victim is in a dangerous environment
High quality CPR includes starting chest compressions within how many seconds after
recognition of cardiac arrest in victims of all ages? - Answer-10 seconds
interruptions of chest compressions should be limited to how many seconds? - Answer-
10 seconds
how can you tell when a rescue breath for an infant victim is effective? - Answer-there is
visible rise of the chest
what is the best method of opening the airway of an unresponsive victim when you do
not suspect cervical spine injury? - Answer-use the head tilt chin lift

Answer-bag mask device
what is likely to cause air to enter the victims stomach( gastric inflation) during bag
mask ventilation? - Answer-breaths are given to quickly or with to much force
What are the correct compression and ventilation rates for 2 rescuers CPR in the
prescience of an advanced airway in adult victim? - Answer-compress at a rate of at
least 100 per min with 2 breaths every 5 to 10 secs
how does complete chest recoil contribute to effective CPR? - Answer-allows the heart
to refill with blood between compressions
what is the recommended compression- ventilation ratio for 2 rescuer adult CPR? -
Answer-30:2 for 2 rescuer
to reduce fatigue during CPR, how often should compressions switch roles? - Answer-
after every 5 cycles of compressions and breaths
what is the recommended compression rate for performing CPR on a victim of any age?
- Answer-100 per min
,during 2 rescuer CPR, one rescuer will provide chest compressions. what is the role of
the second rescuer? - Answer-maintain an open airway and give breaths
why are chest compression important? - Answer-they pump blood to the rest of the
body
what is the first step to perform once the AED arrives on the scene? - Answer-turn on
the AED
When should you deliver a shock from the AED? - Answer-after the AED activates a
shock, charge, states a "clear the victim", and prompts me to push the shock buttom
what is the best way to relieve severe chocking in a responsive adult? - Answer-perform
abdominal thrust
what is the correct depth of chest compression for a child victim? - Answer-at least one
third the depth of the chest, approx 2 inches
What is the recommended compression ventilation ration for 2 rescuer child CPR? -
Answer-15:2
what size AED pads should be used for child less that 8 years of age? - Answer-adult
pads/ dose may be used if peadrtic pads are not available
a choking adult become unresponsive while you are doing abdominal thrust for severe
chocking. what should you do next? - Answer-begin CPR
what is the recommended compression ventilation ration for 1 rescuer infant CPR -
Answer-30:2
what is the preferred technique for providing chest compressions during 2 rescuer CPR
for an infant? - Answer-the 2 thumb - encircling hands technique
where is the brachial pulse located? - Answer-on the inside of the upper arm between
the elbow and the shoulder.
As of 2017, what percent of people who have an out-of-hospital, non-traumatic cardiac
arrest, treated by EMS, survive to be discharged from the hospital? - Answer-10%
How does the AHA define adults, children and infants? - Answer-Adults = adolescents
(ie., after the onset of puberty and older
Children = 1 year of age to onset of puberty
Infants = less than 1 year of age (excluding newly born infants in the delivery room)
What are signs of puberty? - Answer-Chest or underarm hair in males and any breast
development in females.
, The BLS Course focuses on preparing students to perform ___ skills. - Answer-CPR
What are the two components of CPR? - Answer-1) chest compressions
2) breaths
What do these all describe?:
*Start compressions within 10 seconds
*Push hard, push fast
*Allow complete chest recoil
*Minimize interruptions
*Give effective breaths
*Avoid excessive ventilation - Answer-High-Quality CPR
How soon should compressions be started after the recognition of cardiac arrest? -
Answer-Within 10 seconds
At what rate should chest compressions be given? - Answer-100-120 beats/minute
At what depth should chest compressions be given in adults? - Answer-At least 2 inches
(5 centimeters)
At what depth should chest compressions be given in children? - Answer-At least 1/3
depth of chest , about 2 inches (5 centimeters)
At what depth should chest compressions be given in infants? - Answer-At least 1/3
depth of chest, about 1.5 inches (4 centimeters)
High-quality CPR includes minimizing interruptions in chest compressions. Try to limit
interruptions to less than __ seconds. - Answer-10
What constitutes an effective breath in high-quality CPR? - Answer-Making the chest
rise
Chest compressions are more often too shallow than too deep. However, research
suggest that compression depth greater than 2.4 inches (6 centimeters) in adults may
cause injuries. If you have a CPR quality feedback device, what is the optimal target for
compression depth? - Answer-2 - 2.4 inches (5 - 6 cm)
With adults, what is the first thing you should do when you recognize the adult is not
responsive? - Answer-Activate EMS or ask someone to do it.
The sooner you activate EMS, the sooner the next level of care can arrive. Start high-
quality CPR without delay.
___ bridges the transition from BLS to more advanced care. - Answer-ALS
