CPR and defibrillation

18
Q

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

A

No

19
Q

How many cycles of CPR between each AED shock?

A

5

20
Q

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

A

Hypoxia
Hypothermia

Toxins (specifically opiates)

21
Q

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

A

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

22
Q

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

A

Obvious/irreversible death

DNR orders

23
Q

What is ROSC?

A

Return of spontaneous circulation

24
Q

What are the steps of post-resuscitative care?

A
  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
