Cardiac Arrest

Question 1

What do you do if VF / VT identified

Answer 1

Defib + CPR up to 3x
IV adrenaline + amiadarone after 3 shocks and eery time 
- 10ml 1:10000 IV 
IV amiadarone 
- After 3 shocks
- 300mg I V

Question 2

What do you do if witnessed in CCU

Answer 2

3 shocks with defibrillator then CPR initiated

Question 3

If astyole

Answer 3

IV adrenaline ASAP
2 mins CPR
Recheck rhythm
Not able to defib

Question 4

What ae shockable rhythm

Answer 4

VT and VF

Question 5

Non shockable

Answer 5

Astyole

Pulseless electrical activity

Question 6

What suggests unstable patient that is peri-arrest

Answer 6

Shock - low BP <90
Sweat / pallor
Decreased consciousness
Confusion
Syncope
MI
HF

Question 7

How do you treat

Answer 7

ABCDE
IV access + bloods
ECG
Decide if stable or not

Question 8

If unstable

Answer 8

DC shock

Treat as per rhythm detected on defib

Question 9

If broad complex and regular

Answer 9

Assume VT

IV amiadarone infusion

Question 10

If broad complex and irregular

Answer 10

AF with BBB = treat as SVT

Polymorphic VT = magnesium sulphate

Question 11

If narrow and regular

Answer 11

Valsalva/. carotid sinus massage
IV adenosine if fails
Consider atrial flutter if fails

Question 12

If narrow and irregular

Answer 12

AF
Anti-coagulate
DC cardioversion or chemical if rhythm
BB for rate control

Question 13

What does of adrenaline in cardiac arrest

Answer 13

10ml of 1:10000

Question 14

What dose in anaphylaxis

Answer 14

0.5ml IM 1 in 1000

Question 15

If go into cardiac arrest what do you do

Answer 15

Start chest compression
Get defibrillator on ASAP which will see if shockable rhythm
Someone will call 2222 and get resus trolley
Wide bore IV access

Question 16

What is more likely to cause a shockable VT / VF

Answer 16

Metabolic disturbance

Question 17

What are most arrest

Answer 17

Non-shockable

Question 18

What are reversible causes of cardiac arrest

Answer 18

Hypovolaemia
Hypoxia
Hypo or hyperkalaemia
Hypothermia

Thrombus
Tamponade
Toxins
Tension pneumothorax

Question 19

What do you do if unstable tachycardia

Answer 19

Treat as VT
DC cardioversion
Consider IV amiadarone 300mg after over 10-20 mins
24 hour IV amiadarone infusion 900mg

Question 20

What do you do if stable

Answer 20

ECG to see if broad or narrow

Question 21

What causes narrow and Rx

Answer 21

AF if irregular = rate control
SVT if regular = vagal or adenosine if fails
Flutter if no response to SVT Rx = rate control + expert help

Question 22

What causes broad

Answer 22

VT
VF - usually in cardiac arrest
SVT + BBB
If irregular = expert help - AF with BBB

Question 23

How do you Rx AF

Answer 23

BB + CCB = 1st line rate control

Question 24

How do you treat flutter

Answer 24

BB

CCB CI

Question 25

How do you Rx SVT

Answer 25

Valsalva / carotid sinus

Adenosine if fails

Question 26

How do you Rx VT

Answer 26

DC cardioversion if unstable

IV amiadarone 300mg then 900 over 24 hour

Question 27

How do you Rx SVT with BBB

Answer 27

Same as SVT
