| Step | Tissue type | Action and Fidelity type | Antiskills to avoid |
|---|---|---|---|
| Visually identify skin distention indicating a vein | Skin, vein, subcutaneous fat | Visual fidelity for identification of landmarks | Veins too easily seen through pale skin on a trainer, no training on different skin types |
| Palpate vein to verify, clean and prep skin with antiseptic | Skin, vein, subcutaneous fat | Tactile fidelity to palpation | Vein too easily felt, learner lost when encountering difficult to palpate veins |
| Placing light tension on the skin with your non-dominant hand, hold the needle bevel up and a 10-30 degree angle in your dominant hand and insert through the skin into the vein until you see the flash of blood return in the chamber | Skin, vein, subcutaneous fat, blood | Toughness to needle piercing (skin and vein), mobility of vein with respect to the skin, appropriately thin wall to have a large enough lumen, viscosity of blood, visual fidelity of blood | Vein or skin too hard to puncture, tissue behind vein too firm so “through and through” piercings don’t happen even with bad technique. Vein rigid with no mobility or rolling. Lumen too small or too large. All can lead to aggressive, rough or poorly angled needles |
| Decrease angle to parallel and advance 2-4mm | Vein | Toughness to needle piercing | Too soft, and the needle won’t advance without piercing the vein, too hard, and the advance can’t fail, leads to rough advancing |
| Slide the catheter over the needle and into the vein | Vein | Intubation of a lumen–resistance fidelity | Catheter must be able to stretch entry point and slide without inappropriate friction to prevent learner practicing overly rough insertions |
| Remove needle and attach IV set | Vein, skin and blood | Retention of the catheter–stickiness fidelity, blood viscosity and pressure | Catheter can’t slide out too easily, and blood should flow if needle removed, or learner will not practice rapid attachment of IV set. |
