In percutaneous transtracheal ventilation, which ratio is used?

In percutaneous transtracheal ventilation, the timing of breaths is crucial because oxygen is delivered in brief inspiratory bursts through a transtracheal cannula while the patient exhales around the cannula. The expiratory phase must be longer to allow adequate exhalation and prevent air trapping or excessive pressures. A 1:4 inspiratory-to-expiratory ratio means a short inhalation followed by a longer exhalation, providing effective ventilation while giving the patient time to exhale through the cannula. Ratios with relatively longer inhalation or less exhalation disrupt ventilation safety and efficiency, making 1:4 the best choice.
