blood gases Flashcards
what is needed for speed up the interconversion process?
enzyme carbonic anhydrase= catalyst
process of red blood cell for c02 exchange
1) CO2 diffuses into red cell
2) CO2 + H2O react by carbonic anhydrase to form bicarbonate acid
3) Dissociates to release H+ and Hc03
4) H buffers to hemoglobin=hemoglobin acid
5) HCO3- released into plasma in exchange for Cl-
6) this process happens until goes to lungs where its all reversed
The Henderson Hassalbalch equation
what is Respiratory acidosis
too much co2 that soon mix with water in blood to make carbonic acid which lowers pH= more acidic = called acidosis
what is Respiratory alkalosis
low level of c02 in blood so ph increases= alkaline so kidney makes bicarbonate ions to lower blood ph back to normal
what is Metabolic acidosis
too much acid in blood decreasing blood ph = more acidic
to fix it lungs repsond by hyperventilating which blow of c02 to have a acid-base balance and brings back ph back to normal
what is Metabolic alkalosis
too much bicarbonate= high blood ph= alkaline
to fix this,lungs slow down breathing so c02 is low in body,this helps restore the balance between acids and bases and brings ph back to normal
why is the interconversion between carbonic acid and c02 important?
regulates the balance of c02 in body and maintain ph of bodily fluids
