In this episode you will learn: - A butterfly (winged) set is the preferred device for patients with small, fragile, or difficult-to-access veins, such as in pediatric and geriatric draws. - A discard tube is mandatory before collecting a light blue top (coagulation) tube to purge the air from the set's tubing. - Failure to use a discard tube will cause the coagulation tube to underfill, altering the 9:1 blood-to-additive ratio and invalidating test results. - The risk of hemolysis increases if a syringe plunger is pulled back too forcefully, due to the pressure exerted on red blood cells passing through the small-gauge needle. - The typical needle gauge for a butterfly set is 23G, which results in a slower blood flow compared to a standard straight needle.
