1

Why is monitoring anaesthesia important?

- Ensure appropriate depth of anaesthesia is given for the procedure

2

What 3 systems are prioritised when monitoring a patient?

- Cardio-vascular
- Central nervous
- Respiratory

3

What is the normal HR for dogs and cats?

- Dog = 70-140
- Cat - 100-200

4

What superficial arteries would you palpate? Name 2

- Femoral
- Sublingual
- Nasal
- Ulnar
- Palmar meta-carpal

5

When palapating the apex beat you realise the pulse is low. What is this commonly a sign of?

- Hypotension

6

What do stethoscopes help you monitor? (heart)

- Rhythm
- Rate
- Valve function
- Contractiblity

7

What is the best kind of stethoscope to use when monitoring a patients heart?

- oesophageal stethoscope

8

Name 2 methods of indirectly measure blood pressure/ pulse quality

- palpation
- oscillo-tonometry (pneumatic cuff)
- Ultrasonic (doppler)

9

Name a direct method of measuring blood pressure/pulse quality

transducer via intra-arterial catheter

10

What is the normal CRT and name a reason why it may be delayed

normal = <2 seconds
Delayed - hypotension or vasoconstriction

11

What are bright pink mucous membranes a sign of?

Hypercapnia

12

What are white mucous membranes a sign of?

Hypotension / blood loss

13

What are blue mucous membranes a sign of?

Cyanosis

14

How is haemoglobin saturation measured?

Pulse oximetery

15

How does pulse oximetry work?

- Red and infrared light beams used to detect presence of oxygenated arterial blood
Also measures pulse rate

16

How is perfusion monitored ? Name 2 methods

- Pulse pressure
- CRT
- Pulse oximetry
- Temperature (extremities in comparison to core)
- Urine output (if >1ml/kg/hr then perfusion is adequate)

17

How can looking at the surgical sight signify good perfusion or bad perfusion

Good perfusion = red blood oozing at site
Poor perfusion = dark oozing blood

18

What 3 things impact the depth of anaesthesia required?

- Procedure
- Activity during surgery
- Skin experience

19

How do you check a patients CNS activity

- Reflexes (cranial Nerve)

20

name 3 cranial nerve reflexes you should tests?

- Palpebral
- jaw tone
- Tongue curl
- Eye position
- Pupil diameter
- Corneal reflex
- Salivation (profuse in inadequate anaesthesia)
- Lacrimation (dry in deep anaesthesia)

21

What is the normal resp rate for cats and dogs?

Dog - 10-30
Cat - 20-30

22

What is the anaethetised resp rate for cats and dogs?

- Cat - 20-30
- Dog - 8-30

23

What impacts resp rate during anaesthesia? (3 things)

- Depth of anesthesia
- Surgical stimulation
- Drugs used

24

What drug causes apnoea

Propofol

25

What autonomic responses are expected to react during procedures?

- Heart rate
- blood pressure
- Pupil diameter
- CRT
- Skeletal muscle tone and response to toe pinching

26

How do monitor respiratory rate? (name 2)

- wrights respirometer
- Pulse oximeter
- AP alert
- Capnography
- Ausculation, counting, watching bag

27

How do you measure temperature in a patient

rectal thermometer
