List the 3 regulators of acid base balance in order of their action.
|
1. chemical buffer systems- keeps pH relatively constant
2. respiratory control- makes changes quickly 3. renal control- takes a while (1-2 wks, but permanent adjustment) |
|
|
what is the normal value of pH?
|
7.35-7.45
|
|
|
what is the normal value of pCO2?
|
35-45 mm Hg
|
|
|
what is the normal value of HCO3?
|
22- 26 mEq/L
|
|
|
____ reflects the respiratory component of acid-base?
|
pCO2
|
|
|
____ reflects the metabolic component of acid-base?
|
HCO3 - bicarbonate
|
|
|
alkalosis is an abnormal condidtion caused by excess____ or deficiency of ____?
|
bicarbonate/acid
|
|
|
acidosis is an abnormal increase in hydrogen ion concentration as a result of an accumulation of an ____ or loss of a ____?
|
acid/ base
|
|
|
s/s of resp. acidois-
decrease in ___ and increase in _____? |
pH/ pCO 2
|
|
|
s/s of resp. alkalosis-
decrease in ___ and increase in _____? |
pCO2 / pH
|
|
|
what are some ways you could lose bicarbonate?
|
diarrhea, draining wounds, renal failure, DKA, ASA OD, starvation, shock
|
|
|
what are some interventions for metabolic acidosis
|
sodium bicarbonate (temp fix), dialysis
|
|
|
what are some treatments for metabolic alkalosis?
|
Diamox- which will increase the excreation of bicarbonate from the kidney
|
|
|
pick increase or decease,
an acidotic state is considered to make pH?, CO2?, HCO3? |
pH- decrease
CO2- increase HCO3- decrease |
|
|
pick increase or decease,
an alkalotic state is considered to make pH?, CO2?, HCO3? |
pH- increase
CO2- decrease HCO3- inecrease |
|
|
explain pH compensation
|
pH is normal but pCO2 or HCO3 are out of balance
|
|
|
lungs will compensate if the primary imbalance is _____?
|
metabolic
|
|
|
kidneys will compensate if the primary imbalance is _____?
|
respiratory
|
