High Performance CPR

Question 1

ATP (Adenosine Triphosphate)

Answer 1

Fuel that drives every energy process in the body.

Unsupported VT - ATP concentration in the heart declines.
>40mins, shocking will likely result in asystole or PEA.
Not enough ATP to drive the heart.

Question 2

Compressions

Answer 2

• INCREASE intrathoracic pressure
• EJECTS blood from the heart and lungs
• Increases forward output and BP

PERFUSES THE BRAIN

Rate: 100-120cpm
Depth: 2inches (50mm)

Question 3

Decompressions

Answer 3

RECOIL

• DECREASED intrathoracic pressure
• REFILLING of the heart and lungs
• Increases vacuum, increased refilling, increased forward output

PERFUSES THE HEART

Allow for full chest recoil

Question 4

Aortic and venous pressures

Answer 4

Aortic
- does not fall to zero during cpr due to closure of the aortic valve.

Venous
- does not change outside of the chest so that organ perfusion is maintained. W

• The pressure inside the L & R ventricles are equal during cpr

Question 5

4 metrics of high performance cpr

Answer 5

• RATE: 100-120cpm
• DEPTH: 2inches (50mm)
• Full chest recoil
• MinImise interruptions: >80%

Question 6

EXCITE

Answer 6

E - empowerment

X - expect survival

C - cpr

I - excellence in care

T - team work

E - environment

Question 7

Chain and frame of survival

Answer 7

CHAIN
- Call for help
- Early CPR
- Early defibrillation
- Early advanced care

FRAME

- Culture of excellence

Question 8

COACHED

Answer 8

Used during the defibrillation cycle

C Continue compressions
O Oxygen away
A All others away
