The Soiled Airway

11 min Airway & Breathing Skip to quiz

Objective: Clear a soiled airway with position and suction before a look, and treat oxygenation as the win — not a tube through vomit.

Why This Is Hard

Textbooks show clean cords. Porches show dinner. Oxygenation and ventilation come first. BVM (bag-valve-mask) or an SGA (supraglottic airway) can be the right tool. Taking a long look through a pool of vomit is how tubes go in the esophagus and sats fall. Suction is not optional. Position the head, empty the mouth, then decide.

On this truck
  • Wide-bore suction on and tested before the first look. Yankauer clogs. Have a plan for thick vomit.
  • Roll or turn the head if you can. Gravity is a suction device.
  • If you cannot see cords, you should not be pushing a tube. Suction, bag, SGA.
  • SALAD-style continuous suction (suction-assisted laryngoscopy and airway decontamination) is a training skill if your service teaches it. It is not a license to skip oxygen.

Street Sequence

  1. Open. Turn if you can. Suction the mouth until you see anatomy or the sat forces you to bag.
  2. Two-person BVM with an adjunct. If the mask is a lake, suction again. Do not just squeeze harder.
  3. If you need a definitive look: suction, then a short look, then re-oxygenate. Attempt limits still apply.
  4. An SGA that you can bag through in a dirty airway is a win. Confirm with waveform EtCO₂ (the CO₂ waveform on the monitor). See failed-oxygenation and SGA lessons.

Field Rules

  • Oxygenation first: BVM or SGA may be appropriate. The goal is oxygen and ventilation, not a trophy tube.
  • Suction until you can see: a look through vomit is a guess. Esophageal intubation is the complication you cannot afford.
  • Position: ear-to-sternal-notch still matters. A soiled airway plus a flexed neck is two problems.
  • Reconfirm after they vomit again: tubes displace. Waveform EtCO₂ is the continuous check.
Say out loud
  • Suction is on
  • I cannot see — bagging
  • SGA if the pool wins
  • Waveform after whatever we place

Field Pitfalls

  • Three looks through vomit with no suction.
  • A clogged Yankauer and no backup.
  • Calling the tube good because you “saw it pass” in a brown field.

Practice

60-second drill

Partner: unresponsive overdose, mouth full of vomit, sat 70%. First 20 seconds. Then: you placed an SGA and the sat is rising. What confirms it?
