DCAS Cardiac Emergency Protocols

Question 1

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

Accepted Answer

30:2

Answer

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.

Question 2

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

Accepted Answer

Ventricular fibrillation (VF)

Answer

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.

Question 3

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

Accepted Answer

120-200 joules depending on manufacturer

Answer

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

Question 4

What is the STEMI protocol for DCAS paramedics?

Accepted Answer

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

Answer

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.

Question 5

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

Accepted Answer

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

Answer

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.
