathogen transfer risks and ensuring uninterrupted ventilation.

Performance Comparison
Data adapted from Deakins K et al. shows that conventional circuits accumulate significant condensate over 72 hours, whereas EVAQUA circuits show no condensate buildup.

How EVAQUA Works
Conventional circuits allow condensate formation when humid expiratory gas contacts cooler surfaces. EVAQUA technology uses a membrane permeable to water vapor, allowing humidity to diffuse out while maintaining a gas seal and blocking pathogens.

Conclusion
EVAQUA breathing circuits offer a maintenance-free, closed system that enhances patient safety and clinician efficiency by preventing condensate-related issues.

Catalog excerpts

Evaqua™ Breathing Circuits Your solution to expiratory condensate EVAQUA is the world’s first breathing circuit developed to eliminate expiratory limb condensate through the use of permeable membrane technology. EVAQUA technology allows water vapor to diffuse out through the expiratory limb wall before it has an opportunity to condense into liquid water within the circuit limb or the ventilator. The result is an easy-to-use system which is designed so that the breathing circuit can remain closed and free of clinician intervention. This, in turn, benefits both the patient and the clinician.

how does EVAQUA work? With conventional circuits, condensate can form inside the expiratory limb or ventilator when humidity in the expiratory gas flow touches cooler surfaces along the gas path. conventional breathing circuits Water Vapor (Humidity) EVAQUA allows the humidity in the expiratory limb to freely diffuse through the wall of the breathing circuit before it has an opportunity to condense and form into liquid water. Humidity passes through the wall of the expiratory limb via a membrane material that is permeable to water vapor. Due to the special nature of this material, the membrane...
