True regarding cardio pulmonary resuscitation is:
Answer is C (Adrenaline is given if cardioversion fails) During cardiopulmonary rescuscitation (CPR), administration of Adrenaline is recommended only after attempts at cardioversion fail. Adrenaline (Epinephrine) is given if cardioversion fails Cardioversion is a brief procedure where an electric shock is given to the hea to conve an abnormal hea rhythm back to a normal rhythm (Defibrillation) Cardioversion/Defibrillation is recommended as the immediate step during cardiopulmonary resuscitation. Adrenalene/Epinerphrine is recommended only after Jailed defibrillation/cardioversion 'Epinephrine 1 mg intravenously is given after failed defibrillation' Most common presentation on ECG is ventricular fibrillation (VF) and not Asystole (H17th/1708) `The most common electrical mechanism for true cardiac arrest is ventricular fibrillation (VF) Which is responsible for 65 to 80% of cardiac arrest Harrison 'Asystole, Pulseless Electrical Activity and Severe Bradyarrhythmias cause the remaining 20 to 30%' Calcium gluconate is not recommended for routine administration (H17th/1712) Intravenous calcium gluconate is no longer considered necessary or safe for routine administration It is now only recommended for ceain specific indications Indications for calcium gluconate administration Acute hyperkalemia (Known to be the triggering event for resistant VF) HypocakemiaQ Patients who have received toxic doses of calcium channel antagonisitsQ
Most common presentation in ECG is asystole
Compression to ventilation ratio is 5:1
Adrenaline is given if cardioversion fails
Calcium gluconate is given immediately
