Supraglottic Airways in the Field

Why This Matters

Supraglottic airways (SGAs) are not “fake tubes.” In many EMS systems they are primary or rescue advanced airways that can oxygenate faster than repeated failed laryngoscopy. They still require sizing, depth, seal, and continuous confirmation.

When They Fit (Education)

• Cardiac arrest pathways where protocol prefers rapid advanced airway.
• Failed intubation / difficult BVM rescue when authorized.
• Some systems use SGA as first-line for certain providers/scopes.
• Not a license to skip suction, positioning, or EtCO₂.

Street Sequence Themes

1. Size per manufacturer and training (weight/height cues as taught).
2. Prepare suction, O₂, and waveform adapter first.
3. Insert with technique from your training — do not invent angles under stress.
4. Inflate cuff if designed for it; confirm chest rise and waveform EtCO₂.
5. Secure well; reassess after every move — SGAs dislodge.

Failure Modes

• Wrong size, poor depth, leak, vomit, laryngospasm context, inadequate seal in trauma/anatomy.
• False reassurance without continuous capnography.
• Using SGA when complete obstruction needs different management.

Key Points for Paramedics

• SGA is still an advanced airway for monitoring standards in modern teaching — continuous waveform when available.
• Know your protocol: when to escalate from SGA to ETT or CICO pathway.
• Document size, time, confirmation method, and EtCO₂ trend.

Field Pitfalls

• Inserting without suction ready in a dirty airway.
• No recheck after packaging.
• Treating SGA as “set and forget.”

Practice

Skills bay: timed SGA insertion with partner calling EtCO₂ confirmation and a simulated displacement after a log-roll. Related: Capnography.
