1. Convert FSW to PSIG
Multiply FSW by .445
2. Convert PSIG to FSW
Divide PSIG by .445
3. Convert FSW to ATA
Add 33 to the FSW then divide by 33 = ATA
4. Convert PSIG to ATA
Add 14.7 to the PSIG then divide by 14.7 = ATA
5. Convert ATA to FSW
Subtract 1 from the ATA then multiply by 33 = FSW
6. Convert ATA to PSIG
Subtract 1 from the ATA then multiply by 14.7= PSIG
7. Convert ATA to mmHg
Multiply ATA by 760 = mmHg
8. Convert mmHg to ATA
Divide the mmHg by 760 = ATA
9. Convert mmHg to %
Divide the mmHg by 7.6
10. Convert % to mmHg
Multiply the % by 7.6
11. Convert Celsius to Kelvin
12. Convert Fahrenheit to Rankin
13. To find the PP of Inspired Oxygen?
• Multiply the Total Pressure by % of gas(FIO2)
• PO2=PTotal x FIO2
14. 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
15. Dalton's Law
PTotal=ppN2 +ppO2 +PP of other gases.
16. Henry's Law formula
• P1/A1 = P2/A2
• A=amount ie: Liters, CC etc.
17. Gay-Lussac's Law Formula
• P1/T1 = P2/T2
• Temp is absolute  & Volume is constant IE: scuba tank.
18. Charles Law Formula
• V1/T1 = V2/T2
• Temp is in absolute  & Pressure is constant because container is flexable IE:balloon at Sea Level
19. Boyle's Law Formula
P1 x V1 = P2 x V2
20. General or Combined Gas Law Formula
(P1xV1)/T1 = (P2xV2)/T2
