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.
What It Feels Like
A sudden drop in your blood CO 2 level due to hyperventilation typically causes an array of symptoms, including lightheadedness, tingling in your arms and legs and around your mouth, foggy thinking, and possibly fainting.

What is CO2 in blood?
The CO2 blood test measures the amount of carbon dioxide in the blood, which is present in the form of CO2, bicarbonate (HCO3), and carbonic acid (H2CO3). It mainly occurs in the form of bicarbonate.
What does it mean when bicarbonate levels are high?
High or low bicarbonate levels can indicate that a person has metabolic alkalosis or acidosis, respectively. Both arterial and venous blood draws can provide an overall picture of a person’s electrolyte status and the balance of acids and bases in their blood.
Why is CO2 considered an acidic component?
Carbon dioxide is an “acidic” component because it combines with water to form carbonic acid. This makes the blood acidic. The CO2 blood test detects changes in the blood’s acidic content. A healthcare professional can measure the levels of CO2 in a person’s blood using a simple blood test.
What does it mean when your CO2 is high?
A higher-than-normal CO2 level can indicate a breathing disorder. An abnormal CO2 test result could mean that there are either high or low CO2 levels in the body. Changes in CO2 levels may suggest that someone is losing or retaining normal body fluids. This points to an imbalance in the body’s electrolyte system.
What organs maintain CO2 levels?
The kidneys and lungs maintain the concentration of CO2 in the blood. If a person’s blood CO2 levels are above the normal range, a doctor may request further tests to check kidney and lung function, to assess other gases in the blood, or to check for fluid retention.

What is low CO2?
Definition of Low CO2 (hypocapnia) Hypocapnia (hypocapnea, also known as hypocarbia) is defined as a deficiency of carbon dioxide in the arterial blood. This is a major respiratory symptom. Most medical sources define hypocapnia as less than 35 mm Hg for partial CO2 pressure in the arterial blood.
What is the effect of alveolar hypocapnia?
The key pathological effect of both, alveolar and arterial hypocapnia is reduced levels of oxygen in body cells (tissue hypoxia), This promotes virtually all chronic diseases. These and other physiological effects associated with low CO2 and low oxygen levels in body cells, with numerous medical studies, are provided below (in CO2-related links).
Is alveolar hypocapnia common?
These studies (see the Table below) show that alveolar hypocapnia is very common for many chronic diseases. Most of these patients (with heart disease, diabetes, cancer, and so forth) have arterial hypocarbia as well. Furthermore, this Table also identifies the cause of hypocapnia.
What is CO2 in blood test?
CO2 blood test. CO2 is carbon dioxide. This article discusses the laboratory test to measure the amount of carbon dioxide in the liquid part of your blood, called the serum. In the body, most of the CO2 is in the form of a substance called bicarbonate (HCO3-). Therefore, the CO2 blood test is really a measure of your blood bicarbonate level.
Why is CO2 tested?
The CO2 test is most often done as part of an electrolyte or basic metabolic panel. Changes in your CO2 level may suggest that you are losing or retaining fluid. This may cause an imbalance in your body's electrolytes. CO2 levels in the blood are affected by kidney and lung function.

Why does the pH of the blood change?
A pH imbalance in the blood can be caused primarily by a respiratory issue (the lungs are not effectively balancing the intake of oxygen and the release of carbon dioxide) or a metabolic issue (increased or decreased bicarbonate in the blood). Additionally, the balance of bicarbonate and other electrolytes in the body is a good indicator ...
