Cardiac Emergency Protocols Flashcards

What is the correct compression-to-ventilation ratio for adult CPR according to DCAS protocols?

Answer: 30:2

DCAS follows international guidelines recommending a 30:2 compression-to-ventilation ratio for adult CPR, with compressions at a depth of 5-6 cm and a rate of 100-120 per minute.

What is the first shockable rhythm a DCAS paramedic should identify on a cardiac monitor?

Answer: Ventricular fibrillation (VF)

Ventricular fibrillation (VF) is a chaotic, disorganized cardiac rhythm that is shockable. Identifying VF quickly allows paramedics to deliver defibrillation, which is the primary treatment.

What is the recommended energy level for the first defibrillation shock in adult cardiac arrest using a biphasic defibrillator?

Answer: 120-200 joules depending on manufacturer

DCAS protocols align with international guidelines recommending initial biphasic defibrillation at the manufacturer's recommended dose, typically 120-200 joules for the first shock.

What is the STEMI protocol for DCAS paramedics?

Answer: Obtain 12-lead ECG, identify ST-elevation, administer aspirin, notify receiving cardiac catheterization center for direct transfer

DCAS STEMI protocol requires early 12-lead ECG acquisition, identification of ST-elevation, aspirin administration, and direct notification/transport to a PCI-capable hospital to minimize door-to-balloon time.

What is the role of adrenaline (epinephrine) in DCAS cardiac arrest protocols?

Answer: It is administered intravenously every 3-5 minutes during cardiac arrest to improve coronary and cerebral perfusion

Adrenaline 1mg IV is administered every 3-5 minutes during cardiac arrest to improve coronary and cerebral perfusion pressure through vasoconstriction, increasing the likelihood of return of spontaneous circulation.

What is the recommended duration of CPR before reassessing rhythm in DCAS protocols?

Answer: 2 minutes (5 cycles of 30:2)

DCAS protocols recommend 2 minutes of uninterrupted CPR (approximately 5 cycles of 30:2) before pausing briefly to reassess the cardiac rhythm and check for signs of return of spontaneous circulation.
