Vaporizers Flashcards
Involves a fractioning or splitting valve
plenum vaporizer
What vaporizer uses negative pressure rather than positive pressure to deliver anesthetic agent?
draw-over vaporizer
Age dependence of MAC of ______ matters. Age does not matter with ______.
sevo
desflurane
Vaporizer equation:
Who’s law?
Dalton’s Law
The temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
Vapor pressure = ATM pressure
Boils Law
What agent boils at room temperature?
desflurane
There are large variations in temperature/vapor pressure when allowed to boil at room temperature.
All fresh gas goes through the vaporizer. true or false?
true
Type of vaporizer that uses flow splitting valve that can be rotated to alter the ratio between bypass gas and vaporizer gas.
variable bypass vaporizer
Vaporizer that may contain a metal sieve that submerged. The bubbles produce large surface area and produce a saturated vapor at ambient pressure which can then be passed through a flowmeter into the FGF. Desflurane vaporizer is of this type.
Measured flow vaporizer
What type of vaporizer can not be tilted?
Tec type vaporizer
Vaporizer that has thermostat compensation valve in mixing chamber.
Tec 4
Has thermostat compensation valve in sump pump
Tec 5
What control unit behaves like an electronic variable bypass?
cassette Aladin Vaporizer
Datex
Des vaporizer
Tec 6
