Question 1

Answer 1

Adrenaline 1:10000
Amiodarone

Question 2

Dose and intervals we give Adrenaline 1:10000 at?

Answer 2

Shockable cardiac arrest
give on the 3rd shock and then alternate shocks (5th, 7th, 9th etc)
1 milligram

Non-shockable cardiac arrest
- administer as soon as access has been gained.
- administer this in alternate loops

• Adrenaline is a sympathomimetic that stimulates both alpha- and beta-adrenergic receptors.
• The results in myocardial and cerebral blood flor being enhanced during CPR, this helps CPR be more effective due to the increase in peripheral resistance which leads to an improved perfusion pressure.
