Complete Solutions New Update
DISS - Answers -✔✔ diameter indexed safety system, uses differend thread pitches, to
prevent connection of wrong tanks or accidental interchange of low-pressure medical
gas connectors less than 200psi
compressors (what do they do?) - Answers -✔✔ 1. provide "oil free" compressed air to
power equipment
2. mix with oxygen to provide lower O2 concentrations
Piston Compressor - Answers -✔✔ compressor, driven by an electric motgor, carbon or
teflon piston rings seal the pison, eliminating the need for oil, used to run ventilators
Centrifugal Compressor - Answers -✔✔ Compressor using centrifugal force, used to
run ventilators
H Tank - Answers -✔✔ 244 cubic feet of O2....Fudge Factor= 3.14 Weighs 135 lbs.
E Tank - Answers -✔✔ 22 cubic feet of O2 Fudge Factor = .28 Weighs 16 lbs.
ASSS - Answers -✔✔ American Standard Safety System used for larger tanks
(F- M-G-H tanks)
PISS - Answers -✔✔ Pin Index Safety System, used for small tanks AA-E tanks
Compressed Air - Answers -✔✔ Pressurized and Filtered air
3 types of Compressors - Answers -✔✔ Piston, Centrifugal(used for ventilators) and
Diaphragm
Concentrators - Answers -✔✔ Provide O2-powered by electricity, used mostly in
nursing homes. Two types, Molecular seive and Membrane
Diaphragm Compressor - Answers -✔✔ utilize a flexible diaphragm driven by an
electric motor to compress the air. Typically used to power small nebulizers, not used
for amounts of compressed air
Oxygen tank, color - Answers -✔✔ Green
Carbon Dioxide tank, color - Answers -✔✔ Gray
Nitrous oxide tank, color - Answers -✔✔ Blue
, Helium tank, color - Answers -✔✔ brown
Nitrogen tank, color - Answers -✔✔ Black
air tank, color - Answers -✔✔ yellow
Molecular Seive Concentrator - Answers -✔✔ Looks like a strainer, better @ delivering
constant FiO2
Membrane Concentrator - Answers -✔✔ aka, enricher...filters nitrogen out of air
Liquid reservior system - Answers -✔✔ liquid O2, found in hospitals, bulk supply
system
Agency that classifies cylinders - Answers -✔✔ DOT: department of transportation
Tanks made of ... - Answers -✔✔ High strenght Steel, formed under high heat, molded
into shape 3AA table, heat treated,
Tank duration formula - Answers -✔✔ PSI Pressure x Cylinder Factor / Flow
BVM - Answers -✔✔ Bag Valve Mask
What to you do to large tanks (subtract/add what?) - Answers -✔✔ subtract 500
Inspiratory - Answers -✔✔ taking air in
"hungry" - Answers -✔✔ patient needing air
One cubic foot of O2 = - Answers -✔✔ 28.3 liters
regulators (combo of what?) - Answers -✔✔ combo of flowmeter and reducing valve,
(All one piece)
Uncompensated Thorpe Tube O2 flowmeter (what position, prevents change or does
not prevent change in downstream resistance?) - Answers -✔✔ mostly used for giving
breathing treatments..operates only in upright position
-Uncompensated DOES NOT prevent change in downstream resistance to change the
flow
