Assessment of the Situation
Assessment of the Patient
Definitive Rescue Phase

Question 3

is a lightweight, portable, computerized
device that can identify an abnormal heart
rhythm that needs a shock.

Answer 3

Automated External Defibrillator (AED)

Question 4

can then deliver a shock that can
stop the abnormal rhythm and allow the
heart’s normal rhythm to return.

Answer 4

Automated External Defibrillator (AED)

Question 5

is a process in which an
electronic device (such as AED) gives an
electrical shock to the heart.

Answer 5

Defibrillation

Question 6

stops Ventricular Fibrillation
(VF) by using an electrical shock and
allows the return of a normal heart rhythm.

Answer 6

Defibrillation

Question 7

Indications and Importance Defibrillation (6)

Answer 7

Early defibrillation is critical for victims of sudden
cardiac arrest because:
• The most frequent rhythm in sudden
cardiac arrest is Ventricular Fibrillation
(VF).
• The most effective treatment for VF is
defibrillation.
• Also indicated for Pulseless Ventricular
Tachycardia.
• Defibrillation is most likely successful if it
occurs within minutes of collapse (sudden
cardiac arrest).
• Defibrillation may be ineffective if it is
delayed.
• VF deteriorates to asystole if not treated.

Question 8

Shockable Rhythms (2)

Answer 8

Ventricular Fibrillation
Pulseless Ventricular Tachycardia

Question 9

Shockable Rhythms
- An arrhythmia that occurs when the
ventricles beat with rapid and erratic
electrical impulses

Answer 9

Ventricular Fibrillation

Question 10

Shockable Rhythms
- Useless quivering of the heart with no
blood flow.

Answer 10

Ventricular Fibrillation

Question 11

Shockable Rhythms Ventricular Fibrillation
- _ is depleted of oxygen &
metabolic substrates.

Answer 11

Myocardium

Question 12

Shockable Rhythms
- Rhythm causing ‘all’ sudden cardiac arrest

Answer 12

Ventricular Fibrillation

Question 13

Shockable Rhythms
- is the treatment of
choice in Ventricular Fibrillation

Answer 13

Rapid Defibrillation

Question 14

Shockable Rhythms
- Very rapid but ineffective ventricular
contractions leading to insufficient organ
perfusion and heart failure.

Answer 14

Pulseless Ventricular Tachycardia

Question 15

Pulseless Ventricular Tachycardia Rate

Answer 15

greater than 180 beats per minute

Question 16

Pulseless Ventricular Tachycardia Rhythm

Answer 16

very wide QRS complex in ECG
tracings and originates in the ventricles. The patient will be pulseless

Question 17

Non-Shockable Rhythms (2)

Answer 17

Asystole
Pulseless Electrical Activity

Question 18

Non-Shockable Rhythms
- Absence of ventricular contractions

Answer 18

Asystole

Question 19

Non-Shockable Rhythms
- An organized, slow rhythm that does not
produce a pulse

Answer 19

Pulseless Electrical Activity

Question 20

Special Conditions That Affect the Use of AED (5)

Answer 20

• The victim is one month old or less.
• The victim has a hairy chest.
• The victim is lying in the water, immersed in
water, or water is covering the victim’s
chest.
• The victim has implanted defibrillator or
pacemaker.
• The victim has a transdermal medication
patch or other objects on the skin’s surface
where the AED electrode pads are placed.

an _, it is
reasonable that the defibrillator be used _

Answer 23

witnessed adult cardiac arrest
AED is immediately available
as
soon as possible.

Question 24

Shock First Vs. CPR First
- For _
or for whom _, it is reasonable that _ be
initiated while the defibrillator equipment is
being retrieved and applied and that
defibrillation, if indicated, be attempted as
soon as the device is ready for use.

Answer 24

adults with unmonitored cardiac arrest
an AED is not immediately
available
CPR
