Do the Twist (Again)
The Essentials
It’s the small details that can unravel you. You’ve delivered the tube. The cords are behind you. The weight of the moment starts to lift. You reach for the syringe, inject 8 cc of air into the cuff… and it won’t stay inflated.
Now what? The Luer lock is one of the most ubiquitous connectors in modern medicine. It lives on syringes, IV tubing, arterial lines, and airway devices. Most of us have twisted one into place thousands of times without a second thought.
And that’s exactly the problem. Because it feels ordinary, we rarely teach it deliberately. We assume everyone knows. We assume it’s intuitive. But if you’ve never actually used one, it isn’t. And the worst time to figure it out is during a high-stakes intubation, surrounded by colleagues who just watched you perform smoothly, only to see you stumble over something that looks simple.
This is not where you want to fumble. If you’re unfamiliar with inflating and securing an endotracheal tube cuff with a luer lock syringe, this is where you learn it—calmly, deliberately, and without the spotlight on you.
