Wahlen et al. Ventrain: from theory to practice. Bridging until re-tracheostomy BJM Case Rep 2017

Dr Wahlen and colleagues described a case in which Ventrain in combination with a tube exchanger was used to ventilate a patient with life-threatening tracheal stenosis. After a failed initial intubation with an endotracheal tube (ID 5.0 mm) the tube exchanger was inserted allowing allowed adequate ventilation with Ventrain until surgical tracheostomy was performed. Hemodynamic stability indicated that the active expiration induced by Ventrain prevented intrapulmonary pressure build-up by air trapping and subsequent barotrauma, which may be observed during traditional jet ventilation in a similar situation.
