******ACID BASE BALANCE DISORDER******
# # BCQS SOLVING TIPS # #
# # # # # Normal values # # # # # #
pH ... 7.35-7.45
pCO2... 35-45 mmHg (40 )
HCO3- ... 22-26 mEq/L (24 )
BUT
for solving BCQS REMEMBER
1.....pH 7.4
2.....pCO2 .. 40 mmHg
( high level means more than 40 mmHg and low level means less than 40 mmHg)
3.....HCO3- ... 24 mEq/L
( high level means more than 24 mEq/L and low level means less than 24 mEq/L)
1»»»» FIRST TIP
Look at pH first
if low then it is acidosis, if high then it is alkalosis.
2»»»» SECOND TIP
Decide either it is respiratory or metabolic.
A »»» If primary disturbance in pCO2 level..
Then it is respiratory...
Eg
if pCO2 is raised it is respiratory acidosis and if pCO2 is low it is respiratory alkalosis..
HCO3 level disturbance shows metabolic prob
B»»» if primary disturbance is in HCO3 level
Then it is metabolic..
Eg.
If HCO3 level is low it is metabolic acidosis and if HCO3 level is high it is metabolic alkalosis.
3»»»» THIRD TIP
Decide either it is compensated or uncompensated.
Eg.
A»» if primary problem is in pCO2 level
BUT
HCO3 level and pH are in normal OR near to normal range,
THEN it is compensated
B»» if primary problem is in pCO2 level
BUT
HCO3 level and pH are NOT in normal OR near to normal range,
THEN it is uncompensated
4»»»» FOURTH TIP
YOU can also assess primary disturbance....
By the history of the case..
A»»» if primary problem in respiratory system, lungs or chest , it wil be respiratory acidosis / alkalosis
B»»» if primary problem in other than lungs, i.e fever,diarhea,diabetes,exercise etc , it wil be metabolic acidosis / alkalosis..
