Evaluating hands-free carotid Doppler ultrasound for real-time return of spontaneous circulation detection in in-hospital cardiac arrest: a multicenter randomized controlled study

ResuscitationPublished

  • multicenter randomized controlled study
  • five affiliated teaching hospitals of medical universities

Authors' conclusion

The CADFlow hands-free carotid Doppler ultrasound system improves ROSC detection, shortens assessment time, and provides real-time feedback for CPR quality optimisation.
