m m m m m m m m m m m m m m
survive to hospital discharge? - ANSWER: ➡ 10%
m m m m m m mm m
For the purposes of the BLS course, age definitions are as follows: - ANSWER: ➡ Adult: after
m m m m m m m m m m m m m mm m m
onset of puberty and older
m m m m m
Children: 1 year to puberty m m m m
Infant: <1 year of age m m m m
What are the components of CPR? - ANSWER: ➡ Airway check, chest compressions, and
m m m m m m m mm m m m m m
breaths
m
What are the steps for high quality CPR? - ANSWER: ➡ 1. Start compressions wishing 10
m m m m m m m m m mm m m m m m
seconds of recognition of cardiac arrest
m m m m m m
2. Push hard and fast (rate of 100-120/min)
m m m m m m m
3. Allow complete chest recoil after each compression
m m m m m m m
4. Minimize interruptions in compressions (less than 10 seconds)
m m m m m m m m
5. Give effective breaths that make the chest rise
m m m m m m m m
6. Avoid excessive ventilation

How deep should you compress for each age group? - ANSWER: ➡ Adults: at least 2 inches
m m m m m m m m m m mm m m m m m
Children: at least 1/3 of the depth of the chest; about 2 inches
m m m m m m m m m m m m
Infants: at least 1/3 of the depth of the chest; about 1.5 inches

, What is a cath lab? - ANSWER: ➡ A cardiac catheterization lab is a group of procedure rooms
m m m m m m mm m m m m m m m m m m
in a hospital/clinic where specialized equipment is used to evaluate the heart and the blood
m m m m m m m m m m m m m m m
vessels around the heart and in the lungs
m m m m m m m m
What does a cardiac catheterization procedure entail? - ANSWER: ➡ It involves the insertion
m m m m m m m m mm m m m m
of a catheter through an artery or vein into the heart to study the heart and its surrounding
m m m m m m m m m m m m m m m m m m
structures and function. Measurements and contrast material can help diagnose problems
m m m m m m m m m m m
or the catheter can be used to fix some problem (like a blocked artery)
m m m m m m m m m m m m m m
How would you recognize that someone has had cardiac arrest? - ANSWER: ➡ The victim
m m m m m m m m m m m mm m m
will be unresponsive, not breathing or only gasping, and no pulse
m m m m m m m m m m m
How does rapid defibrillation work and what effect does it have on a patient undergoing
m m m m m m m m m m m m m m
cardiac arrest? - ANSWER: ➡ Rapid defibrillation can identify lethal heart rhythms and
m m m m mm m m m m m m m m
deliver a shock to terminate the abnormal rhythm and allow the heart's normal rhythm to
m m m m m m m m m m m m m m m
resume. In conjunction with high-quality CPR, rapid defibrillation can double or triple the
m m m m m m m m m m m m m
chances of survival

In adults, cardiac arrest is often sudden and results from a cardiac cause. How does cardiac
m m m m m m m m m m m m m m m
arrest usually present in children? - ANSWER: ➡ In children, cardiac arrest is often
m m m m m m m mm m m m m m m
secondary to respiratory failure and shock. Identifying children with these problems is
m m m m m m m m m m m m
essential to reduce the likelihood of pediatric cardiac arrest and maximize survival and
m m m m m m m m m m m m m
recovery. Therefore, a prevention link is added in the pediatric Chain of Survival.

What is the difference between cardiac arrest and a heart attack? - ANSWER: ➡ Sudden
m m m m m m m m m m m m mm m
cardiac arrest occurs when the heart develops an abnormal rhythm and can't pump blood. A
m m m m m m m m m m m m m m m
heart attack occurs when blood flow to part of the heart muscle is blocked
m m m m m m m m m m m m m m
When does cardiac arrest occur (what happens with the cardiology)? - ANSWER: ➡ Sudden
m m m m m m m m m m m mm m
cardiac arrest results from an abnormal heart rhythm. This abnormal rhythm causes the
m m m m m m m m m m m m m
heart to quiver so it can no longer pump blood to the brain, lungs, and other organs. Sudden
m m m m m m m m m m m m m m m m m m
cardiac arrest is often a "rhythm" problem.
