Flashcards in 1. Advanced Life Support Deck (20):
1

What are the 2 shockable rhythms?

VT and VF

2

What are the 2 non-shockable rhythms?

Non-shockable asystole and PEA/EMD (pulseless electrical activity)

3

What are the 4 Ts?

1. Tamponade: pericardial
2. Tension pneumothorax
3. Toxins, poisons, drugs
4. Thrombosis: pulmonary or coronary

4

What are the 4 Hs?

1. Hypoxaemia
2. Hypovolaemia
3. Hypo or hyperthermia
4. Hypo or hyperkalaemia

5

Action: adrenaline

Causes peripheral vasoconstriction and thought to facilitate defibrillation by improving blood flow

6

Action: amioderone

Blockage of potassium channels and increased conduction , prolonged refractory period

7

Action: atropine

Parasympathetic antagonist: blocks action of vagus nerve

8

Action: sodium bicarbonate

Systemic alkalising agent: increases plasma bicarb and buffers excess H+

9

Indications: adrenaline

Immediately - non shockable rhythm VF
VF/VT - after 2nd shock

10

Indications: amioderone

VF/pulseless VT when defib and adrenaline has failed. Increases vasodilation and decreased HR and contractilitiy

11

Indications: Atropine

No longer recommended systole or cardiac arrest

12

Indications: Sodium bicarbonate

Severe metabolic acidosis, hyperkalaemia

13

Adverse effects: adrenaline

Tachycardia, dyspnoea

14

Adverse effects: amioderone

Hypotension, bradycardia, heart block

15

Adverse effects: atropine

Tachycardia, palpitations

16

Adverse effects: sodium bicarbonate

Alkalosis, hypernatraemia

17

Dose: adrenaline

1mg IVI (1;1000)

18

Dose: amioderone

300mg after 3rd shock

19

Dose: atropine

500 - 600mcg every 3-5 min (up to 3mg)

20

Dose: sodium bicarbonate

IV 1mmol/kg over 2/3 min
