Flashcards in Cardiac Arrest Deck (14):
1

What are the four types of cardiac arrest?

Ventricular fibrillation, ventricular tachycardia, asystole and pulseless electrical activity

2

What are the characteristics of VF

Irregular chaotic baseline with very broad QRS waveforms, patients are pulseless. (ECG looks like a messy line)

3

VT characteristics are?

Regular, broad QRS, may have a pulse

4

Asystole characteristics are?

Baseline with low grade fluctuation (if at all), no pulse

5

PEA characteristics are?

A sinus rhythm that would be expected to produce sufficient CO but there is no pulse

6

What clinical features diagnose cardiac arrest?

Loss of consciousness, no pulse in the carotid, no/minimal respiratory effort

7

What is the first step of management?

ABC assesment and BLS

8

Who should you call?

The resus team

9

Which rhythms are shockable?

VF and pulseless VT

10

What rhythms aren't shockable?

Asystole, VT with pulse, PEA

11

What drug is given to all patients and how often is it given?

Adrenaline every 3-5mins

12

What other drugs might you give?

Atropine (inhibits parasymp) and amiodarone (esp for ventricular arrythmias)

13

If patient stabilises what should you do next?

Send to HDU, do a full examination, FBC, U+E, ABG, CEs, lipids, glucose and an ECG

14

Definition of cardiac arrest is?

Sudden loss of cardiac output with loss of consciousness
