A Palpable Pulsatile Radial Arterial Line Insertion Simulator
Cannulation of the radial artery is a key procedure required for intensive care blood pressure monitoring. Medical students, residents, and critical care fellows alike often have exposure to this procedure during their intensive care rotations. Various methods exist regarding radial artery cannulation including ultrasound-guided and manual palpation-guided needle insertion. Unfortunately, simulation models for radial artery cannulation are somewhat lacking in regards to palpable pulsatile radial artery cannulation. Often, in order to have a robust palpable and durable model, the radial artery vessel itself is out of proportion to the typical human radial artery. Furthermore, educational simulators often lack arterial pressure simulation which is an important physiological indicator during radial artery cannulation. We describe the development of a palpable, pulsatile radial arterial line simulator at Western Michigan University Homer Stryker M.D. School of Medicine that is representative to vessel size and arterial pressure.
