Subtract 1 from the ATA then multiply by 14.7= PSIG
Convert ATA to mmHg
Multiply ATA by 760 = mmHg
Convert mmHg to ATA
Divide the mmHg by 760 = ATA
Convert mmHg to %
Divide the mmHg by 7.6
Convert % to mmHg
Multiply the % by 7.6
Convert Celsius to Kelvin
Add 273
Convert Fahrenheit to Rankin
Add 460
To find the PP of Inspired Oxygen?
Multiply the Total Pressure by % of gas(FIO2)
PO2=PTotal x FIO2
Find the Arterial Partial Pressure of inspired oxygen.
Subtract the partial pressure of water (PH2O =47) from the PTotal. Multiply that by the FIO2 then subtract the partial pressure of carbon dioxide in the alveoli (PCO2)
PAO2=[(PTotal-PH2O)xFIO2]-PCO2
Dalton's Law
PTotal=ppN2 +ppO2 +PP of other gases.
Henry's Law formula
P1/A1 = P2/A2
A=amount ie: Liters, CC etc.
Gay-Lussac's Law Formula
P1/T1 = P2/T2
Temp is absolute & Volume is constant IE: scuba tank.
Charles Law Formula
V1/T1 = V2/T2
Temp is in absolute & Pressure is constant because container is flexable IE:balloon at Sea Level
Boyle's Law Formula
P1 x V1 = P2 x V2
General or Combined Gas Law Formula
(P1xV1)/T1 = (P2xV2)/T2
