Questions & Step-by-Step Solutions

What is the effect of hyperventilation on blood pH?
  • Step 1: Understand what hyperventilation is. It means breathing very fast and deeply.
  • Step 2: Know that when we breathe, we take in oxygen and breathe out carbon dioxide (CO2).
  • Step 3: During hyperventilation, we breathe out too much CO2.
  • Step 4: When CO2 levels in the blood decrease, it affects the balance of acids and bases.
  • Step 5: The decrease in CO2 leads to an increase in blood pH, making the blood more alkaline.
  • Step 6: This condition is called respiratory alkalosis, which means the blood is less acidic than normal.
