SGEM#306: Fire Brigade and the Staying Alive App for OHCAs in Paris

Date: October 21st, 2020 Guest Skeptic: Dr. Justin Morgenstern is an emergency physician, creator of the excellent #FOAMed project called First10EM.com and a member of the #SGEMHOP team.

Case: You are waiting in line for coffee, discussing the latest SGEM Hot Off the Press episode on twitter, when an alert pops up on your phone. It says that someone in the grocery store next door has suffered a cardiac arrest and needs your help. You remember installing this app at a conference last year, but this is the first time you have seen an alert. You abandon your coffee order and quickly head next-door, where you are able to start cardiopulmonary resuscitation (CPR) and direct a bystander to find the store’s automated external defibrillator (AED) while waiting for emergency medical services (EMS) to arrive. After the paramedics take over, you wonder about the evidence for this seemingly miraculous intervention. Background: Out of hospital cardiac arrest (OHCA) is something that we have covered many times on the SGEM. * SGEM#64: Classic EM Papers (OPALS Study) * SGEM#136: CPR – Man or Machine? * SGEM#143: Call Me Maybe for Bystander CPR * SGEM#152: Movin’ on Up – Higher Floors, Lower Survival for OHCA * SGEM#162: Not Stayin’ Alive More Often with Amiodarone or Lidocaine in OHCA * SGEM#189: Bring Me to Life in OHCA * SGEM#231: You’re So Vein – IO vs. IV Access for OHCA * SGEM#238: The Epi Don’t Work for OHCA * SGEM#247: Supraglottic Airways Gonna Save You for an OHCA? * SGEM#275: 10th Avenue Freeze Out – Therapeutic Hypothermia after Non-Shockable Cardiac Arrest The American Heart Association promotes the “Chain-of-Survival”. There are five steps in the Chain-of-Survival for OHCA: * Step One – Recognition and activation of the emergency response system * Step Two – Immediate high-quality cardiopulmonary resuscitation * Step Three – Rapid defibrillation * Step Four – Basic and advanced emergency medical services * Step Five – Advanced life support and post arrest care Bystander CPR and early defibrillation are key components of the out of hospital cardiac arrest chain of survival. Unfortunately, most patients don’t receive these crucial interventions. Many people are trained in CPR but never use their skills, because it is unlikely that they will happen to be in exactly the right place at the right time.
