Q

Which rhythms are considered “shockable”?

A

VF
pulseless VT - ventricular contraction is so rapid that there is no time for the heart to refill, resulting in undetectable pulse

Q

Which rhythms are NOT considered “shockable”?

A

Asystole
pulseless-electrical activity - heart stops because the electrical activity in your heart is too weak to make your heart beat (ECG shows trace, but no pulse)

Q

Key points for defibrillation

A

a single shock for VF/pulseless VT followed by 2 minutes of CPR
If already on CCU –> straight to 3 consecutive shocks

Q

Key points re adrenaline
1. Non-shockable rhythms
2. Shockable rhythms
3. When to repeat

A
  1. adrenaline 1 mg as soon as possible for non-shockable rhythms (1mL of 1:1,000 or 10mL of 1:10,000)
  2. during a VF/VT cardiac arrest, adrenaline 1 mg is given once chest compressions have restarted after the third shock
  3. repeat adrenaline 1mg every 3-5 minutes whilst ALS continues

Q

Key points re amiodarone
1. What patient group should be given it
2. Alternative

A
  1. amiodarone 300 mg should be given to patients who are in VF/pulseless VT after 3 shocks have been administered.
    - a further dose of amiodarone 150 mg should be given to patients who are in VF/pulseless VT after 5 shocks have been administered
  2. Lidocaine

Q

Key points re thrombolytic drugs

Consider if PE suspected
If given, CPR should be continued for an extended period of 60-90 minutes
