Technique
- Preparation
- Fully extend the neck
- Perform the laryngeal handshake to identify the CTM
- Consider ultrasound to identify trachea, CTM
Should not delay procedure in emergency situation.
- Insertion
- Infiltrate the neck with 1-2ml of 2% lignocaine in an awake patient
- Connect the cannula to a saline-filled syringe
- Insert the cannula through skin towards the cricothyroid membrane, aspirating as the needle is advanced

- Position is confirmed via capnography
- At this point jet ventilation can be performed if required
- Post-procedure
- Cannula can be left in situ to use as a rescue device if required
