ObjectivePoint-of care-ultrasound (PoCUS) is useful in evaluating unstable emergency department patients. The portability of this technology increases its potential use in prehospital settings, including helicopter emergency medical services (HEMS) programs. Identifying useful applications may support implementing a PoCUS program that develops sonography skills for prehospital providers. The aim of this study was to determine the HEMS patient population that would benefit from prehospital PoCUS for hypotension and how commonly the extended focused assessment with sonography in trauma (E-FAST) for trauma patients or the rapid ultrasound in shock (RUSH) for medical patients could be used by HEMS.MethodsA retrospective chart review was performed over a 1-year period of adult patients transported by a midwestern HEMS system. Charts were reviewed for episodes of hypotension.ResultsThe chart review included 216 charts, of which 3 were excluded. Of the 213 cases, 100 were trauma patients, and 113 were medical patients. Of the trauma patients, 51% experienced hypotension, as did 73 of 113 medical patients.ConclusionFifty percent of HEMS patients may benefit from PoCUS to evaluate for hypotension in flight.Copyright © 2021 Air Medical Journal Associates.
