• Smart first-responder alerting vs fixed-radius alerts in OHCA

  Journal of the American Heart Association · RCT · Hypothesis-generating

  A three-arm German RCT across 823 activations found smartphone smart-alerting got community first responders to OHCA before EMS in 58% of missions — better than a 600 m fixed radius (31%) but no better than a 2500 m radius (57%).

• PEEP during CPR linked with more ROSC

  The American Journal of Emergency Medicine · Cohort · Hypothesis-generating

  A single-centre Belgian cohort of intubated OHCA patients managed by a physician-staffed team found mechanical ventilation with PEEP during CPR was associated with higher odds of ROSC (adjusted OR 1.58) than manual ventilation without PEEP.

• Ultrasound added to stroke scales for LVO triage

  Frontiers in Neurology · Other · Hypothesis-generating

  A German exploratory reanalysis of the 20-patient SONAS trial found portable non-imaging brain perfusion ultrasound combined with prehospital stroke scales sorted suspected stroke into likely-LVO, likely-non-LVO and unassessable groups better than either method alone.
