Airway Attempt Limits: Stop Digging
Objective: Treat each laryngoscopy as a scarce resource: oxygenate between looks, change one thing, and stop digging when the plan is failing.
Why This Is Hard
The sat is 70% and the crew is still “just going to try one more look.” DAS and Vortex teaching: repeated identical attempts steal oxygen and make CICO more likely. AHA airway teaching for cardiac arrest still wants high-quality CPR first — the tube is not the first intervention. On the street, ego and “I almost had it” are the usual reasons people keep digging.
- You have a clock (sat, EtCO₂, and how long since the last breath), not an OR full of extra blades.
- Each look is a dose of apnea. Count them out loud.
- SGA, two-person BVM, and a spoken CICO plan are exits — not admissions of failure.
Street Sequence
- Oxygenate. Two-person BVM or SGA with waveform if you have it. Do not start a look on a blue patient if you can still bag.
- First look: best position, best blade you are trained on, bougie if that is your system’s first-pass plan.
- Between looks: bag. Change one thing (position, blade, operator, SGA). Do not repeat the identical pass.
- If oxygenation is failing: declare CICO and move to your trained rescue (SGA then FONA per protocol). See the FONA lesson.
- In arrest: compressions and defibrillation beat a prolonged look. Airway is in parallel, not instead of CPR.
Field Rules (Education)
- Count the looks: many systems teach a hard stop at two or three attempts. Know yours. “One more” without a change is the same attempt twice.
- Change something: ear-to-sternal-notch, VL vs DL, bougie, smaller tube, different operator, or abandon the tube for an SGA.
- Oxygen is the product: a sat that is climbing with an SGA beats a pretty view you cannot pass.
- CICO is a sentence: “I cannot intubate, I cannot oxygenate — moving to rescue.” Say it before the last authorized look, not after the sat is 40%.
- This is look number __ — I am changing __
- Bag / SGA now — sat before the next look
- CICO: rescue plan is __
- In arrest: CPR continues during the look
Field Pitfalls
- Four identical DL attempts because “I saw the arytenoids.”
- No bagging between looks while someone hunts for a different blade in the jump bag.
- Calling for FONA only after the patient is already in PEA from hypoxia.
Practice
60-second drill
Partner: first look nothing, sat 82%. Name one change and the next 20 seconds of oxygenation. Then: third look still nothing, sat 70%. Say the CICO sentence.
