Verified step by step guidance
1
Understand that pH is a measure of the acidity or alkalinity of a solution, with lower pH values indicating higher acidity.
Recognize that hypoventilation refers to decreased ventilation, leading to an accumulation of carbon dioxide (CO2) in the blood.
Recall that CO2 reacts with water in the body to form carbonic acid (H2CO3), which dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-).
Realize that an increase in hydrogen ions (H+) due to the accumulation of carbonic acid will lower the pH, making the blood more acidic.
Conclude that hypoventilation causes a drop in pH because it leads to respiratory acidosis, a condition where CO2 buildup results in increased acidity in the blood.
