asystole

5
New cards

Which types of cardiac arrest rhythms are not shockable?

  • asystole

  • PEA

6
New cards

Which types of cardiac arrest rhythms are shockable?

  • ventricular fibrillation

  • pulseless ventricular tachycardia

7
New cards

What interventions can we do for non-shockable rhythms?

  • CPR

  • address underlying causes

  • medications

8
New cards

What is ventricular fibrillation (v-fib)?

chaotic, irregular, disorganized electrical activity with no recognizable QRS complexes

9
New cards

What is pulseless ventricular tachycardia (pVT/v-tach)?

rapid, regular, wide-complex rhythm (>100-150 bpm) that does not produce a pulse

10
New cards

What is asystole?

total absence of ventricular electrical activity (flatline)

11
New cards

What is pulseless electrical activity (PEA)?

organized ECG rhythm (such as sinus bradycardia or tachycardia) present but patient has no palpable pulse

12
New cards

What is antero-lateral (AL) defibrillation pad placement?

  • lateral pad (usually has a ❤︎⁠ on it) centered along 5th intercostal space mid-axillary line

  • anterior pad placed mid-clavicular line just below clavicle

13
New cards

What is antero-posterior (AP) defibrillation pad placement?

  • lateral pad (usually has a ❤︎ on it⁠) placed anterior → centered over apex area

  • posterior placed same horizontal level between spine + shoulder blade

New cards

What is the helpful saying to remember the 4-lead ECG limb lead placement?

smoke over fire (black over red) = LA over LL

snow over grass (white over green) = RA over RL

15
New cards

Where should the 4-lead ECG limb leads be placed on the patient?

RA (white/snow) = right arm

RL (green/grass) = right leg

LA (black/smoke) = left arm

LL (red/fire) = left leg

<p>RA (white<span><span>/</span></span>snow) = right arm</p><p>RL (green<span><span>/</span></span>grass) = right leg</p><p>LA (black<span><span>/</span></span>smoke) = left arm</p><p>LL (red<span><span>/</span></span>fire) = left leg</p>
16
New cards

What should be considered if patient is shaking/moving excessively?

torso placement of pads → reduces motion artifact

17
New cards

What should be considered if patient has dry or excessively flaky skin?

rub skin with 2×2 gauze to optimize adherence
