ACLS BASICS AND STEMI
1. what is a step in the closed-loop communication?
Answer: confirming task completion before assigning another task
2. Coronary Perfusion Pressure (CPP)=
Answer:
Aortic *Diastolic* Pressure MINUS
*Right* Atrial *diastolic* Pressure
3. a CPP of or greater must be achieved during CPR.
Answer: 15mmHg
4. In a patient with an arterial line, a reasonable surrogate for CPP is:
Answer: arterialrelaxation or diastolic pressure
5. ETCO2 is used to
Answer: estimate tissue perfusion and quality of chest compressions
6. How do interruptions in chest compressions negatively impact survivalafter cardiac
arrest?
Answer: Decrease Coronary Perfusion Pressure (CPP)
7. what are the components of high-quality CPR?
Answer:
-Switching compressors q 2minutes
-avoiding excessive ventilation
-compression depth of 2 inches (5cm)
-Complete chest recoil after each compression
-interruptions <10seconds
8. Which high-performance team member is part of the resuscitation triangle?
Answer: monitor/defibrillator/CPR coach
9. What is one of the most important determinants of survival from cardiacarrest?
Answer: The interval from collapse to defibrillation
10. What is a common initial rhythm in out-of-hospital witnessed suddencardiac arrest?
Answer: Ventricular Fibrillation (VF)
11. Ventricular Fibrillation definition:
Answer: When the heart quivers and does not pumpblood
12. what is the most effective way to treat Ventricular Fibrillation?
, Answer: CPR then
*Electrical Defibrillation*
13. Pulseless Ventricular Tachycardia deteriorates to?
Answer: Ventricular Fibrillation
14. Ventricular Fibrillation deteriorates to?
Answer: Asystole
15. For every minute that passes between collapse and defibrillation, the chance of survival
from a witnessedVF sudden cardiac arrest declines by whatpercent WITH CPR?
Answer: 3-4% per minute
16. Early CPR can the survival rate from a witnessed sudden cardiacarrest?
Answer: double or triple
17. Which compressor should resume compressions after a defibrillatorshock?
Answer: the same compressor
18. When pressing the shock button, the defibrillator operator should facewhat?
Answer: the patient NOT the machine
19. What is the only intervention that can restore an organized rhythm inpatients with
ventricular fibrillation?
Answer: early and effective defibrillation
20. The systematic approach consists of:
Answer:
-Initial impression (visualization/scenesafety)
-BLS assessment
-Primary assessment (ABCs, Disability, Exposure)
-Secondary Assessment (SAMPLE/focused Hx, H'S, T'S)
21. In addition to decreased IHCA, what are some of the other benefits of implementing a
rapid response system?
Answer:
-decreased in total hospital length ofstay
-decreased ICU length of stay
22. what is the advantage of a systematic approach to patient assessment?
Answer: -Reduces the chances of missing important signs and symptoms
23. How quickly does the chance of survival decline for every minute ofdefibrillation delay in
patients with VF who do not receive CPR?
Answer: 7-10%
