Paxian et al. Transtracheal ventilation with a novel ejector-based device (Ventrain) in open, partly obstructed, or totally closed upper airways in pigs. Br J Anaesth 2015

Dr. Paxian and colleagues demonstrated that Ventrain can ensure sufficient oxygenation and ventilation through a small-bore transtracheal catheter in live pigs when the airway is open, partly obstructed, or completely closed. Additionally, the minute ventilation and avoidance of high airway pressures were superior in comparison with traditional hand-triggered jet ventilation, particularly in the event of complete upper airway obstruction.
