A modified, simple device for the emergency administration of percutaneous transtracheal ventilation

Abstract

Studies of percutaneous transtracheal ventilation with intermittent jets of oxygen under high pressure have demonstrated a tendency toward carbon dioxide retention and poor alveolar washout. A modification of the percutaneous transtracheal ventilation fevice to include an expiratory phase improves pulmonary gas exchange and minimizes the possibility of CO2 retention. The most common complication is subcutaneous emphysema caused by incorrect catheter placement. Although endotracheal intubation is unquestionably the treatment of choice, percutaneous transtracheal ventilation does offer a viable alternative when intubation cannot be rapidly accomplished.
