Cardiopulmonary Resuscitation

Question 1

Circulation CPR discuss

Answer 1

• Rate 100 - 120 per min
• 5-6cm deep
• Aim : target end-tidal CO2 >10mmHg
  Diastolic BP > 20mmHg

Question 2

Breathing

Answer 2

• Adult ratio  30:2
• Children / infants  30:2 (2 rescue breaths and then 15:2)

Question 3

Defib

Answer 3

• Shockable rhythms = ventricular tachycardia and ventricular fibrillation!
• Any other rhythm is non-shockable
• TBH uses biphasic defibrillators  150 J

Question 4

Shockable rhythms (defibrillation):

Answer 4

• Ventricular fibrillation
• Pulseless ventricular tachycardia

Question 5

Drugs for resus

Answer 5

consider adrenaline (incr SVR) and antiarrhythmics

**- Adrenaline = start 1 mg every 3 – 5 mins = incr SVR & CO

**- Amiodarone or lignocaine
o Usually use when there is a resistant shockable wave  resistant VT or VF
o Amiodarone (preferred)  300 mg followed by 150 mg

Amiodarone can be used in VT & SVT, unlike adenosine which can only be used in SVT!

Question 6

POSSIBLE cause of arrest

Answer 6

• Hypoxia
• Hypovolaemia
• Hypothermia
• Hydrogen ion = acidosis
• Hypo- / hyperkalaemia
• Hypoglycaemia
• Tension pneumothorax
• Tamponade (cardiac)
• Toxins
• Trauma
• Thrombosis (coronary)
• Thrombosis (pulmonary)
