ALS / CPR Flashcards
(18 cards)
What is the first step in the Adult Cardiac Arrest algorithm?
Confirm unresponsiveness and absent or abnormal breathing, then start CPR immediately.
What rhythms are considered shockable in cardiac arrest?
A: Ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT)
What is the immediate action for shockable rhythms during ALS?
A: Deliver one shock, then resume CPR for 2 minutes before reassessing rhythm.
What is the adrenaline dosing during cardiac arrest?
A: 1 mg IV/IO every 3-5 minutes during CPR.
When is amiodarone indicated in cardiac arrest?
A: After 3 shocks for persistent VF/pVT (300 mg IV/IO), then 150 mg after 5 shocks if needed.
What are the 4 H’s reversible causes in cardiac arrest?
A: Hypoxia, Hypovolaemia, Hypo-/Hyperkalaemia (and other metabolic disturbances), Hypothermia.
What are the 4 T’s reversible causes in cardiac arrest?
A: Tension pneumothorax, Tamponade (cardiac), Toxins, Thrombosis (pulmonary or coronary).
How do you manage bradycardia with a pulse if the patient is unstable?
A: Give atropine 500 mcg IV, repeat every 3-5 min up to 3 mg; prepare for transcutaneous pacing if atropine ineffective.
What is the first-line drug for unstable bradycardia?
A: Atropine 500 micrograms IV.
What is the initial management for unstable tachycardia with a pulse?
A: Immediate synchronized cardioversion.
How stable SVT managed?
A: Vagal maneuvers; adenosine (6, 12, 18), verapamil/beta blocker, Syn DC shock
What is the fluid of choice and typical volume for resuscitation in cardiac arrest?
A: Crystalloid fluids, 500–1000 mL for adults; 10 mL/kg for children.
What energy dose is recommended for the first biphasic defibrillation shock?
A: 150–200 Joules (depending on device).
What oxygen saturation target is recommended post-resuscitation?
A: 94–98%.
