Arterial Line Placement
Chapter 5 covers the fundamentals and techniques of arterial line placement, including the palpation technique, ultrasound guided arterial line placement, and the cutdown technique. Arterial line placement involves inserting a catheter into a peripheral artery, most commonly the radial or femoral artery. Arterial lines provide beat-to-beat blood pressure monitoring as well as a readily available means of obtaining blood samples to check arterial blood gas measurements and other labs. Cannulation of the ulnar, brachial, axillary, posterior tibial, dorsalis pedis, and umbilical (in neonates) arteries has also been described, although these sites may be higher risk. Although the techniques described in this chapter focus on the radial, femoral, and posterior tibial approaches, many of the general principles apply to the other arteries as well.
