What is considered the age of a child? - ✔✔1 year of age to puberty
What is considered the age of an infant? - ✔✔Less than 1 year of age (excluding newly born babies in the
delivery room)
What is high quality CPR? - ✔✔Start compressions within 10 seconds of recognition of cardiac arrest.
Push hard, push fast: Compress at a rate of 100 to 120 min with depth of 2 inches for adults, 1/3 depth
and about 2 inches for children, 1/3 depth of chest and 1 1/2 inches for infants
Allow complete chest recoil and minimize interruptions the less than 10 seconds
Early CPR with an emphasis on chest compressions - ✔✔If the victim is in cardiac arrest, begin high-
quality CPR without delay. Started immediately after cardiac arrest can greatly improve a victim's chance
of survival. Bystanders who are not trained in CPR are encouraged to at least provide chest compressions
and be guided by dispatcher's over the phone
Rapid defibrillation - ✔✔Rapid defibrillation in combination with high quality CPR can double or triple
the chances of survival. Provide defib and with a manual defib or AED as soon as the device is available.
AED - ✔✔Lightweight, portable device that can identify heart rhythms and deliver a shock to terminate
the abnormal rhythm and allow the heart's normal rhythm to resume. AED's are simple to operate,
allowing lay rescuers and healthcare providers to attempt defib safely
Multidisciplinary post cardiac arrest care - ✔✔Once ROSC is achieved the next link is for the patient to
receive post cardiac care. The advanced level of care is provided by a team of healthcare providers, they
aim to prevent cardiac arrest and improve long term survival.
ROSC - ✔✔Return of spontaneous circulation
, Immediate recognition of cardiac arrest and activation of the emergency response system -
✔✔Recognize that the victim is in cardiac arrest based on unresponsiveness, no breathing and no pulse.
Activate the emergency response unit right away.
Early CPR with an emphasis on chest compressions - ✔✔Begin high quality CPR without delay. This can
improve the chance of survival.
In which locations do most out of hospital cardiac arrests occur? - ✔✔Homes
Which is the most common cause of cardiac arrest in children? - ✔✔Respiratory failure or shock
What is the third link in the adult out of hospital chain of survival? - ✔✔Rapid defibrillation
Which statement best describes sudden cardiac arrest? - ✔✔When abnormal rhythm develops and the
heart stops beating unexpectedly
If the victim is breathing normally and a pulse is present - ✔✔Monitor the victim
If the victim is not breathing normally but a pulse is present - ✔✔Provide rescue breathing. Confirm that
the emergency response system has been activated. Continue rescue breathing, and check pulse about
every 2 minutes. CPR is there is no pulse. If opioid use is suspected use naloxone
If the victim is not breathing normally or is only grasping and has no pulse - ✔✔Begin high quality CPR
Importance of chest compressions - ✔✔When chest compressions are stopped, the blood flow to the
heart and brain decreases. It takes many compressions to increase blood flow to the heart and brain.
High quality chest compressions - ✔✔Single rescuers should use the compressions to ventilation ratio 30
compressions to 2 breaths
Compress at a rate of 100-120/ min
