Vascular Module Step 18, Part 3 Central Vein Subclavian 1. Which of the following is the best method to assess the subclavian vein with ultrasound?* Start scan in transverse plane of vessels Place probe above the lateral clavicle and then slide caudally Limit the pressure on your probe to avoid collapsing the vein. All of the above 2. Which of the following interfere with finding the subclavian vein on ultrasound?* The pleura and air filled lung The clavicle The second rib The sternocleidomastoid muscle attachment 3.What is the preferred method of ultrasound guided subclavian vein access?* Transverse - because you can only see the vein in this view Transverse - because it has the least risk of pneumothorax or hemothorax Longitudinal - because decreased risk of perforating the posterior wall of the vein Longitudinal - because you can see both the artery and the vein in this view Ultrasound use in post catheter placement is:* A. Can be used to evaluate pleural line for pneumothorax B .Line best seen in longitudinal view C. Not recommended D. Both A and B 5.What is the expected depth when looking for subclavian vessels?* Less than 1 cm Between 2-3 cm Between 3-5
