HALO: EM

HALO is a bedside reference for High-Acuity Low-Occurrence emergencies — the procedures you rarely perform, and cannot afford to get wrong when you do. It is built for one moment: you are at the bedside, the patient is deteriorating, and you have less than a minute to remember the steps. WHAT'S INSIDE • 70 procedure and management cards, from cricothyroidotomy and resuscitative hysterotomy to paracentesis, lumbar puncture and lateral canthotomy • 25 core ED procedures — simple and complex lacerations, nerve blocks, arthrocentesis, abscess drainage, joint reductions, procedural sedation and more • A casting and immobilisation reference — find the injury, see the immobilisation most commonly used for it plus a reasonable alternative, then the technique and a video showing how to apply it • Decision algorithms you can walk step by step • "Still failing — what am I missing?" sections for when the protocol has run out and the patient is still crashing BUILT FOR THE BEDSIDE • Red ring = act in seconds. Amber ring = act in minutes. • Steps, not paragraphs. Doses where you need them. • Works completely offline — no signal required, which is exactly when you need it • Free. No accounts, no ads, no subscription, nothing to unlock. WHO IT'S FOR Physicians, residents and other qualified clinicians. HALO is a reference and educational tool. It does not diagnose, does not make recommendations for an individual patient, and does not replace clinical judgement, local protocols or specialist consultation. Clinical responsibility remains with the treating clinician.
