Terms | Definitions |
|---|---|
 kinetic energy, and potential energy | the 2 types of energy (mechanical) |
| kinetic energy | what is energy in motion |
| formula for work | W=FxD, work=force x distance |
| power | measure of the rate at which work is being performed, P=W/T |
| joules | unit of energy or work, 1J=1N |
| kinetic energy equation | KE=1/2(mv2) [2 is squared] |
| potential energy equation | PE=mgh |
| melting point | the temperature at which a solid converts to a liquid |
| freezing point | the temperature at which a liquid is changed to a solid state |
| boiling point | temperature at which a liquid converts to a gaseous state |
| evaporation | process in which liquid changes into the vapor state |
| latent heat | the amount of heat that must be added to a substance to cause a complete change of state |
| sublimation | process in which solid molecules completely bypass the liquid state and change to a gas |
| condensation | the opposite of evaporation, conversion of a substance from a gas to a liquid |
| kelvin to celsius formula | k-273 |
| celsius to kelvin formula | c+273 |
| celsius to fahrenheit formula | (9/5 x C) + 32 |
| fahrenheit to celsius formula | 5/9 (f-32) |
| 760 mmHg | the pressure of air at sea level |
| 47 mmHg | water vapor pressure at 37C (normal body temperature) |
| laminar flow | fluid flow in streamlines, normally associated with the movement of fluids through tubes with smooth surfaces and fixed radii, desired flow when giving treatment to a patient |
| turbulent flow | movement of fluid that become chaotic and the concentric layers seen with laminar flow is lost, occurs when viscosity of fluid increases sharply, the tubes radius varies, and when the tubes surface is rough and uneven |
| ASSS | american standard safety system |
| PISS | pin index safety system |
| DISS | diameter index safety system |
| 50 PSI | standard working PSI in medical gas |
| liquid O2 | the type of gas that lasts longer |
| conversion factor for E cylinder | .28 |
| conversion factor for H cylinder | 3.14 |
| conversion factor for G cylinder | 2.41 |
| minimum PSI to room outlet | 50 PSI |
| concentrators | provide O2, mainly for home use, 2 types, molecular seive and membrane |
| max filling/service pressure of med gas tank for E & H | 2000 psi for E, 2200 psi for H, add 10% to psi if approved |
| color for oxygen | green |
| color for carbon dioxide | gray |
| color for nitrous oxide | light blue |
| color for helium | brown |
| color for heliox | brown and green |
| color for compressed air | yellow |
| bourdon flowmeter | pressure gauge used on E tanks |
| thorpe tube flowmeter | pressure gauge used for gas outlet in patient rooms, gas suspends steel ball |
| nasal cannula | O2 delivery device characterized by small hollow prongs that are inserted into the external nares, 1-6 L/M, low flow |
| venturi mask | O2 mask that uses a venturi device to provide precise concentrations of high flow O2 to a patient, a.k.a. air entrainment masks |
| oxygen hood | clear plastic enclosure that is placed around a pediatrics head to deliver oxygen therapy, high flow |
| simple O2 mask | low flow mask to deliver O2, 35% to 50% FIO2 at 5 to 10 L/M...no less than 5 L/M |
| partial-rebreathing mask | low flow O2 mask with an attached reservoir bag that allows patient to reinhale the first third of their exhaled breath, delivers FIO2 of 0.4 to 0.6 with O2 flows of 6 to 8 L/M |
| nonrebreather mask | low flow O2 mask similar to a partial-rebreather except they have one way valves, one between the bag and mask, and the others at the exhalation port of the mask, theoretically provide 100% O2, but in actual practice deliver an FIO2 of 0.6 to 0.8 |
| laplace's law | P=2(ST/r) |
| boyle's law | V1P1=V2P2 or V1/V2=P2/P1, temperature is constant so they cancel out |
| charle's law | V1/T1=V2/T2, pressure is constant so they cancel out |
| gay-lussac's law | P1/T1=P2/T2, volume is constant so they cancel out |
| combined gas law | P1V1/T1=P2V2/T2 |
| dalton's law | PO2=(total barometric pressure)(gas), example PO2=(760)(0.21).....PO2=159 mm Hg |
| avogadro's law | 6.02x10 to 23rd power |
