Question

c. Why does pH change as a result of hyperventilation?

( note: i want short answer )

Electro EEG II: This lab will record an EEG from a subject that is relaxed with eyes closed performing mental arithmetic, hyperventilating and relaxed with eyes open. Students will then examine the alpha rhythm activity during these conditions. B. EEG Amplitudes: complete with the amplitudes of the recorded data.

Explanation / Answer

Why does pH change as a result of hyperventilation?

Answer:

One of the most common causes of hyperventilation is respiratory alkalosis. When the body receives more oxygen than it needs, as a result, the amount of carbon dioxide found in the blood drops to a level below the normal range. The decreased partial pressure of arterial carbon dioxide (PaCO2 increases the ratio of bicarbonate concentration to PaCO2 and, thereby, increases the pH level it results in respiratory alkalosis (high pH).
