CPR/Recover Flashcards
____ is cessation of normal circulation due to failure of the heart to contract effecively?
Cardiopulmonary arrest (CPA)
___ is an emergency procedure performed in order to MANUALLY maintain perfusion until spontaneous circulation is resorted?
Cardiopulmonary resuscitation (CPR)
T/F if CPA does not have a reversible cause, CPR is unlikely to be successful so you should not attempt?
True
T/F CPR has a 25% success rate regardless of the inciting cuase of the CPA
False- 5%
if anesthetic-related it is 25%
What are 3 key features to recognize CPA?
1) loss of consciousness
2) loss of normal, spontaneous breathing
3) loss of palpable pulses
What are 4 common events that precede CPA?
1) bradycardia
2) worsening mentation
3) sudden increase in vagal tone (vomiting, straining to defecate)
4) sudden change in breathing pattern
What are a few common conditions that predispose a patient to CPA and therefore warrant intense monitoring and aggressive therapy?
sepsis
SIRS
heart failure
pulmonary disease
trauma
neoplasia
general anesthesia
T/F you should have 2 people at minimum for CPR
False- THREE
What are some roles that can be given to persons involved in CPR?
Leader (directs everyone, best for this person to be the one who knows the patient the best)
Ventilator
Compressor
Time keeper
Recorder
Drug administrator
What are some things to make handy on your crash cart?
ET tubes
Ambu bags
laryngoscope
gauze squares
ET tubes ties and cuff syringe
ECG and supplies
defibrillator
drugs – epi and atropine
drug chart
catheter supplies
suction supplies
end tidal CO2 monitor
At what point should you discuss CPA with an O?
BEFORE the patient has arrested/ Always discuss the likelihood of CPA occurring with the patients current condition or status and explain the success rates of CPA.
obtain their wishes.
What are the 3 components of BASIC life support?
1) circulation
2) airway
3) Breathing
T/F you should establish an airway prior to starting compressions?
False – opposite
start manual compressions immediately, then place ET tube and start providing manual breaths.
Once a patient is intubated and compressions are continuing, you should be giving manual breaths. What % oxygen should you put the patient on and how many breaths/min should you give the patient?
100% oxygen
8-12 breaths/min
if you give too many, this can decrease venous return to the heart
What is the difference between the thoracic pump theory and the cardiac pump theory in regard to manual chest compressions during CPR?
Thoracic pump for large breed dogs; we have to place our hands over the widest part of the chest in order to cause the greatest change in intrathoracic pressure to generate adequate blood flow.
Cardiac pump – for smaller animals; placing hands directly over heart space to push blood forward
How many compressions do you give a patient per minute during CPR and how hard should these compressions be?
100 per minute
you should do them to depress the chest by 1/3 and allow COMPLETE recoil of the chest (this is when the venous blood returns to the heart, which is required)
What are indications for open chest CPR?
large and giant breed dogs
thoracic trauma
pleural or pericardial space disease
intraoperative arrest
ineffective chest compressions
What are the 4 heart rhythms of CPA?
asystole
pulseless electrical activity
pulseless VTACH
ventricular fibrillation
What are the shockable rhythms?
Ventricular fibrillation
pulseless ventricular tachycardia
How can you obtain emergency venous access in patients during CPA?
Venous cut down
intraossesous catheter
What is the most common drug used in CPA?
Epinephrine
What drug can be used BEFORE arrest for bradycardia?
Atropine
T/F lidocaine is routinely used in CPA for correction of arrhythmias?
False its not routinely used
it suppresses ventricular activity and many reduces likelihood of successful defibrillaiton
When should you give fluid therapy during CPA?
Not in all cases
only if the patient was hypovolemic
can reduce coronary perfusion
