An External Ventricular Drain (EVD) is a temporary catheter placed into the lateral ventricle to: • Monitor intracranial pressure (ICP) • Drain cerebrospinal fluid (CSF) • Reduce elevated ICP Key educational points for bedside management: Leveling • Level the transducer to the tragus of the ear (approximates the foramen of Monro). • Re-level with any head-of-bed change or repositioning. • Incorrect leveling leads to over- or under-drainage. Zeroing • Zero per institutional protocol. • Ensure the
