At 21:07 you receive a call from the husband of a 67-year-old woman
who has collapsed and is currently unconscious and described as
breathing "funny." It is now 21:09; at this point, you have enough
information to identify that the patient is in cardiac arrest and start a
response. From the start of the call until the recognition of cardiac
arrest took 120 seconds.
Did you meet the AHA T-CPR performance recommendation for
recognition of out-of-hospital cardiac arrest? - ANSWER-No
You begin to coach the caller to position the patient flat on her back
on the floor, and you then provide instructions on how to perform
CPR. At 21:11, the caller begins counting out loud and you can
confirm that CPR compressions are being delivered. From the start of
the call until the first compression was delivered took 240 seconds.
Did you meet the AHA T-CPR performance recommendation for
delivery of the first T-CPR-directed chest compression? - ANSWER-
No
From the moment of collapse, a patient's chance of survival
decreases by as much as
??%
,As soon as CPR begins, the dying process is stalled, and the patient's
chance of surviving the arrest increases. - ANSWER-10%
Your caller has reported that her neighbor was found down,
unconscious, and unresponsive in his driveway. When you ask if he
is breathing (or "breathing normally," depending on your protocol)
the caller states "I'm not sure, I don't think so."
What course of action should you take? - ANSWER-Move directly into
CPR instructions.
A security guard at the mall has come across an adult man who is
down in the bathroom. The man's eyes are open, but he is
unresponsive. You ask if the man is breathing (or "breathing
normally," depending on your protocol), and the security guard
informs you, "If I didn't know better, I would say he's not breathing at
all. His eyes are open though; otherwise I would think he's dead."
What course of action should you take? - ANSWER-Proceed with
compression-only CPR instructions.
Poor-quality CPR is a preventable harm and is detrimental to patient
survival.
What are the 5 elements of high-quality CPR? - ANSWER--Minimizing
interruptions
-Compression depth
-Recoil
-Providing ventilation instructions when appropriate
, -Compression rate
You've coached the security guard to get the patient to the floor, and
you've instructed him on where to kneel and on correct hand
placement for performing CPR. It's now time to start compressions.
What compression rate must the rescuer maintain when performing
CPR? - ANSWER-100 to 120 compressions per minute
The rescuer is getting tired and having difficulty maintaining a correct
compression rate.
What can you do to help the rescuer maintain the correct rate? -
ANSWER-Correct and re-establish the rate, counting out loud so that
the rescuer can replicate your pace.
The Resuscitation Outcomes Consortium (ROC) study has shown that
if the CPR compression rate is either slower than 100 compressions
per minute or faster than 120 compressions per minute, a patient's
chance of survival is decreased - ANSWER-True
What happens when the rescuer delivers chest compressions that are
too shallow and that are delivered at a depth of 1.5 inches instead of
the recommended 2 inches? - ANSWER-Survival of the patient is
decreased by as much as 50%.
During CPR, if the chest is not allowed to fully recoil, the following
will occurs: - ANSWER--The quality of CPR is decreased. -The
return of oxygenated blood to the heart is decreased.
