Hyperventilation
Hyperventilation — breathing too rapidly or deeply than your body requires — is a leading cause of a low blood CO 2 level. When you hyperventilate, you exhale too much CO 2 causing a drop in your blood level. Hyperventilation triggered by severe pain, overwhelming fear or anxiety, or a panic attack can cause a short-term dip in your CO 2 level.
Excess Blood Acids
Excess acids in your bloodstream drive down your blood CO 2 level. This occurs with conditions that increase acid production in your body and with ingestion of certain types of medications or toxic substances. Examples include:
Excess Bicarbonate Loss
You might recall from a high school or college chemistry class that a buffer system refers to dissolved chemicals that help maintain a relatively constant pH. Bicarbonate in your body serves as potent buffer that helps keep your blood pH stable.
