Emergency situations without the need of surgical procedure
Ventrain is the solution in life-threatening situations to establish rapid re-oxygenation without the need of a surgical procedure. Ventrain contains the patented EVA® (Expiratory Ventilation Assistance) technology, applying gas to the lungs with a constant flow and actively removing it. This makes Ventrain the first ventilation device to enable complete and safe ventilation through a small bore lumen in cases involving a fully or partially obstructed upper airway.
There are several advantages of expiration by suction during emergency situations:
- enables minimal invasive ventilation through a small bore tube of <3 mm ID;
- provides full ventilation: oxygenation and CO2 removal;
- achieves a minute volume up to 7 L/min;
- Makes side-stream capnometry possible (this functionality is not available in the USA).
Adults and pediatrics in emergency situations
In the case of a critical, but not fully obstructed, airway, Ventrain can also be used in combination with a small bore endotracheal tube (ID 2-3 mm), e.g. as an intubating introducer or tube exchange catheter. By changing the flow and/or inspiration and expiration time, the tidal volume can be adjusted to the characteristics of the procedure and patient e.g. difficult airway situations in young children. Ventilation can then be achieved through a small bore pediatric exchange or intubation catheter.
This review by Dr. Doyle provides a nice overview of available literature regarding the Ventrain ventilation system. A short explanation of the physical principles underlying the functional concept of Ventrain is followed by a summary of bench and animal studies...
