Q

If no breathing or circulation, immediately begin CPR. Why is time crucial for arrested patients?

A

Longer time until CPR = less likely to recover, more likely to have brain damage

Q

Some argue abdominal compression increase CPR success rate. What are the disadvantages of this?

A

Needs more people

Can damage liver or spleen

Q

What are the 2 parts to CPR? What ratio do you do these in if alone?

Changeover people (if 2 people)
Do mouth to snout (if alone)

Q

What should you do for the ventilation part to CPR?

A

Use ET tube IPPV - intermittent positive pressure ventilation using O2 and reservoir bag

17
Q

Why should you not fully squeeze the reservoir bag?

A

Over inflates and damages lungs - emphysema

18
Q

What are the disadvantages of blowing down the ET tube?

A

only 15% oxygen

19
Q

If no ET tube is available. How is mouth to snout done?

A

Seal off mouth with hands

Do 2 breaths to every 30 chest compressions or 10 breaths per minute

20
Q

What is the tidal volume and inspiratory period when doing ventilation?

A

Inflate bag 10mls/kg

1 second

21
Q

How does the cardiac pump theory work?

A

Ventricles compressed directly between ribs (lateral recumbency) or between sternum and spine (dorsal recumbency
Blood forced from heart to lungs and periphery
Relaxation returns blood to ventricles

22
Q

How does the thoracic pump theory work?

A

Increased intrathoracic pressure compresses the aorta and collapses the vena cava
Forces blood out of the thorax
Elastic recoil of chest decreases intrathoracic pressure
Blood flows from periphery into thorax

23
Q

What position should round chested dogs (e.g. labrador) be when doing CPR? What theory is easiest?

A 
Lateral recumbency (either side)
Thoracic pump theory
24
Q

What position should narrow chested dogs (e.g. greyhound) be when doing CPR? What theory is easiest?

A

Lateral recumbency

Cardiac pump theory

25
Q

What position should barrell chested dogs (e.g. bulldog) be when doing CPR? What theory is best?

A

Dorsal recumbency

Cardiac pump theory

26
Q

What position should dogs <10kg with compliant chest and small cats be in for CPR? What theory applies?

A

Lateral recumbency
Cardiac pump theory
Use thumb and forefinger

27
Q

What position should large cats and small dogs <10kg with non-compliant chests be in for CPR? What theory applies?

A

Lateral recumency
Cardiac pump theory
Two handed heart compressions

28
Q

When is cardiac pump theory used?

A

Always except in round chested dogs (thoracic pump theory)

29
Q

What position should all animals be in for CPR?

A

Lateral recumbency

Except barrel chested dogs (dorsal recumbency)

30
Q

What should somebody else be doing whilst chest compressions and ventilation take place?

A

Check femoral pulse to see if adequately doing chest compressions

31
Q

If crashing during anaesthetic, what should you do first?

A

Turn off anaesthetic as suppresses respiratory and cardiac system
Turn on oxygen
