    A novel percutaneous transtracheal ventilation (PTV) device, assembled from inexpensive supplies, effectively resuscitated dogs with airway obstruction. This life-saving technique offers an alternative when standard methods fail.

    Area of Science:

    • Emergency Medicine
    • Respiratory Physiology
    • Medical Device Innovation

    Background:

    • Acute upper airway obstruction presents a critical challenge in emergency medicine.
    • Established methods for airway management may be unavailable or unsuccessful in severe cases.
    • Percutaneous transtracheal ventilation (PTV) is a potential resuscitation technique.

    Purpose of the Study:

    • To describe a readily assembled device for percutaneous transtracheal ventilation (PTV).
    • To evaluate the efficacy of this PTV device in a canine model.
    • To provide an alternative airway management strategy for acute upper airway obstruction.

    Main Methods:

    • A PTV device was constructed using common, inexpensive hospital supplies.
    • The device was tested in a canine model simulating acute upper airway obstruction.

  • Oxygen was delivered at moderate pressures and flow rates via the PTV catheter.

    • Main Results:

    • The PTV device facilitated effective ventilation in dogs.
    • Arterial oxygen levels (PaO2) exceeded 300 torr.
    • Arterial carbon dioxide levels (PaCO2) were maintained around 40 torr.

    Conclusions:

    • A rapidly assembled PTV device using available supplies is feasible.
    • This PTV method can achieve adequate oxygenation and ventilation.
    • Percutaneous transtracheal ventilation serves as a vital life-saving intervention when conventional airways fail.
