NU 624 Unit 9 - Fire in the Operating
Room Test With Solution
Triad of components required for ignition and propagation a fire - ANSWER
ignition source, fuel, and oxidizer
parts of the fire triad - ANSWER oxidizers (O2 and N2O), fuel (hair, drapes,
cosmetics, ETT), and ignition source (laser)
What are a highly effective and rapid source of ignition? - ANSWER lasers
Can ignition occur with O2 as the primary oxidizer at 21% or less? - ANSWER
yes
When is ignition potential amplified? - ANSWER in the presence of an
enriched oxidizer concentration.
anesthesiologists and laser operators must work together to ensure that the
________ possible FiO2 is used during all procedures - ANSWER lowest
common sources of fuel in OR - ANSWER ETT, other plastic items, drapes and
towels and alcohol based preparations.
less common fuels of fire in OR - ANSWER hair and skin ointments
