Lab #6 Acid base Flashcards
What is blood acidosis
pH of body fluids below 7.35
What is blood alkalosis
pH of blood above 7.45
What could cause respiratory acidosis
inadequate ventilation reducing the elimination of CO2
What could cause respiratory alkalosis
Hyperventilation or high altitude
What are the three major buffer systems of the body
Carbonic acid bicarbonate
Protein buffer
Phosphate buffer
What does the carbonic acid buffer system buffer
it is responsible for buffering the ECF
What does protein buffer system buffer
it buffers both the ICF and ECF
What does the phosphate buffers system buffer
major buffer system of the ICF but also buffers the urine
What is the proton acceptor in the CBBS
Sodium Bicarbonate NaHCO3
What is the proton donor in the CBBS
H2CO3 Carbonic acid
What is buffering range
The pH range in which the buffer system is effective
What is the CBBS chemical equation
H2CO3 <——> H + HCO3
What are the two colors of phenolphthalein and in what pH do they occur
it is bright pink in basic solutions and colorless in acidic solutions
