CPR Flashcards
Describe cardiopulmonary arrest and give 3 effects
Characterised by acute failure of the respiratory and circulatory system
- Lack of O2 delivery to tissues
- Cellular death
- Cerebral Hypoxia
Describe three causes of CPA
Anaesthetic complications
Hypovolaemia
Severe trauma
Give three signs of CPA
Apnoea
No Palpable pulse
Bleeding stops at surgical site
Describe three preparations that can be made to deal with CPA
- CPR protocol
- Training of staff
- Crash cart/box
What would you start with if you were alone dealing with a case of Cardio Pulmonary Arrest
Compressions
Airway
Breathing
Describe the airway support that may be given in CPR
If aponea identified give 2-5 rescue breaths
- Can use ET (orotracheal intubation) tube or ambu bage
- May attempt emergency tracheostomy
Describe the breathing support that may be given in CPR
PPV
10 breaths per minute
Stop ventilation if spontaneous breathing returns
Describe the Circulation support for CPR
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
Describe two drugs that can be used to help treat an animal in CPA
- 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.
Describe three ways in which CPR drugs can be administered
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
Describe electrical defibrillation in CPR
- Only way to deal with ventricular arrest
