1
Q

Describe cardiopulmonary arrest and give 3 effects

A

Characterised by acute failure of the respiratory and circulatory system

  • Lack of O2 delivery to tissues
  • Cellular death
  • Cerebral Hypoxia
2
Q

Describe three causes of CPA

A

Anaesthetic complications
Hypovolaemia
Severe trauma

3
Q

Give three signs of CPA

A

Apnoea
No Palpable pulse
Bleeding stops at surgical site

4
Q

Describe three preparations that can be made to deal with CPA

A
  • CPR protocol
  • Training of staff
  • Crash cart/box
5
Q

What would you start with if you were alone dealing with a case of Cardio Pulmonary Arrest

A

Compressions
Airway
Breathing

6
Q

Describe the airway support that may be given in CPR

A

If aponea identified give 2-5 rescue breaths

  • Can use ET (orotracheal intubation) tube or ambu bage
  • May attempt emergency tracheostomy
7
Q

Describe the breathing support that may be given in CPR

A

PPV
10 breaths per minute
Stop ventilation if spontaneous breathing returns

8
Q

Describe the Circulation support for CPR

A

Cardiac Pump - Cats and narrow chested dogs blood forced through the large vessels (ventral 1/3 of the thorax 100-120 compressions per min)
Thoracic pump - Using both ventricles of the heart to generate output vol (widest part of the thorax 60-120comp/min

9
Q

Describe two drugs that can be used to help treat an animal in CPA

A
  • Admin determined by ECG
    Adrenaline - Increased myocardial contractability, increased heart rate, venocontraction (use when in ASTYSTOLE, ATROPINE RESISTANT BRADYC AND POOR DIASTOLIC FILLING)
    Atropine- Important in small animal CPR (increased incidence of VAGALLY MEDIATED BRADYCARDIA)
    Increases heart rate, controls hypotension and increases systolic vascular resistance) Use in cases of VAGAL INDICATED ASYSTOLE.
10
Q

Describe three ways in which CPR drugs can be administered

A

IV - Cranial VC (can be difficult due to movement during CPR)
IO - Trochanteric fossa in the femur (good in Small A)
IT - Give as chest inflates to distribute drug

11
Q

Describe electrical defibrillation in CPR

A
  • Only way to deal with ventricular arrest
