If you mean: 15 20 29 and 34 then it is 24.5 If you mean: 8 15 20 29 and 34 then it is 20
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
The alveolar air equation is: PAO2 = FiO2(Pb-47)-(PaCO2/R) where: PAO2 is the partial pressure of oxygen in alveoar gas; FiO2 is the fraction of inspired oxygen (on room air this would be 21%); Pb is the barometric pressure (at sea level this is 760 torr); 47 is the partial pressure of water vapor; PaCO2 is the partial pressure of carbon dioxide in blood; R is the V/Q mismatch, which is 0.8 unless stated otherwise So, if a person is breathing room air at sea level, their PaCO2 is in normal range (let's say 40mmHG, since normal is between 35-45mmHg), and their respiratory rate is 12: PAO2= .21(760-47)-(40/0.8); .21(713)-(50)= 149.73-50=99.73 So the PAO2= 99.73mmHg
Mean = (27+27+29+32+35)/5 = 150/5 = 30 Median = 29 Difference = 1
