What are medical gas regulated for? - ANS -1. Regulated for production standards.
2. Regulated for storage criteria
3. Regulated for delivery method
What is the function of the compressed gas association? - ANS --CGA-
Sets standards and safety guidelines for compressed gas.
What is the function of the national fire protection association? - ANS -- NFPA -
Creates standards for the storage of flammable and oxidizing gases
Sets standards for the design, construction, placement, and use of bulk O2 system.
What is the function of the department of transportation? - ANS -- DOT -
Responsible for CGA - compressed association.
What is the function of the food and drug administration? - ANS -- FDA -
Sets purity level of medical gases.
What is the function of the bureau of medical devices? - ANS -- BMD -
Provides standards for and regulates medical devices.
What is the function of the occupational safety and health organization? - ANS -- OSHA -
Sets standards for safe and healthy work environment.
How are medical gas classified? - ANS -Based on their potential fire risk.
What characteristics of medical gas are nonflammable -will not burn-? - ANS -N2 -
Nitrogen
CO2 - Carbon Dioxide
He - Helium
What characteristic of medical gas supports combustion? - ANS -O2 - Oxygen
N2O - Nitrous Oxide
, Air
O2/N2
O2/CO2
He/O2
What characteristic of medical gas is flammable? - ANS -Cycloproprane
Ethylene
Define anesthetic gas and medical gases associated with it. - ANS -Are combined with
oxygen to provide anesthesia during surgery.
-Cyclopropane, Ethylene, Nitrous Oxide.
Define lab gases and medical gases associated with it. - ANS -Are used for equipment
calibration and diagnostic testing. - Limited therapy
-Carbon dioxide, helium, nitrogen
Define therapy gases and medical gases associated with it. - ANS -Are used to relieve
symptoms and improve oxygenation of patients with hypoxemia.
- AIR, He/O2, Oxygen, O2/CO2, O2/N2
What are the characteristic of carbon dioxide - CO2? - ANS -1. Colorless and odorless
gas with a specific gravity of 1.52
2. 1.5 times as heavy as air
3. Does not support combustion.
4. Produced via heating limestone/ contact with H20
5. FDA purity - 99.0
What are the characteristics of helium - He? - ANS -1. Very light, only gas lighter is
hydrogen
2. odorless, tasteless, inert
3. Nonflammable
4. Produced from natural gas by liquefaction.
5. FDA purity - at least 95
6. STPD of 0.1785
What are the characteristic of air? - ANS -1. Colorless, odorless
2. 1.29 g/l density
3. Medical grade air produced by filtering atmospheric air.
4. Gas mixture consisting of 20.95 O2, 78.1 N2, and 1 trace gas mainly argon.
Air must be free of what to be used as a medical gas? - ANS -Air must be dry and free oil
or particulate contamination. For avoidance of oil or particulate contamination, medical
air compressors have air inlet filters and polytetrafluroethylene Teflon piston rings as
opposed to oil lubrication.
