AGM

Question 1

Joule Thompson effect

Answer 1

When compressed gas is released into free space the process is adiabatic and cooling occurs

Question 2

O2 tank psi and L

Answer 2

600L
1900 psi

Question 3

Nitrous oxide tank numbers

Answer 3

1600 L
750 psi

Question 4

02 tank numbers

Answer 4

660 L

2000psig

Question 5

Nasal cannula <5L/min conversion to fio2

Answer 5

1 L/min flow rate can increase FiO2 to 24%,
2 L/min to 28%,
3 L/min to 32%,
4 L/min to 36%,
5 L/min to 40%,
and 6 L/min to 44%.

This may be changing, new studies say inspiration flow rate has a greater impact on fio2 than NC flow rate for low flow O2 delivery

Question 6

Material of MRI safe O2 tanks

Answer 6

Aluminum, apparently its non-ferrous

Question 7

How many mcg/ml in 1:100,000

Answer 7

10 mcg/ml

Question 8

How many mcg in 1:200,000

Answer 8

5 mcg/ml

Question 9

How many mcg in 1:1,000,000

Answer 9

1 mcg/ml

Question 10

Example of Boyles law

Answer 10

Bag mask ventilation

Pressure and volume

Question 11

Standardization acronym for pipeline gas

Answer 11

DISS

Question 12

Standardization acronym for cylinder attachments

Answer 12

PISS

Question 13

Henrys law

Answer 13

Amount of dissolved gas in a liquid is directly proportional to the partial pressure of the gas above it

Carbonation-opening a beer… the gas in the beer wants to equilibrium with the new atmosphere

Henry Heineken

Question 14

Rough estimate of paO2 based on fio2

Answer 14

PaO2=5xfiO2

Question 15

Alveolar gas equation

Answer 15

(Pb-Ph2o) FiO2-PaCO2/R=PAO2

R=ratio of o2/co2 being produced
Pb=atmospheric (760)
PH20=47

Question 16

Calculating TV

Answer 16

IBW* 7ml/kg

Question 17

Calculating IBW

Answer 17

W: 100+(5lbs per inch over 5 ft)

M: 105 + (6lbs per inch over 5 ft)

Question 18

Joule Thompson effect

Answer 18

Joule is cool

adiabatic cooling-property of gas changing temp with change in pressure

What the volume percent at 1 atm?

Answer 25

Vapor pressure of iso=240 mmHg =240/760*100= 31.4%

Question 26

Oops I made a mistake… high vapor pressure agent in low pressure vaporizer, what happens?

Answer 26
