a Metabolic acidosis,
b Metabolic acidosis+respiratory acidosis
Any one knows the formula?
Many thanks | g*****y
发帖数: 4 | 2 a - metabolic acidosis b/c PH<7.35, HCO3<22,PCO2 normal (33-45). | s******n
发帖数: 65 | 3 is it possible respiratory acidosis because PH is so low | s*******r
发帖数: 174 | 4 First u got it is met acidosis because hco is 17, then u calculate
compensation by winter fomular co2 should be 33
with adequate compensation. Ur real co2 is 38, so u got the conclusion that
there is also res acidosis.

发帖数: 65 | 5 Correct answere is b. could you explain more detail, like which formula you
used.
Thanks | l*****n
发帖数: 81 | 6 when you decide it's metabolic acidosis, the right next step is use winter
formula as Soaplover said to see whether there is superimposed respiratory
component
1.5x HCO3 +8 = calculated compensatory CO2
Compare the real CO2 to compensatory CO2, if significantly greater, then
metabolic acidosis plus respiratory acidosis, if less, then metabolic
acidosis plus respiratory alkalosis | b****o
发帖数: 169 | 7 那有没有对应的公式决定是否combined metabolic alkalosis and respiratory alkalosis?
