In needle cricothyrotomy, which is a potential complication due to the narrow lumen leading to inadequate exhalation?

Limited exhalation from a needle cricothyrotomy stems from its very small lumen, which makes air escape during ventilation inefficient. When positive-pressure ventilation is used, air can become trapped and intrathoracic pressures rise, leading to barotrauma. The most likely manifestation is a pneumothorax, sometimes with subcutaneous emphysema as air escapes into tissues. Bleeding and infection are possible with airway procedures in general but aren’t driven by the narrow lumen’s effect on exhalation, so the complication tied to this mechanism is barotrauma/pneumothorax from over-inflation.
