Effects of altitude worsen with?
- Cold Upper latitudes
- PT that hace problems with low humidity and temp
temp
Guy Lussacs law
increase in temp = increase in presure
Decrease in temp = decrease in pressure
IE O2 tank pressure in cold/heat
Universal gas law
Combines Chalres and Boyles law
- Boyles Law-Increase volume = decrease pressure
- Charles Law - Temp and volume are proportional
Charles Law
Temp and volume are proportional
increase temp = increased volume
Boyles Law
Increased volume = Decreased pressure
Examples - BP cuffs, MAST, GI, ETT, IABP
IABP purges with ascent/decent
Henrys law
Gas in a liquid proportional to the gas above the liquide
Examples - CO2 in blood, The Bends, decompression
Gramhams Law
Define and effects
Define - Gas moves from high to low concetration
Example - Cellular gas exchange

Vent vs oxgyenation
What are the first adjustments on a vent if there is issues?
If it is a Vent problem- TV first then Resp Rate
If it is an oxgyenantion problem - FiO2 then PEEP
Traumatic dislocations
- Most Common Dislocation
Most Common spontaneous reocurrance
- hip
- Anterior shoulder
Brain Natriuretic Peptide or BNP
what is it used for and what are normal levels and elevated levels
It is a marker for heart failure
BNP is released by an over distended heart
Normal - less than 100
500-700 = heart failure

FAA bottle to throttle time and what FAA part?
At least 8 hours and it is part of FAA part 135
What are the other names for CVP?
Right aterial pressure (RAP)
What is the nomal CVP?
2-6 mmHg
What is the length in CM for a central catheter placement?
RA/CVP = 20-25 cm
RV = 30-35 cm
PA = 40-45 cm
Wedge = 50 cm or greater
Which port is used for measure CVP
Proximal or Blue port
