Anaesthesia Flashcards
SAA01
The veterinary surgeon wants to anaesthetise a cat for ovariohysterectomy.
Using the equipment available, select, assemble and attach the most appropriate
anaesthetic breathing system for this patient.
As this is the first induction of the day, you will also need to check that the anaesthetic
machine is ready for use. Explain to the examiner the checks that you are making.
For this patient you are required to calculate:
a. Tidal volume (X ml/kg)
b. Minute volume
c. Fresh gas flow per minute
The patient has a pre-anaesthetic respiration rate of X breaths per minute

- Correct breathing system assembled correctly
- Breathing system attached correctly to machine and scavenging
- Open the oxygen cylinder valve (slowly anticlockwise)
- Check the registered quantity of oxygen on the pressure dial
- Turn on the oxygen flowmeter control to check smooth function
- Turn off oxygen flowmeter control
- Press emergency oxygen flush button
- Attach ‘in-use’ label to oxygen cylinder
- Check the vaporiser percentage dial to ensure it turns easily
- Check the level of the volatile anaesthetic agent in the vaporiser and
take appropriate action - Check for leaks in the breathing system
- Fully open APL valve and leave open
- Leave anaesthetic machine ready for use (i.e. oxygen should be
switched on and anaesthetic breathing system attached). - Tidal volume calculation correct (15 x BW)
- Minute volume calculation correct (TV X RR)
- Fresh gas flow calculation correct (MV X 2.5-3)
- Correct units of measurement used for final answer
SAA02
A patient has been admitted with a suspected ruptured diaphragm. The veterinary surgeon wants to anaesthetise the patient and may require you to provide assisted ventilation during anaesthesia.
Using the equipment available, select, assemble and attach the anaesthetic breathing system for this patient.
As this is the first induction of the day, you will also need to check that the anaesthetic
machine is ready for use. Explain to the examiner the checks that you are making.
For this patient you are required to calculate:
a. Tidal volume (X ml/kg)
b. Minute volume
c. Fresh gas flow per minute
The patient has a pre-anaesthetic respiration rate of X breaths per minute.

Using the equipment available, select, assemble and attach the anaesthetic breathing system for this patient.
As this is the first induction of the day, you will also need to check that the anaesthetic
machine is ready for use. Explain to the examiner the checks that you are making.
For this patient you are required to calculate:
a. Tidal volume (Xml/kg)
b. Minute volume
c. Fresh gas flow per minute
The patient has a pre-anaesthetic respiration rate of X breaths per minute.

SAA04
The veterinary surgeon wants to anaesthetise a dog for dental treatment.
Using the equipment available, select, assemble and attach the anaesthetic breathing system for this patient.
Select and prepare the most appropriate endotracheal tube.
