BLS Resuscitation

Question 1

What are the 3 reasons for respiratory failure?

Answer 1

Constrict, obstruct, destroy

Question 2

If left untreated, what does respiratory arrest always lead to?

Answer 2

Cardiac Arrest

Question 3

Every minute of cardiac arrest that passes without CPR, chance of survival decreases by how much?

Answer 3

10%

Question 4

Brain damage begins how long after cardiac arrest?

Answer 4

4-6 minutes

Question 5

Brain damage becomes irreversible after how long of cardiac arrest?

Answer 5

8-10 minutes

Question 6

What is an EKG?

Answer 6

Electrocardiogram

Question 7

What is the P wave on an EKG

Answer 7

Atrial Depolarisation

Question 8

What is the R wave on an EKG

Answer 8

Ventricular depolarisation

Question 9

What is the T wave on an EKG

Answer 9

Ventricular repolarisation

Question 10

What is a normal sinus rhythm?

Answer 10

cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. A normal heart rhythm

Question 11

What is asystole?

Answer 11

There is no heart function present. Flat line

Question 12

What does an AED say when asystole is detected?

Answer 12

No shock advised

Question 13

What is V fib

Answer 13

Ventricular fibrillation

The heart more just vibrates due to rapid and irregular beating patterns

Question 14

What does an AED say when V Fib is detected?

Answer 14

Shock advised

Question 15

What is V tach?

Answer 15

Pulseless ventricular tachycardia

A rapid pulse starts in a ventricle instead of the SA node. It can be regular

Question 16

What does the AED say when V tach is detected?

Answer 16

Shock advised

Question 17

What is treatment for V fib and V tach?

Answer 17

CPR and defibrillation

Question 18

Can you detect a pulse during v fib and v tach?

Answer 18

No

Question 19

How many cycles of CPR between each AED shock?

Answer 19

5

Question 20

H’s and T’s of reversible causes of cardiac arrest

Answer 20

Hypoxia
Hypothermia

Toxins (specifically opiates)

Question 21

What is supine hypotension syndrome and how do you fix it?

Answer 21

A pregnant woman’s baby rests on her vena cava cutting off return blood flow to the heart. Shove the baby to the side and begin CPR

Question 22

What are the two cases when you do not perform CPR?

Answer 22

Obvious/irreversible death

DNR orders

Question 23

What is ROSC?

Answer 23

Return of spontaneous circulation

Question 24

What are the steps of post-resuscitative care?

Answer 24

1. Obtain baseline vitals and apply continuous monitoring
2. Prepare for transport and re-arrest
3. Place continuous CPR device if available and not already set up
4. High-priority transport to the closest appropriate hospital
