cardiopulmonary resuscitation

Question 1

cardiac arrest

Answer 1

sudden cessation of effective circulation and ventilation
may come after respiratory arrest

Question 2

cardiopulmonary resuscitation

Answer 2

CPR, preserving life by restoring effective circulation and ventilation

Question 3

causes of cardiopulmonary arrest

Answer 3

respiratory impairment
ventilation problems
cardiac disorders
electrolyte imbalance
drug toxicity
severe shock or trauma

Question 4

process of cardiac arrest

Answer 4

hypoventilation
hypoxia
acidosis
respiratory arrest
cardiac arrest

Question 5

clinical signs of unresponsive patient

Answer 5

unconsious, no effective ventilation, no pulse or heart beat, no heart sounds, fixed pupils, grey mm

Question 6

CPR goals

Answer 6

prevent irreversible brain damage
respore ventilation and circulation

Question 7

chain of survival

Answer 7

early recognition
effective CPR
post resucitation care
success under GA-
47%-dog 42%-cat
success not under GA
<6%-dogs <20%-cats

Question 8

unresponsive patient

Answer 8

15-30 sec for initial assessment
snake, shout, watch for breath, circulation, check airway

Question 9

ALS step 3 - monitoring

Answer 9

ECG - diagnose rhythm and determine effective treatment
capnograph-
BP
pulse ox

Question 10

ALS step 4 - vascular access

Answer 10

IV preferred
intratracheal
intraosseous

Question 11

perfusing rhythm

Answer 11

consistant repeating complex
pulse

Question 12

ventricular fibrillation

Answer 12

shockable rhyrhm
no pulse, no consistant complex, ECG not flatlining

Question 13

pulseless ventricular tachycardia

Answer 13

shockable rhythm
no pulse
consistant repeating complexes
wide complex
rate >200bpm

Question 14

pulse electrical activity

Answer 14

non shockable rhythm
PEA
no pulse
irregular repeating complexes
rate<200bpm
can last up to 10 mins after CPA

Question 15

asystole

Answer 15

non shockable rhythm
no pulse
no repeating complex
flat tine

Question 16

vasopressors

Answer 16

drug therapy
peripheral vasoconstriction to redirect blood from the periphery to the vital organs, increasing venous pressure

Question 17

important tips

Answer 17

change compressor every 2min cycles
team leader to call instructions
record times, drugs, monitoring

Question 18

return of spontaneous circulation

Answer 18

ROSC
assess patient vitals, bloodwork

Question 19

post resuscitation care

Answer 19

35% of patients may survive resuscitation but only 5% survive discharge due to organ failure, brain damage
continuous monitoring, ECG, BP, blood gas analysis, temp, urine output
