Every crew carries a cric kit, and most medics have practiced the cut. Far fewer have practiced the decision.
The hardest part of a cric is deciding to do one
Most paramedics can walk you through a surgical cricothyrotomy. Scalpel, finger, bougie, tube. The steps are simple and they train well on a manikin. What does not train well is the moment you realize the airway you are fighting is never going to work and you need to stop trying.
That moment is where patients are lost. Every minute spent on one more laryngoscopy attempt or one more supraglottic airway is a minute of hypoxia the patient does not get back.
Two scenarios, two clocks
Picture two calls. Both are teaching scenarios, not real patients.
Scenario one: a medical arrest. A patient is found down at a dialysis center with an unknown last treatment. Compressions are running and the crew is treating a likely hyperkalemic arrest. Her tongue looks big, but that gets chalked up to anatomy. When the airway comes up, the mask will not move the chest, the view shows swollen tissue and no cords, and the supraglottic airway will not seal. Every lifeline is failing, which makes this a can't intubate, can't oxygenate (CICO) airway. Each failure still feels like a technique problem, so the crew tries again.
Scenario two: penetrating neck trauma. A patient has a gunshot wound to the front of the neck. The jaw is fractured, the mouth is full of blood, bag ventilation leaks out through the wound, and suction cannot keep up. The patient goes apneic. Nobody on scene doubts this airway is failing, and the decision to cut comes fast.
| Scenario one | Scenario two | |
|---|---|---|
| What the patient looks like | A routine arrest airway | An obviously destroyed airway |
| What the failure looks like | Quiet. Devices just do not work | Loud. Blood, air leaks, broken anatomy |
| Main risk | Delay while the crew keeps trying | Low risk of hesitation |
The cric is the same procedure in both. What changes is how obvious the failure is. Quiet failures are the dangerous ones.
Why quiet failures get missed
Scenario one is a setup for premature closure: locking onto a diagnosis early and reading every new finding through it. A patient down at dialysis practically announces hyperkalemia. Treating that quickly is not wrong. The problem is the momentum that comes with it.
Once a crew is moving down one track, each step makes the next one feel obvious. No cords on the first look, so the medic assumes it is a technique problem and tries again. The bougie finds nothing, so the next move is a supraglottic airway. Each step is reasonable in isolation. Together they burn minutes the patient does not have.
Think of it like driving with GPS. Miss a turn and the app reroutes you right away. Humans under stress do the opposite. We keep driving and explain away the signs that we are lost.
One habit helps a lot:
- Do a solid assessment and commit to a working diagnosis.
- Start treating it.
- Immediately try to prove yourself wrong by asking what else this could be.
- If the evidence points elsewhere, drop the first idea fast.
Set a tripwire
Cricothyrotomy gets called a once-in-a-career procedure. That framing quietly works against you. If you believe you will probably never cut a neck, every failed attempt gets explained away as something else, and the scalpel stays in the kit.
A better approach is to set a tripwire: a decision you make before the call about exactly what will make you cut.
- Define the pattern ahead of time. For the airway, the classic trigger is a best effort that fails at all three lifelines: intubation, mask ventilation, and a supraglottic airway. A best effort means an optimized attempt, with better positioning, adjuncts, or different equipment, or a capped number of tries. If the anatomy is obviously destroyed, many protocols support going surgical sooner.
- Pre-commit the action. When the tripwire is crossed, the response is already decided. No discussion. A cric.
Pilots work the same way. They do not brainstorm when an engine quits on takeoff. The response is decided and rehearsed long before it is ever needed.
CICO Decision Drill
The clock runs at three times real speed while you think, and every airway move costs time. Run Call 1 once with the triggers hidden, then again with Show my triggers on, and compare your decision lag.
Your moves
Each move costs call time. Optimized moves are what count as a best effort. Repeat anything as often as you like.
Your tripwire
Decided before the call: a lifeline fails after an optimized attempt fails, or after 3 attempts. When all three fail, you cut. No debate.

- Can't oxygenate by mask0/3
- Can't oxygenate by SGA0/3
Obvious airway destruction: many protocols support going straight to a surgical airway here.
Debrief
Build your own tripwire
- Write your triggers down. Decide as a crew what failed oxygenation looks like. Put it on paper so nobody has to invent it under stress.
- Say the plan out loud before you start. Plan A, B, C, and the cric. When everyone has heard it, anyone on the crew can call the switch.
- Open the kit early. If the airway looks difficult, open the cric kit before your first attempt, not after your third.
- Rehearse the decision, not just the cut. Run scenarios where the hard part is recognizing the moment.
- Debrief the clock. After any difficult airway, ask how long it took to recognize the problem and what kept you from seeing it sooner.
The drill is a teaching simulation for decision making, not a skills trainer. Times and vital sign trends are simplified estimates. Follow your agency's protocols and medical direction. Cricothyrotomy scope of practice varies by state and agency.
