Term
| how does acidosis affect kidney function (reabsorption/secretion) |
|
Definition
| kidney substitutes secretion of K+ for H+, so K+ is retained in cell and hyperkalemia results |
|
|
Term
| major source of H+ in body? |
|
Definition
| carbonic acid production from CO2 and H20 |
|

Term
| Henderson Hasselbach equation? |
|
Definition
| ph = pka + log (unprotonated)/(protonated) |
|
|
Term
| high levels of H+ does what to ventilation? |
|
Definition
| increases to decrease CO2 levels |
|
|
Term
| low levels of H+ does what to ventilation? |
|
Definition
| lowers it (depresses) to increase amounts of CO2 and therefore H+ |
|

Term
| cause of respiratory acidosis? |
|
Definition
| retnention of CO2--hypoventilation |
|
|
Term
| how do u compensate for respiratory acidosis? |
|
Definition
| retain HCO3- to balance out the elevated CO2 |
|
|
Term
| causes of metabolic acidosis |
|
Definition
diarrhea (loss of HCO3-)
diabetes, xs fat metab, ketoacidosis, exercise (lactic acid), uremic acidosis-renal failure |
|
|
Term
| how do u compensate for metab acidosis? |
|
Definition
| increase pulmonary function, hyperventilate, excrete acid, connserve more HCO3- |
|
|
Term
| causes of respiratory alkalosis: |
|
Definition
loss of CO2 (hyperventilation)
fever
anxiety
aspirin poisoning, high alts |

|
Term
| compensation for metab alk? |
|
Definition
hypoventilation (conserve CO2)
secrete less H+ and excrete more HCO3- |
