Previous blog posts have mainly discussed the theory behind jet ventilation, particularly Superimposed High Frequency Jet Ventilation (SHFJV), the form of jetting possible with the TwinStream. In this blog you can read more about the application methods without the use of a catheter. Jet ventilation with a catheter will be discussed in a subsequent blog.
Jet ventilation via the laryngoscope
The most commonly used ventilation method with the TwinStream is jetting via a laryngoscope. The manufacturer of the TwinStream can adapt commonly used ENT laryngoscopes for SHFJV. This allows the ENT surgeon to operate in a familiar manner with completely free visibility, while the anesthesiologist regulates oxygenation and CO2 removal via Bi-level jet ventilation. This also makes long-term procedures feasible.
During these procedures, the ventilation air can be heated and humidified via a humidifier. This prevents cooling and dehydration of the mucous membranes, which is especially important for procedures lasting longer than 30 minutes.
Jet ventilation via the rigid bronchoscope
In other countries, jet ventilation via the rigid bronchoscope is widely used. In the Netherlands, this application is less common. Nevertheless, SHFJV is ideally suited for, for example, placing bronchus stents or debulking procedures.
Various bronchoscopes are suitable for use with the TwinStream. During the procedure, the patient remains safely ventilated with Bi-level jet ventilation, which ensures good oxygenation and CO2 removal.
Jet ventilation via the Jet-converter
The Jet-converter was initially developed for thoracic surgery with a double-lumen tube, for example, in lung surgery where the lung to be operated on must be still. By ventilating this lung via jet ventilation, shunting is greatly reduced.
In addition, the Jet-converter is used for flexible bronchoscopy and ventilation with a laryngeal mask. The Jet-converter also offers a solution for radiological interventions where thoracic movements are undesirable.
