1

Describe a monitoring record

- Legal document
- Record of drugs, patient risk, events occuring, and recovert etc

2

What are 5 factors that you can monitor for anaesthesia

- Muscle relaxation
- Eye rotation and pupil dilation
- CRT
- Core temp
- Anal tone

3

Describe pulmonary monitoring

Breathing rate, effort and rhythm
(observe bag and chest)
Spirometry = reliable

4

What does CaO2 measure?

O2 content of the blood

5

What methods can be used to assess oxygen delivery?

CaO2, MAP, Respiration and CV function

6

Describe pulse oximetry and what it can tell us

- Infra red transmitter and reciever
- Measures absorption of light
- Oxygenised haem absorbs more IR and red light
- Correlate % abs with % oxygenated Haem

7

Describe two ways in which pulse can be assessed

- Peripheral pulse monitoring
- Femoral, dorsal, mediolateral, lingual etc

8

What methods can be used to measure Arterial Blood Pressure

Non invasive, invasive, doppler

9

Describe Doppler assessment

- Prezoelectric crystal placed over artery
- Cuff placed proximally to this
- Audible and visible reading

10

Describe non invasive blood pressure monitoring

- Expensive and unreliable in cats and small dogs

11

Describe invasive blood pressure monitoring

- Artery cannulation
- Gives systolic, mean and diastolic Blood pressure
- Can use auricular, dorsal pedal and facial arteries

12

Describe central venous pressure monitoring

- Jugular catheter
- Indicates filling pressure of the heart
- Increase in CVP = failing heart/volume overload
- Decrease in CVP= haemorrhage, blood pooling, incomplete fluid therapy

13

Describe capnography

- Measures CO2 concentration in the breath and plots CO2/time
Measured by : Infrared mass spec and main and side stream sampling
- Assumes that alveoplar CO2= arterial CO2

14

What can an increased CO2 reading during anaesthesia

- Rebreathing = increase FGF rate)
- Exhaustion of soda lime
- Pyroxia

15

What can be taken from a reduced CO2 reading during anaesthesia?

Cardiac arrest (first sign)
Misintubation

16

What is bucking ventilation?

Animal trying to breathe for itself

17

What is a curare cleft

Where disconcordance in the respiratory muscle leads to intake of breath within process of exhailing

18

Give three ways in which temperature can be regulated in a patient under anaesthesia

- Bubble wrap, hot water beds and lamps

19

What affect can hypothermia have on a patient under anaesthesia and why may this happen

Prolonged recovery
- Reduced metabolism and circulation
- Increased O2 demand
- Vasodilation, lack of shivering, open body cavity etc

20

Describe three ways in which the renal system can be supported during anaesthesia

- Fluids
- Beta + something
- Always urinary catheter horses!!
