From vasopressor support to anti-hypertensive drips, arterial lines allow for instant feedback on a patient’s hemodynamics. In cardiac arrest settings, arterial lines can be used to assess for the presence of a pulse and can help guide resuscitation. The radial artery is the most common location for arterial line placement because it is readily accessible and has a low complication rate. The femoral artery is also a common insertion site and is often the vessel of choice for severely hypotensive or coding patients because of its larger caliber. This post details each of these procedures.
