Always start with CAB: Circulation (pulse check), Airway (open/clear), Breathing (look/listen/feel). High-quality CPR with minimal interruptions is key. Push hard, push fast (100-120/min), full recoil, switch every 2 minutes.
VF/VT: shock immediately, epinephrine 1mg IV q3-5min, amiodarone 300mg. Asystole/PEA: no shock, epinephrine 1mg IV q3-5min, treat reversible causes (5H's and 5T's). Bradycardia: atropine 0.5mg IV, consider pacing.
5H's: Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hypo/hyperkalemia, Hypothermia. 5T's: Toxins, Tamponade (cardiac), Tension pneumothorax, Thrombosis (pulmonary), Thrombosis (coronary). Address these during resuscitation.
Use closed-loop communication: "Give 1mg epinephrine IV" → "1mg epinephrine IV" → "Epinephrine given." Designate roles clearly. The team leader directs, others perform and confirm. Clear, loud, direct communication saves lives.
Consider termination after 20 minutes of high-quality CPR with no ROSC, if no reversible causes identified. Discuss code status early with families. Sometimes the most compassionate care is allowing natural death with comfort measures.
⚡ Remember: Stay calm, think systematically, and trust your training - you've got this!
