MANUAL VENTILATION

Ventrain®

One ventilator, many options

Ventrain is a single-use hand-held ventilation device intended to be used for ventilation through a small bore lumen to manage and prevent difficult or challenging airway situations.

Based on a fundamentally new ventilation principle: Expiratory Ventilation Assistance (EVA®) (which is the basic form of FCV® as applied by Evone®, creates active expiration suction).

Ventrain supplies O2 during inspiration and actively removes the expiratory gases. This shortens expiration time, increases the achievable minute volume and reduces the risk on air trapping and associated risks on barotrauma and circulatory collapse, when compared to other small lumen ventilation techniques in obstructed airways (e.g. jet ventilation).

EVA® by Ventrain

Ventrain® in combination with transtracheal catheter Cricath® or endotracheal cuffed tube Tritube® re-establishes adequate oxygenation levels quickly as an I:E of 1:1 and a minute volumen of respectively 7-7.5 L/Min can be obtained. Depending on the situation both can be used in difficult airway situations.

Ventrain® allows adequate ventilation in any patient (pediatrics emergency only), in combination with any narrow bore lumen (e.g. airway exchange catheter, rigid bronchoscope, etc.) via any route of airway access (oral, nasal, FONA).

It is easy in use as inspiration, supplying O2 and expiration, removing CO2, are initiated by using just a thumb.

Ventury principle

The technology enables active inspiration by gas flow and active expiration by suction (Venturi principle)

The mechanism of EVA® is shown by the cross section of Ventrain:

  1. Inlet hose connection to hospital O2 gas flow
  2. Narrow diameter to increase gas velocity
  3. Outlet gas flow
  4. Connection to patient
  5. Equilibration

Active inspiration AND Expiration

The only requirement is O2 or a mix of O2/Air from a high-pressure gas source (3,5 – 5,0 bar, 100%), with a pressure compensated flow meter:

Medical oxygen cylinders with flow regulator. A full 2 liter cylinder generally contains 400 l oxygen (uncompressed); at a flow of 15 L/min this provides for 20 minutes of Ventrain ventilation.

Medical oxygen supply system with pressure compensated flow regulator with a maximum flow between 10 and 15 L/min.

* Do not connect Ventrain directly to the flow output
of an anesthesia machine; flow output may be too limited and the flow regulator may not be pressure compensated.

Emergency:

Ventrain® is the solution in life-threatening situations to establish rapid re-oxygenation via a small bore lumen. The type of lumen and route of airway access (oral, FONA by needle cricothryotomy or by scalpel bougie technique) is not of interest as long as the lumen has a Luer connector. The ventilation provided by Ventrain has several advantages: it enables minimal invasive ventilation through a small bore tube of < 3 mm ID, it provides full ventilation: oxygenation and CO2 removal and it allows side-stream capnometry.

Elective surgery:

Ventrain, in combination with Tritube, can especially be useful during ENT/laryngeal surgery. This combination offers several new surgical options for treatment. Our ventilation techniques FCV® and EVA®* enable full ventilation through small bore lumen, providing adequate ventilation even in cases involving critically obstructed airways. In comparison to jet ventilation, it strongly reduces the risk on barotrauma.

During upper airway surgery, ventilation may be challenging: A clear and hygienic surgical exposure is demanded and any potential sudden airway obstruction and aspiration needs to be handled. In combination with Ventrain as the ventilator, Tritube fulflls these needs. Tritube’s ultrathin OD of only 4.4 mm in combination with a sealed airway preventing turbulences of air nearby the surgical site, creates a large surgical exposure.

In case of Lung Isolation procedures Ventrain provides effective additional ventilation of the non-dependent lung in order to prevent or rapidly overcome cases of hypoxemia. The flow-based inspiration and suction-supported expiration enable inspiration and expiration at any speed desired with very small, but effective tidal volumes ensuring the non-dependent lung remains collapsed. Therefore, there is no delay or postponement of surgery. If required, the active expiration can also initiate a more effective and faster collapse.

Always observe the patient’s chest excursions closely during ventilation and adjust the time for inspiration and expiration where needed or use the equilibration position. In case of abdominal movement immediate re-access position of catheter and re-evaluate SO2 status.

Recommended catheters dimensions

Ventrain® is designed to be used in combination with recommend catheter dimensions (Table 1); Ventinova small lumen catheter (Cricath®), ultra thin endotracheal tube (Tritube®) or any narrow bore lumen (e.g. airway exchange catheter, rigid bronchoscope, etc.)

Tidal and minute volumes are depending on the flow meter settings, the inspiration time, expiration time and the patient characteristics (Table 2).

Table 2: Tidal volume at different inspiratory flow settings.

Table 1: Attainable minute volumes and proposed I:E ratios for recommended catheter dimensions in different situations.

Side stream capnometer:

Note that a reliable EtCO2 measurement requieres gas sampling during an equilibration phase and a sealed airway (inflate cuff).

The capnogram should only be used to check proper positioning of the catheter and/or to evaluate the relative trend in EtCO2 concentration (applicable for closed or obstructed airways, not for (half)-open airways).

  1. Perform capnography via the side port of Ventrain. A filter may be used to avoid contamination of the capnometer.
  2. Insufflate to aimed intratracheal Peak pressure.
  3. Start equilibration phase.
  4. Read CO2 value from curve when a plateau is nearly reached (taking approx. 5-8 seconds).
  5. Resume ventilation
