The brachial artery located on the upper arm is used
in infants below 1 year old.
Rapid defibrillation
increases the chance of effectively restoring a normal heart rhythm.
Early CPR
provides vital oxygen to the brain and vital organs increasing the likelihood of recovery.
Post cardiac arrest care
reduces the possibility of long-term impairment and increases the chance of a victim making a full recovery.
