Metabolic disorder
change in what
-change in the bicarb concentration
Respiratory disorder-
change in what
change in the CO2
Metabolic acidosis-
ph
bicarb
pH < 7.35
bicarb less than 22 mEq/L
Metabolic alkalosis-
ph
bicarb
bicarb- pH > 7.45
bicarb > 26 mEq/L
Respiratory acidosis-
ph
paco2
pH < 7.35
PaCO2 > 45 mmHg
Respiratory alkalosis-
ph
paco2
pH> 7.45
PaCO2 < 35 mmHg

primary imbalance
acid base imbalance
caused by one source
either resp or met
mixed imbalance
acid base imbalance
caused by both met and rest
Compensation-
how the body attempts to return homeostasis. It wants to balance the pH.
Primary imbalance
source of the problem
it is what is causing the imbalance
compensation how fast
respiration
renal
resp can happen quickly
renal takes longer
compensated
ph where
PaCO2 / HCO3 where
If pH is NORMAL,
PaCO2 and HCO3 are both ABNORMAL
Partially Compensated
ph where
PaCO2/ HCO3 where
If pH is ABNORMAL,
PaCO2 and HCO3 are both ABNORMAL
Uncompensated
ph where
PaCO2/ HCO3 where
If pH is ABNORMAL
PaCO2 OR HCO3 is ABNORMAL =
ABG Interpretation
1- ph
2 pco2/hco3
3if both
4look at/is pt
Is the pH normal, acidotic or alkalotic?
Is the pCO2 or HCO3 abnormal?
If they are both abnormal, which one deviates the most from the norm and is causing the change in pH?
Look at the Po2, is the pt hypoxic?
RO
when ph is up
when ph is down
ROME
Respiratory Opposite
When pH is up, PaCO2 is down = Alkalosis
When pH is down, PaCO2 is up = Acidosis
ME
when ph is up
when ph is down
ROME
Metabolic Equal
When pH is up, HCO3 is up = Alkalosis
When pH is down, HCO3 is down = Acidosis
acids to what to hydrogen
bases do what to hydrogen
Acids- release hydrogen in solution
Base- accepts hydrogen in solution
low ph=what=how much hydrogen //levels
high ph=what=how much hydrogen //levels
Low pH = acidic-more hydrogen-<7.35
High pH = alkaline-less hydrogen >7.45
Volital acids
how eliminated
can be elimated as a gas
such as carbonic acid from lungs
Non volital acids
how excreted
must be excreted as body fluids like lactic acid
