Arterial lines & Waveforms
#hemodynamics #ICUEquipment #waveforms
Arterial lines are commonly used in the ICU for sampling arterial blood and for invasive hemodynamic monitoring. This ICU OnePager shows you how arterial lines work, teaches you how to troubleshoot them, and reviews some of the common (and not so common) diagnostic clues hidden in the arterial pressure waveform.
