Anesthetic Equipment Lab Flashcards
(30 cards)
How do you perform a high pressure leak test
Turn tank on by turning tank outlet valve and note tank pressure reading. Then turn tank off. Check gauge in one hour
At what pressure should we change the tank
100 to 200 psi
At what pressure should we call Oxymed
500psi
What is the purpose of the oxygen cylinder
Compressed gas so large amount stored in small cylinder.
What is the purpose of the tank outlet valve
Allows oxygen to flow into the machine when open
What is the purpose of the tank pressure gauge
Pressure of gas remaining when opened
What is the purpose of the pressure reducing valve
Almost constant flow of gas into machine and reduces pressure to 40 to 50 psi
What is the purpose of the oxygen line
For freestanding cylinders it transports oxygen to anesthetic machine
Why do we do a high pressure leak test
To check for leaks between the gas tank and the flowmeter
What is the purpose of the flow meter
Turns on or shuts off oxygen flow through machine. Decreases gas pressure to 15 psi
What is the purpose of the vaporizer
Vaporizes liquid anesthetic to gas
What is the purpose of the indicator window
Allows viewing of liquid anesthetic levels
What is the purpose of the oxygen flush valve
To dilute the line with oxygen
What is the purpose of the fresh gas inlet
Mix of oxygen and anesthetic has
What is the purpose of the reservoir bag
Stores gas, ensures ET tube is in trachea, allows delivery of oxygen
What is the function of the pop off valve
Allows access gas to exit the system
What is the function of the scavenger
Collects and disposes waste gas
What is the function of CO2 absorber
Absorbs co2 from rebreathed air
What is the function of the pressure manometer
Measures gas pressures in breathing system
What is the purpose for a low pressure leak test
Checks for leaks from the anesthetic machine to breathing circuit at 15 psi
What is the induction rate for the circle system
100-200 ml/kg/min
What is the induction rate for the Bain system
130-300ml/kg/min
What is the maintence rate for the circle system
25-50ml/kg/min
What is the maintenance rate for the Bain system
140-200ml/kg/min
