[ References ](#references-heading) Chaos in a clinic code rarely comes from not knowing enough medicine. It comes from losing sequence. As of March 2026, the current AHA CPR/ECC standard is the **2025 guideline** set, and structured emergency care still rests on two linked frameworks: **ABCDE** for the critically ill patient and **BLS/ACLS/PALS algorithms** for the patient in arrest. [\[1\]](#cite-1 "Reference [1]") Start With ABCDE ---------------- Use **ABCDE** as a loop, not a checklist. Fix threats as you find them: open and clear the airway, support breathing with oxygen or bag-mask ventilation, treat circulatory failure, check glucose and neurologic status, then expose for trauma, rash, toxin clues, or hidden bleeding. Reassess after every intervention. In practice, this is what prevents you from intubating a profoundly hypoglycemic patient or chasing an ECG before fixing hypoxia. [\[2\]](#cite-2 "Reference [2]") Once the patient is unresponsive, not breathing normally, and you cannot definitely feel a pulse within 10 seconds, declare arrest and pivot to the algorithm. ABCDE tells you what is failing; BLS/ACLS tells you what happens next without delay. [\[3\]](#cite-3 "Reference [3]") Know When to Switch to BLS/ACLS/PALS ------------------------------------ For adults, BLS means immediate recognition, activation of the response system, high-quality CPR, ventilation, and early defibrillation. Adults with **signs of puberty** follow the adult pathway. High-quality adult CPR means depth **at least 2 inches**, rate **100 to 120/min**, minimal pauses, full recoil, and compressor changes about every 2 minutes. If an advanced airway is in place, give **1 breath every 6 seconds** with continuous compressions. In VF/pVT, shock early. In asystole/PEA, give epinephrine as soon as possible. **Board pitfall:** do not let airway attempts delay shocks or compressions. [\[3\]](#cite-3 "Reference [3]") ScenarioAdult defaultPediatric differenceCompression target≥2 in depth; 100-120/minAt least one-third chest depth; same rateVentilation30:2 without advanced airway; 1 breath every 6 sec with advanced airwaySingle rescuer 30:2; 2 rescuers prepuberty 15:2; advanced airway every 2-3 secRhythm prioritiesShock VF/pVT; epinephrine ASAP in asystole/PEASame rhythm logic, but respiratory failure is a common upstream causeBradycardiaTreat instability and reversible causesIf HR <60/min with poor perfusion despite oxygenation and ventilation, start CPR Keep those adult-pediatric differences straight; boards love them and teams miss them under stress. [\[4\]](#cite-4 "Reference [4]") Children are not just small adults. Most pediatric arrests follow **respiratory deterioration or shock**, so ventilation matters earlier. Compression rate stays **100 to 120/min**, but depth is **one-third of the chest**. Use **30:2** for a single rescuer, **15:2** for 2 rescuers in prepubertal children, and if an advanced airway is in place, ventilate every **2 to 3 seconds**. Classic exam trap: if the child has cardiopulmonary compromise and the heart rate stays **<60/min despite oxygenation and ventilation**, start CPR. Post-puberty, return to the adult algorithm. [\[5\]](#cite-5 "Reference [5]") Reversible Causes: Think in Parallel ------------------------------------ Prioritize reversible causes in parallel with CPR. Adult ACLS still centers on the familiar Hs and Ts: **hypovolemia, hypoxia, acidosis, hypo-/hyperkalemia, hypothermia, tension pneumothorax, tamponade, toxins, pulmonary thrombosis, and coronary thrombosis**. The pediatric cardiac arrest algorithm uses the same frame and explicitly adds **hypoglycemia**. In Family Medicine settings, the usual killers are common: hypoxia, hypovolemia, potassium problems, toxins, and tension pneumothorax. [\[4\]](#cite-4 "Reference [4]") > **Clinical Pearl:** Assign one person to the reversible-cause sweep during the first 2-minute cycle. Ask closed questions: hypoxia, potassium, toxins, tension, tamponade? Use POCUS only if it does **not** interrupt CPR. And if you are choosing between another airway attempt and uninterrupted compressions, choose perfusion. [\[6\]](#cite-6 "Reference [6]") Clinical Correlations in Family Medicine ---------------------------------------- This matters even more in Family Medicine, where the first team may be small and mixed-experience. If an adult collapses in urgent care, have one person run compressions and the AED/defibrillator while the leader names the branch point out loud: shockable or nonshockable, plus the likeliest reversible cause. If a wheezing child becomes bradycardic and mottled, do not anchor on the monitor—ventilate first. And if deterioration is obvious, call for higher-level help early; do not wait for the arrest you can already see coming. [\[4\]](#cite-4 "Reference [4]") Leading the First 10 Minutes ---------------------------- In the first 10 minutes, the leader’s job is tempo and prioritization, not procedures. Set a **2-minute cadence**, use the visible algorithm, assign roles, and demand closed-loop communication. AHA education guidance supports **cognitive aids** for healthcare professionals because they improve protocol adherence and may improve CPR quality. Capnography helps confirm airway placement, monitor CPR quality, and a sudden ETCO2 rise can signal ROSC. [\[7\]](#cite-7 "Reference [7]") Structured resuscitation reduces cognitive load and forces time-critical decisions in the right order: assess, intervene, reassess, escalate. That is what keeps an ordinary team effective when the room gets loud. [\[7\]](#cite-7 "Reference [7]") Key Takeaways ------------- - Use **ABCDE** for the sick patient, and switch immediately to an arrest algorithm when there is no normal breathing and no definite pulse within 10 seconds. [\[2\]](#cite-2 "Reference [2]") - Adult high-quality CPR means **≥2 inches**, **100-120/min**, minimal interruptions, and **1 breath every 6 seconds** once an advanced airway is placed. [\[4\]](#cite-4 "Reference [4]") - In children, arrest is often the end stage of **respiratory failure or shock**; with bradycardia and poor perfusion, ventilation comes first, and **HR <60/min despite oxygenation/ventilation means CPR**. [\[5\]](#cite-5 "Reference [5]") - Treat reversible causes in parallel with CPR; adult algorithms use the Hs and Ts, and pediatric cardiac arrest explicitly includes **hypoglycemia**. [\[4\]](#cite-4 "Reference [4]") - The leader owns rhythm, role clarity, and decision timing. Use cognitive aids and 2-minute cycles to keep the team synchronized. [\[7\]](#cite-7 "Reference [7]") Conclusion ---------- Master structured resuscitation the way you master any procedure: rehearse the sequence until it survives stress. In Family Medicine, structure is what turns a small team into a safe team. [\[1\]](#cite-1 "Reference [1]") References (10) ------------------- 1. 1.
