Recent JEMS Commentary Highlights the EMS Body‑Camera Debate A JEMS article explores how body‑worn cameras could affect EMS practice, weighing the benefits and challenges. Proponents note that cameras can provide clear documentation of patient interactions, defend against false complaints, and support quality assurance and training. Opponents raise concerns about HIPAA compliance, privacy of sensitive patient data, and operational impacts (e.g., distraction or data management burden). Students and future EMS leaders should understand both the legal/ethical implications and potential training advantages of emerging documentation tools. 🔗 https://www.jems.com/ems-management/to-cam-or-not-to-cam-the-great-ems-bodycam-debate/ JEMS EMS Training News 2025 AHA CPR/ECC Guideline Updates Spark Field Debate The 2025 American Heart Association (AHA) Guidelines for CPR and Emergency Cardiovascular Care emphasize on‑scene resuscitation and recommend prioritizing IV access over intraosseous (IO) when feasible. The updated recommendations also discuss cautious use of mechanical CPR devices (discouraging routine use) and put greater emphasis on quality compressions and defibrillation timing. These changes are generating discussion among paramedics about practical implementation, especially in rural or small‑crew settings where IO access and mechanical devices are frequently relied upon. For students, these evolving recommendations highlight the importance of staying current with national guidelines that directly influence prehospital cardiac arrest management and patient outcomes. 🔗 https://www.jems.com/patient-care/the-ems-avenger-on-the-2025-aha-guidelines/ JEMS

Two classic signs of increased ICP: - Hypertension - Bradycardia (Cushing’s reflex) Expected signs of brain herniation: - Unequal pupils - Posturing - Irregular respirations (Cheyne stokes or Biots/Ataxic) - Rapid decline in mental status Treatment for ICP (prehospital): - Hyperventilation ONLY if signs of herniation (get EtCO2 to 35-40) - Mannitol is NOT used in EMS unless critical care - 1g/kg over 10min for edema, not blood.
