Oxygen Delivery During Transtracheal Oxygenation

Abstract

This study confirms the absolute necessity of allowing gas exhalation between 2 insufflations and maintaining low respiratory rates during transtracheal oxygenation. In the case of total airway obstruction, the ENK may be less deleterious because it has a pressure release vent. Using a Manujet at lower driving pressures may decrease the risk of barotrauma and allow the safe use of higher respiratory rates.

Combining transtracheal catheter oxygenation and needle-based Seldinger cricothyrotomy into a single, sequential procedure

“…Appropriate ventilator parameters, specifically high-flow, high-concentration oxygenation with sufficient expiratory time, may reduce the complications associated with barotrauma caused by PTJV [13]. The importance of maintaining low respiratory rates, which allow for adequate gas expiration between subsequent insufflations, has been confirmed [14]. In properly selected cases, the use of PTJV appears not only justified but advantageous, providing oxygenation to patients without a definitive airway [15].…”

Percutaneous transtracheal ventilation in an obstructed airway model in post-apnoeic sheep

“…It delivers 250 ml O 2 s 21 through a 2 mm diameter catheter when set at 1 bar. 12 It is manually operated and has no expiratory or automatic shut off functions. It therefore has a low margin of safety in a completely obstructed airway.…”

“…It therefore has a low margin of safety in a completely obstructed airway. 12 The Ventrain w (Dolphys Medical B.V., Eindhoven, The Netherlands) is a hand-held single-use flow-regulated ventilation device designed for use with a 2 mm diameter transtracheal catheter in patients with complete airway obstruction. 15 16 The device contains a ventilation ejector positioned between an oxygen inlet and an exhaust channel (Fig.…”
