Anesthesia machine 2 Flashcards
(60 cards)
Identify the BEST practices for handling gas cylinders. (select 2).
a. laying the cylinder on its side when changing the cylinder on the anesthesia machine
b. oiling cylinder valves every six months
c. placing two washers between the cylinder and the hanger yoke assembly
d. removing the plastic cover on the port when installing the cylinder
a. laying the cylinder on its side when changing the cylinder on the anesthesia machine
d. removing the plastic cover on the port when installing the cylinder
____________ is the most delicate part of the cylinder.
The cylinder valve
Gas cylinders should be stored
in the upright position & secured. If you’re changing the cylinder on the anesthesia machine, it’s ok to lay the cylinder on its side temporarily
If you remove a cylinder from the anesthesia machine but you don’t have a replacement
then you’ll need to insert a yoke plug
If you open the cylinder and hear a “hissing” sound, there’s
a leak. Your first step is to tighten the connection
DO NOT _________between the cylinder and the hanger yoke assembly as this can defeat the PISS
place more than one washer
Never take a cylinder into the _______________ unless it’s made of a non-magnetic material, such as ___________
MRI scanner; aluminum
These are oxidizers:
oxygen and nitrous oxide
The fire triangle includes
an oxidizer, fuel, and igniter
Gas cylinder should never be exposed to temperatures
above 130 F or 57 C
This will increase the risk of fire and should never be done.
Do not oil the cylinder valve
You should remove ____________ from the port before installing the cylinder. Failure to do so may ____
the plastic cover; may obstruct gas flow when the cylinder is turned on
The fire triad consists of
an oxidizer, fuel, and an igniter
If there’s a fire, a _____________ built into the cylinder opens, allowing the cylinder to empty its contents in a slow and controlled way.
safety relief device
Examples of safety relief devices include
a fusible plug that melts at elevated temps- made from Wood’s metal: bismuth, lead, tin, & cadmium (BLT w/ cheese)
valve that opens at elevated pressures
frangible disk that ruptures under pressure
Who sets the standards for the required components of the anesthesia machine?
American Society for Testing and Materials (ASTM)
Who created the 1993 Anesthesia Machine Pre-Use Checkout procedures?
Food and Drug Administration (FDA)
Who sets the standards for acceptable occupational exposure to volatile anesthetics?
Occupational Safety and Health Administration (OSHA)
Who sets the standards for compressed gas cylinders?
US Department of Transportation (DOT)
A cylinder must be tested
every 5 years
The cylinder is tested for leaks and the ability to maintain structural integrity, this is done by subjecting the cylinder to
1.66 times its service pressure
What 7 items does the US DOT require on the cylinder label?
- Government agency (DOT)
- Type of metal used to construct the cylinder
- Maximum filling pressure (psi)
- Serial number
- Manufacturer
- Owner
- Date of the last inspection
The oxygen pressure failure device activates when the (Select 2):
a. oxygen pressure in the supply line is less than 20 psi
b. the oxygen pipeline contains nitrous oxide
c. FiO2 in the inspiratory limb is less than 21%
d. Oxygen tank is exhausted
a. oxygen pressure in the supply line is less than 20 psi
d. oxygen tank is exhausted
The ________ monitors for low oxygen pressure in the anesthesia machine.
oxygen pressure failure device (failsafe device)
