Pao2 conversion
WebPaO2 – FiO2 ratios PaO 2: FiO 2 is the ratio of inspired O2 to arterial O2, as a measure of diffusion. PaO 2 is in mmHg . FiO 2 is in fractions (i.e. on 50% O 2 your FiO 2 is 0.5) The ratio is (PaO 2 in mmHg) divided by (FiO 2 in fractions) Lets say you are generally aiming for a PaO 2 of 100mmHg. If you are maintaining 100 PaO 2 on 21% FiO 2 ... http://www-users.med.cornell.edu/%7Espon/picu/calc/o2satcal.htm
