Video Laryngoscopy in the Field
Objective: Use video laryngoscopy as Plan A when trained and authorized — without abandoning BVM, bougie, and a spoken Plan B.
Why This Is Hard
The screen looks great and the SpO₂ is falling because nobody is bagging. DAS and ASA difficult-airway teaching: limit attempts, re-oxygenate, and do not keep doing the same failed move. Video is a tool. The truck is still a bathroom floor.
- Preoxygenate and position first. The camera does not fix a flexed neck.
- Fog, blood, and sunlight wash out the screen — have suction and a DL blade ready.
- You still confirm with continuous waveform capnography, not a pretty still image.
Field Rules (Education)
- Watch the tube pass the cords on the screen (or the eye), then look in the mouth as you withdraw so you did not intubate the piriform sinus.
- Hyperangulated vs standard geometry: they do not take the same stylet. Use the stylet your training and device require.
- Failed view: suction, position, bougie, different blade, SGA, or stop and oxygenate. AHA 2025 ALS: an SGA is an acceptable advanced airway in adult arrest.
- Do not stare: if SpO₂ is falling, come out and bag. The screen is not worth a hypoxic arrest.
Field Pitfalls
- Three VL looks with no BVM in between.
- Calling the tube good because “I saw rings” with a flat EtCO₂.
- No backup blade because “we only carry video now.”
Practice
60-second drill
Partner: (1) clean VL view, tube passed, no waveform; (2) blood on the lens, SpO₂ 82%; (3) arrest, VL not turning on. Next action in five words.
