Blood Ph Flashcards
What is pH a measure of?
Acidity, alkalinity, and neutrality
What is the importance of blood pH?
Needs to be controlled within very narrow limits
What does a low pH indicate?
Elevated H* ion concentration (more acidic)
What does a high pH indicate?
More alkaline
What causes a low pH (acidity) in the blood?
Increase in H* ions due to CO2 and other factors
What effect does CO2 have on blood pH?
Causes an increase in H* ions, leading to respiratory acidosis
What is respiratory acidosis?
Condition caused by increased H* ions from dissolved CO2
What is metabolic acidosis?
Condition caused by lactic acid from exercise and ketoacids from metabolism
How does ventilation affect blood pH?
Helps lower acidity via exhalation of CO2
