Front (Question)

What is an aneroid gauge?

Back (Answer)

A gauge without liquid

Front (Question)

What is a bourdon gauge?

Back (Answer)

A type of aneroid gauge; no liquid inside

Front (Question)

A bourdon gauge measures ___ and is seen on what types of tanks?

Back (Answer)

Gas pressures (specifically measures pressure difference between the pressure exerted by the gas in the compressed cylinder vs. atmospheric pressure) Seen on O2, air, and N2O tanks

Front (Question)

When the bourdon gauge reads ‘0’, is there any pressure left in the tank?

Back (Answer)

YES—once it reads 0, it still has the equivalent of atmospheric pressure in there (14 psi of atmospheric pressure remains)

Front (Question)

A tank of gas has a gauge that reads 45 psi. If the atmospheric pressure at that time is 14 psi, how much gas is really in the tank?

Back (Answer)

P total = P gauge + P atmosphere P total = 45 + 14 = 59 psi

Front (Question)

1 atm = ___ psi

Back (Answer)

14 psi

Front (Question)

1 atm = ___ torr = ___ mm Hg

Back (Answer)

1 atm = 760 torr = 760 mm Hg

Front (Question)

Barometer is an instrument used to measure ___

Back (Answer)

Atmospheric pressure

Front (Question)

Manometer is an instrument used to measure ___

Back (Answer)

Pressure differences

#10

Front (Question)

What law is the basis of pulse oximetry?

Back (Answer)

Beer Lambert’s Law

#11

Front (Question)

Pulse ox measures the difference between background absorption in ___ and peak absorption during ___

Back (Answer)

Diastole; systole

#12

Front (Question)

Infrared light— ___ nm; measures ___; corresponds with ___% sat

Back (Answer)

940 nm; measures oxyhemoglobin; corresponds with 100% sat

#13

Front (Question)

Red light— ___ nm; measures ___; corresponds with ___% sat

Back (Answer)

660 nm; measures deoxyhemoglobin; corresponds with 50% sat

#14

Front (Question)

Carboxyhemoglobin— ___ binds to hemoglobin instead of O2; shows SPO2 reading of ___; use ___

Back (Answer)

CO; SPO2 reading of 100% (inaccurate); use co-oximeter

#15

Front (Question)

Methemoglobin

Back (Answer)

Fe 2+ converts to Fe 3+ form; O2 cannot be transported by iron in hemoglobin

#16

Front (Question)

Methemoglobin is caused by what (6) things?

Back (Answer)

• Nitrates • Nitrites • Sulfonamides • Benzocaine spray • Nitroglycerin • Nitroprusside

#17

Front (Question)

Methemoglobin absorbs ___ at both wavelengths

Back (Answer)

Equally

#18

Front (Question)

Methemglobin shows sat of ___%

Back (Answer)

85%

#19

Front (Question)

Treatment for methemoglobinemia

Back (Answer)

Methylene blue or ascorbic acid

#20

Front (Question)

What two things do NOT affect pulse ox readings?

Back (Answer)

Fetal hemoglobin and bilirubin

#21

Front (Question)

___ is the basis behind non-invasive blood pressure technology

Back (Answer)

Oscillometry

#22

Front (Question)

___ is used in pressure monitoring with transducers

Back (Answer)

Piezoelectric technology

#23

Front (Question)

Electricity is defined as the effects produced by ___

Back (Answer)

Moving charges

#24

Front (Question)

Proton =

Back (Answer)

Positive charge
