AED (separate from the medical kit) Oxygen & Ambu bag Oral airways (intubation equipment varies by airline) IV supplies (limited fluids, but enough for medication administration) Medications: epinephrine, steroids, bronchodilators, benzodiazepines, antipsychotics, glucose agents, and more BP cuff (palpated pressures only\u2014too noisy to auscultate!) Pulse oximeter (remember: 93% can be normal) \ud83d\udce1 Ground-Based Medical Support Most airlines consult 24\/7 emergency physicians on the ground Volunteers don\u2019t make diversion decisions\u2014the captain does Diversions involve significant operational and logistical consequences In-flight volunteers are there to assess, stabilize, and communicate \ud83e\udec0 Cardiac Arrest at 36,000 Feet Move to a bulkhead\/galley if possible Call for additional medical volunteers Early AED use CPR until ROSC, exhaustion, or medical futility Diversion decisions are collaborative and situational \u2696\ufe0f The Legal Question Good Samaritan protections apply Act within scope No gross negligence or willful misconduct No one has ever been successfully sued for assisting with an in-flight medical emergency You are not responsible for diversion decisions \ud83d\udd4a\ufe0f When Death Occurs In Flight Resuscitation attempts may cease when appropriate Diversion is not automatic Flight crew are trained to manage these situations professionally and discreetly \ud83d\udd11 Key Takeaways You already have the skills. The environment is different\u2014but the fundamentals are the same. Recognizing sick vs. not sick is incredibly valuable. Most in-flight volunteer diagnoses are ultimately confirmed in hospital. About 60% of passengers improve with basic stabilization. You are protected when acting in good faith and within scope. If you\u2019ve ever hesitated to answer that overhead call, this episode may change your perspective. ","author_name":"Critical Levels","author_url":"http:\/\/www.criticallevels.ca","html":"
