 Convert FSW to PSIG Multiply FSW by .445 Convert PSIG to FSW Divide PSIG by .445 Convert FSW to ATA Add 33 to the FSW then divide by 33 = ATA Convert PSIG to ATA Add 14.7 to the PSIG then divide by 14.7 = ATA Convert ATA to FSW Subtract 1 from the ATA then multiply by 33 = FSW Convert ATA to PSIG 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/A2A=amount ie: Liters, CC etc. Gay-Lussac's Law Formula P1/T1 = P2/T2Temp is absolute  & Volume is constant IE: scuba tank. Charles Law Formula V1/T1 = V2/T2Temp 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 AuthorTomOkey ID272301 Card SetHyperbaric Conversions/Formulas.txt DescriptionConversions that are used in Diving and Hyperbaric Medicine Updated2014-06-06T13:22:26Z Show Answers
