Used a 25g winged set with 12-inch tubing on a dehydrated LTC patient this morning and got sluggish flow after the first tube; swapping to a 23g finished two SSTs and a lavender, but I’m wary of hemolysis on potassium. What gauge and tubing length are you trusting for fragile veins with a Vacutainer holder right now, and any tiny tweaks to keep flow steady without fishing — I’m dialing in my kit and you’ve got this.
