Q

How do the cardiac and thoracic pump theories differ?

A

(What they are (cardiac pump is actually pumping the heart vs thoracic is changing the intrathoracic pressure to pump the heart) and what patients they are used on (15 kg or lighter should get cardiac pump, everything bigger gets thoracic))

Q

Why should you allow the chest to completely recoil prior to your next chest compression during CPR?

A

(To allow maximal venous return to the heart)

Q

Describe the following arrest rhythms and state whether they are a shockable rhythm or not:

  • Asystole
  • Pulseless electrical activity
  • Ventricular fibrillation
  • Pulseless ventricular tachycardia
A

Asystole (Your classic flat line, NOT shockable)
Pulseless electrical activity (ECG shows normal electrical waves just slower than the should be but the animal has no pulse, NOT shockable)
Ventricular fibrillation (Erratic waves that have no rhyme or reason, shockable)
Pulseless ventricular tachycardia (Looks like vtach would in a live animal but this animal has no pulse, tall peaks with no distinguishable q or t waves, shockable)

Q

What is the purpose of defibrillation in cases where it is appropriate?

A

(It’s in the name, defibrillation, you’re shocking (de) the heart so it stops freaking out (fibrillation) and it can return to normal electrical activity)

Q

What are the two more commonly used CPR drugs?

A

(Epinephrine and atropine (more useful for before arrest when patients are bradycardic), all other drugs should be considered on a case by case basis)

Q

(T/F) Lidocaine can reduce the likelihood of successful defibrillation.

A

(T, it suppresses ventricular activity including escape beats (which are kinda important for CPR))

Q

Fluid therapy is only appropriate for cases of CPA involving what type of patients?

A

(Hypovolemic patients, if done in patients who are not hypovolemic fluids can reduce coronary perfusion)
