Normal pH is this. What direction is pH when acidosis and then alkalosis
|
7.35 to 7.45
alkalosis - > 7.45 acidosis - < 7.35 I |
|
|
If pH is < 7.35 how do you determine primary abnormality?
|
Look at PCO2 and Bicarb. PCO2 > 45 would indicate pulmonary acidosis, a Bicarb < 22 would indicate metabolic acidosis
|
|
|
If pH is > 7.45 how do you determine primary abnormality?
|
Look at PCO2 and Bicarb. If PCO2 < 35 would indicate repiratory alkalosis, Bicarb > 26 would indicate metabolic alkalosis
|
|
|
Normal PCO2
|
35 to 45 (higher number is acidosis)
|
|
|
Normal Bicarbonate (CO2)
|
22 to 26
|
|
|
RULE 2 for evaluating Acid / Base disorders and how do you perform this.
|
Calculate an ANION gap. IF present (>12) this indicates a PRIMARY metabolic acidosis regardless of pH or bicarb concentration
sodium - bicarb + chloride. (normal is 12) |
|
|
WHat is the excess anion gap and how is this calculated
|
Excess anion gap = Total anion gap - normal anion gap (12). This result is added to measured BICARB.
IF > 30 metabolic alkalosis is presnet, if < 23 metabolic acidosis is present. |
