Q

Any substance that permits the flow of electrons

A

Conductor

19
Q

Example of a conductor

A

Metals

20
Q

What do all stationary electric charges possess

A

Electric potential energy

21
Q

Electric potential energy is measured in what?

A

joules

22
Q

What is an example of something that has electric potential energy

A

Defibrillator (joules)

23
Q

What kind of wavelength does deoxygenated hemoglobin absorb?

A

visible red wavelength= 660 nm

24
Q

What kind of wavelength does oxygenated hemoglobin absorb?

A

infrared= 940 nm

25
Q

Every energized device or electrical circuit has the potential for producing an electric shock

T or F

A

True

26
Q

A relatively large amount of current flows through the body potentially resulting in injury or death

A

Macroshock

27
Q

A relatively small current is delivered externally and finds its way to the heart via a low resistance pathway

As little as 100 microA can cause v.fib

A

Microshock

28
Q

The longer the individual is in contact with a current, the greater the damage.

T or F

A

True

29
Q

If there is a surgical fire, what would you immediately pull?

A

ETT

30
Q

What is the oxidizer in 95% of surgical fires?

A

Oxygen. Heavier than air, it can accumulate around and under drapes

31
Q

Ways to prevent surgical fires

A

-Fire drills, education, trainings

-Avoid open air oxygen delivery (especially in head, neck, upper chest; turn O2 off when possible, ex: when surgeon closing)

-Administer supplemental O2 via ETT or LMA (closed systems=less fire risk than open- NC, mask)

-Limit supplemental O2 < 30%

-Turn O2 off 1 min before ESU

-Avoid pooling of prep solutions and allow to dry

-Continuous suction-scavenger systems

-Coat facial hair with water-soluble lubricant

-Use moistened sponges

-Laser resistant ETT’s for high risk cases

-Water and extinguishers immediately available
