Blend anesthetic gas mixture

Allow ventilation of patient's lungs

500

What are the five functions of oxygen in the anesthesia machine?

What are 

Go to oxygen flowmeter

Go to O2 Flush

Sir Ideal Newton

100

These three formulas combine to make ideal gas law

Charles, Boyles, Gay-Lussac

200

With constant temperature and amount of substance, the following relationship is true for ideal gases

P1*V1 = P2*V2

(Boyle's Law)

300

Newton's second law comes up with this equation

F =m*a

400

This law states at a given temperature, the amount of gas dissolved in a given liquid is directly proportional to the partial pressure of the gas in equilibrium with liquid

Henry's law

500

The amount of heat energy to raise the temperature of an object by 1 Kelvin

Heat capacity

100

This portion of the electrical cord prevents leakage 

Ground wire

200

This is the most important question when determining if a patient's pacemaker should be reprogrammed before surgery

Is the patient pacemaker dependent?

300

This system is the last to see effects as a result of experiencing 60 Hz currents

Respiratory center

400

These types of surgeries would benefit greatly from utilization of bipolar electrosurgical units

100

These weak forces are exerted by liquid molecules onto another 

Van der Waals Forces

200

As vapor pressure increases, the boiling point will then

Decrease

300

This form of heat loss accounts for the largest percentage of normal heat loss from the body

Radiation

400

Le Chatelier's Principle dictates that more inhalational agent will dissolve in the blood if the patient experiences this common perioperative complication
