When an animal is too light, you... |
Apply PPV until breathing. Don't exceed 12mm on manometer. |
|
|
If animal is too deep, you... |
- turn off vaporiser |
|
|
After turning off vaporiser, you |
- check heart and O2 |
|
|
After checking heart and O2, you |
- detach animal, block tube and open pop off valve |
|
|
After detaching animal, blocking tube and opening pop off valve, you |
- flush iso out of bag |
|
|
After flushing the iso out of the bag, you |
- close valve and half refill bag with O2 |
|
|
After closing the valve and half refilling bag with O2, you |
- reattach animal and apply IPPV in 6 second intervals |
|
|
After applying IPPV and seeing animal reflexes reappear, you |
- turn iso back on and adjust pop off valve |
|
|
Part that holds O2, and part that indicates pressure |
Gas cylinder and pressure gauge |
|
|
Part which allows anaesthetist to set O2 flow rate |
Flow meter |
|
|
Introduces pure O2 to circuit |
Oxygen flush button |
|
|
Converts liquid anaesthetic to gas and controls amount mixed |
Vaporiser |
|
|
Ensures unidirectional flow of gas in circle (rebreathing) system |
Flutter valves |
|
|
Connects to inspiratory and expiratory tubes of circle system |
Y connector |
|
|
Allows animal to breathe easier from reservoir of gas, and can be used to manually breathe for the animal |
Reservoir bag |
|
|
What is the minimum volume of a reservoir bag to be used for a patient |
60ml/kg |
|
|
Used only in rebreathing system, removes CO2 from expired gases |
Soda lime + canister |
|
|
When should soda lime be changed? |
When half the canister has been consumed |
|
|
When should a pop off valve be fully open? |
When using a non-rebreathing system |
|
|
When should a pop off valve be partially open? |
When using a rebreathing system |
|
|
When should a pop off valve be closed? |
For leak tests and manual breathing |
|
|
The scavenger system should attach to? |
Pop off valve |
|
|
What does the scavenger system do? |
Collects expired gases |
|
|
Measures pressure in system |
Manometer |
|
|
Advantage of rebreathing system |
Warms and humidifies incoming air using previously expired air and exothermic reaction with soda lime |
|
|
Disadvantages of rebreathing system |
1. More dead space - bad for smaller animals 2. Excess weight and bulk of hoses 3. unidirectional valves cause some resistance in breathing |
|
|
Animal size, valve position and flow rate of a rebreathing system |
> 10kg, partially open, 50mL/kg |
|
|
Animal size, valve position and flow rate of a non-rebreathing system |
< 10kg, fully open, 300mL/kg |
|
|
Why use IV fluids during anaesthesia? |
Replace blood/fluid losses in surgery Correct acid-base disorders Flushes anaesthetic out of blood for quicker recovery after surgery |
|
|
IV fluid rate under anaesthetic |
10mL/Kg/hr |
|
|
Calculation for ET tube size of normal conformation animal |
Size= √(5×weight) |
|
|
Estimate for tube size and length |
Size: distance between nostrils. Length: measure to thoracic inlet |
