ECC Defibrillation & Airway Management 2

Question 1

During an AED analysis, a bystander accidentally touches the patient. What is the most likely consequence?

Accepted Answer

The bystander may receive part of the shock energy

Answer

Contact with the patient during AED analysis or shock delivery can result in the bystander receiving a portion of the electrical discharge.

Question 2

When using a bag-mask device for a patient with suspected cervical spine injury, which airway maneuver is preferred?

Accepted Answer

Jaw thrust without head tilt

Answer

The jaw thrust maneuver opens the airway without moving the cervical spine, making it the preferred technique in suspected spinal injury.

Question 3

What is the recommended energy dose for the SECOND defibrillation attempt with a biphasic AED when the first shock was delivered at 200 J?

Accepted Answer

200 J or higher per manufacturer

Answer

For subsequent biphasic shocks, the same or higher energy level (per manufacturer specification) is recommended, typically ≥200 J.

Question 4

Which finding on end-tidal CO2 (ETCO2) monitoring during CPR suggests the patient may have achieved ROSC?

Accepted Answer

ETCO2 suddenly rises above 40 mmHg

Answer

A sudden sustained rise in ETCO2 to ≥40 mmHg during CPR is a strong indicator of return of spontaneous circulation.

Question 5

For an unresponsive adult in VF, how long should a single defibrillation attempt (shock + CPR) cycle last before re-analyzing rhythm?

Accepted Answer

2 minutes of CPR then re-analyze

Answer

After each defibrillation attempt, 2 minutes (approximately 5 cycles) of high-quality CPR should be performed before rhythm re-analysis.
