Zeroing a transducer on an external ventricular drain: A search for evidence-based practice

Event Details

Course introduction:
External ventricular drains (EVDs) are commonly used in brain-injured patients to diagnose intracranial hypertension. The accuracy of the intracranial pressure reading is dependent on zeroing the external transducer to air. Recent concern about zeroing techniques has been identified in the neuroscience community. The open method requires removing the nonvented cap, and the closed method requires zeroing through the filter at the top of the burette. This webinar will explore whether zeroing a transducer on an EVD through the filter of the burette provides the same baseline zero as opening the transducer to air.

Course Objectives:

    • Contrast two methods for zeroing a transducer on an external ventricular drain
    • Appraise current literature related to zeroing a transducer
    • Explain the role of medical device instructions for use
    • Review future research opportunities
