Best attempt face-mask ventilation Optimal position (ear > sternum) Head tilt chin lift jaw thrust 2 handed BMV Second person ventilates High fresh gas flows (O2 flush) Oro/Nasopharyngeal airway Cricoid off

Best attempt endotracheal intubation

Best person in room Best position (tragus >sternum) Best blade (e.g., videolaryngoscope) External laryngeal Manipulation (ELM) Bougie or stylet (only1 blind attempt) Consider muscle relaxant (if experienced) Cricoid off

Best attempt LMA ventilation Different type (e.g. Proseal™) Different size Insert under direct vision) Insertion with jaw thrust Pull tongue forward Cricoid off Consider muscle relaxant (if experienced)

There is no ideal number of attempts for face mask ventilation, endotracheal intubation or LMA ventilation.

A best attempt: • may involve >1 attempt• is unlikely to be beneficial

with >3 attempts

How many attempts?

Best attempt at:• Face-mask ventilation?• LMA ventilation? • Endotracheal intubation? AND

Oxygen saturations falling or persistently low?

Is this a CICO situation?
