week 1 L 3

Question 1

Explain the follwoing Abbreviations:
PB
PO2
PCO2
PN2
FO2
FCO2

Answer 1

1. PB= atmospheric pressure
2. PO2 = partial pressure of oxygen
3. PCO2= partial pressure of carbon dioxide
4. PN2= partial pressure of nitrogen
5. FO2= fractional concentration of oxygen
6. FCO2= fractional concentration of carbon dioxide

Question 2

Daltons law of partial pressure

Answer 2

PB= PO2 + PCO2 + PN2
Partial pressure = fractional concentration x total pressure PO2= FO2(21%) x PB(760 mmHG)
FCO2 (0.04%)

fractional concentration applies to gases only
Concentration applies to

Concentration applies to gases in liquids like blood
