1

what is cardiopulmonary arrest (CPA)

sudden cessation of spontaneous and effective ventilation and circulation lack of systemic perfusion

2

what are some examples of CPA

hypovolemia, metabolic derrangemnt, electrolyte abnormalities, cardiac dx, brain injury, drug overdose, pulmonary dx, anemia

3

what is the goal of cardiopulmonary resuscitation

the return of spontaneous circulation

4

what things may you need in a resuscitation area

crash cart, venous access, airway management, drug therapy, doppler, oxygen, EKG, defibrillator

5

what drugs may in used for drug therapy with this

Epinephrine, atropine, diazepam, lidocaine, reversal agent

6

if airway is obscured what do we do

use a suction device

7

how can we verify airway intubation

proper chest movement, direct visualization, palpation, ETCO2

8

what patients cannot be intubated orotracheally

foreign bodies, pharyngeal swelling/mass, trauma, dental fixation

9

what we do use to ventilate a patient with

100% oxygen

10

what is the goal of cardiac compression

to pump blood to the lungs for as exchange -> systemic arterial blood flow, or to maximize blood flow to the coronary and cerebral vascular beds

11

what are the 2 theories of chest compression

thoracic pump, and cardiac pump

12

when do we use the thoracic pump

larger patients - over 10 kg

13

when do we use the cardiac pump

smaller patients, keel-chested dogs, flat chested dogs

14

what is the thoracic pump theory for circulation

overall increase in intrathoracic pressure
-promotes blood flow from the aorta into the systemic circulation
-blood is suctioned into the vena cava during recoil phase

15

what is the thoracic pump theory for chest compression

the heart acts a channel (blood flows passively through the heart)
-use the widest portion of the thorax

16

what is the cardiac pump theory for chest compression

direct compression of the heart, lateral recumbency, directly over the heart

17

what is interposed abdominal compression (3rd way/ 2ppl)

abdomen is compressed during relaxation phase of chest compression, increased effectiveness venous return and forward flow

18

when do we not use interposed abdominal compressison

known abdominal trauma, hemoperitoneum, recent abd sx

19

what are the current recommendations for chest compressions

lateral recumbency, 100-120 bpm, 1/3 to 1/2 chest diameter, 2 min cycle

20

what is internal compression direct internal cardiac compression

greater CO + BP, better perfusion, direct assess to ventricles, aortic inclusion

21

when might we do a direct interal cardiac compresion

very large dog, rib fractures, severe plerual effusion, pneumothorax, cardiac tamponade, when ROSC is not achieved in approx 5 min.

22

what should we do for BLS

ABC assessment (don't do if patient is apneic) -> CPR
Chest compression, intubate and ventilate full 2 min cycle without interruptions. Connect EKG and Capnograph

23

what fluids do we use

crystal/colloid fluid therapy

24

what is a intracardiac injection not recommended

risk of lacerating lung tissues, coronary vasculature, arrhymias

25

what should we know about atropine

vagolytic, vagal arrests, V/D, urinating/ defecating, laryngeal manipulation

26

what should we know about epinephine

vasoconstriction
ino/chronotropic
low dose every other compression cycle
high dose with prolonged CPR >10 min
may become ineffective in an acidic environment

27

what should we know about Lidocaine and Amiodarone

antiarrhythmic, (Amiodarone - do not use to IT admin), indicated for prolonged CPR, reversal agents

28

what is electrical defibrillation

application of an electrical shock to terminate a cardiac arrhythmia, global depolarization of myocadium

29

what is monophasic defibrillation

current is delievered in one direction between paddles

30

what is biphasic defibrillation

positive currect followed by a negative currect, lower energy setting -> more efficient and les myocardial damage
