Ventilation is an integral part of cardiopulmonary resuscitation (CPR). Early intubation is recommended not only for the sake of better ventilation but also to prevent aspiration since aspiration is a common occurrence during CPR. It probably not infrequently contributes to an unfavorable outcome. Endotracheal intubation is sometimes very difficult especially under field conditions. Cricothyroid membrane puncture or transtracheal puncture with a 14g or 16g catheter needle enables high frequency jet ventilation (HFJV) and can often be performed more easily than intubation.
