Many EMS medical directors emphasize the goal of achieving ETI “first‐pass success.” While many prehospital EMS personnel define an ETI “attempt” as an effort to insert the endotracheal tube, national consensus guidelines suggest that an ETI “attempt” should be defined as an insertion of the laryngoscope blade to maintain consistency with airway management definitions used in other medical disciplines. A substantial portion of prehospital ETI require multiple attempts [33]. Studies of in‐hospital ETI efforts found that multiple ETI attempts were associated with increased risk of cardiac arrest [34]. Given the low probability of success following the second attempt, some EMS medical directors advocate limiting clinicians to two attempts, followed by immediate use of SGA.
