Anesthetic Equipment Flashcards
1
Q
Pin Index Safety System
A
Prevents accidental mismatch of anesthetic gasses on machine
* oxygen can only go onto oxygen yolk
2
Q
NO2
Anesthetic Agent
A
- Gas and liquid mixture
- Tank registers 750 psi
- Pressure will not go below 750 until 80% full
- Empty = below 500 psi
- Oxygen required when in use to avoid hypoxia
3
Q
Pop-off Valves
A
- Allow for escape of waste gasses
- Prevents build up of excessive pressure
- Can be closed for IPPV
4
Q
IPPV
A
Intermittent Positive Pressure Ventilation
* bagging the patient
5
Q
Pop-off Occlusion Valve
A
- Will act the same as closing the pop-off valve when pressed
- Used as a quick way to check pressure of the machine
- May be used to “bag” the patient
6
Q
Flowmeter
A
- Controls the anesthetic gas entering the system
7
Q
Precision Vaporizers
A
- Calibrated for use with only one anesthetic liquid
- Allows for exact setting of % of anesthetic fresh gas
8
Q
Precision Vaporizers
Automatic Compensation
A
For changes in:
* total gas flow
* temperature
* respiratory rate of patient
* depth of anesthesia of patient
9
Q
Precision Vaporizer
Advantages
A
- Allows constant anesthetic vapor concentration delivered to patient
- Concentration less affected by external factors
10
Q
Non-Rebreathing System
A
- Used for those less than 15 lb
- Exhaled gasses removed by high fresh gas flow rates
- Not economical due to required high gas flow rates
11
Q
Re-breathing System
Types
A
- Closed
- Semi-Closed
12
Q
Re-breathing System
Closed
A
- Pop-off valve closed during operation
- Lowered margin of safety
- Use when needing to “breath” for patient
13
Q
Re-breathing System
Semi-Closed
A
- Pop-off valve partially if not fully open
- Most commonly used
- Uses greater gas flow
- Better margin of safety
14
Q
F/air Canister Lifespan
A
Recommended to replace after 12 hours
15
Q
Soda Lime Canister Lifespan
A
Recommend to change every 8 hours
* if expired during surgery: increase O2 to 3-5 L/min and complete case
