My comment was that the Henderson/Hasselbach equation is basically an equation to confuse the medical community even MORE! (I had heard this even before Professor Ed mentioned it. But the reasoning is:

1) In acidosis you would think that as H+ increases pH increases and in alkalosis you would think that as H+ decreases pH decreases.

2)But No, No in acidosis pH decreases and in alkalosis pH increases

3)*The log is an inverted concept and makes you think in reverse!!

4)This is the CONFUSION: pH=6.1+log [HCO3-]/0.03 times pCO2

5)The stronger concept is to =[HCO3-]/pCO2 with arrows going in the same direction to indicate compensation.

Hope this is clear, and I rest my case :shock:
