Carbon dioxide (CO2) is an odorless, colorless gas. It is a waste product made by your body. Your blood carries carbon dioxide to your lungs. You breathe out carbon dioxide and breathe in oxygen all day, every day, without thinking about it. A CO2 blood test measures the amount of carbon dioxide in your blood.30-Jul-2020
- 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. As part of its normal functions, the human body naturally produces certain acids and bases that balance each other.
What is a normal CO2 level?
Test results. The normal range for CO2 is 23 to 29 mEq/L (milliequivalent units per liter of blood). The blood test often measures blood pH along with CO2 levels to further determine the cause of your symptoms. Blood pH is a measurement of acidity or alkalinity.
What does a low CO2 level mean?
A low CO2 level can be a sign of several conditions, including: Kidney disease. Diabetic ketoacidosis, which happens when your body’s blood acid level goes up because it doesn’t have enough insulin to digest sugars. Metabolic acidosis, which means your body makes too much acid.
What are symptoms of high CO2 levels?
Mild symptoms of hypercapnia include: flushed skin. drowsiness or inability to focus. mild headaches. feeling disoriented or dizzy. feeling short of breath. being abnormally tired or exhausted.
What causes CO2 levels to rise?
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
What does a CO2 level of 34 mean?
For example, it may be 20 to 29 milliequivalents per liter (mEq/L) of blood, 22 to 34 mEq/L, etc. Higher than normal carbon dioxide levels may reflect excessive loss of acid (as with recurrent vomiting or continuous gastric drainage) or acid-base disorders (such as primary aldosteronism and Cushing syndrome).
What happens if carbon dioxide levels in the blood are too high?
Hypercapnia is excess carbon dioxide ( CO2 ) build-up in your body. The condition, also described as hypercapnea, hypercarbia, or carbon dioxide retention, can cause effects such as headaches, dizziness, and fatigue, as well as serious complications such as seizures or loss of consciousness.
Can anxiety cause low CO2 levels in blood?
But when you hyperventilate, the carbon dioxide levels in your bloodstream drop too low. You’ll notice it right away because you’ll start to feel sick. Hyperventilation happens most often to people 15 to 55 years old. It can come about when you feel nervous, anxious, or stressed.
What does a CO2 level of 21 mean?
Normal values in adults are 22 to 29 mmol/L or 22 to 29 mEq/L. Higher levels of carbon dioxide may mean you have: Metabolic alkalosis, or too much bicarbonate in your blood. Cushing disease. Hyperaldosteronism, an adrenal gland problem.
How do you get your CO2 levels down?
Increase Ventilation Installing and maintaining a good ventilation system will help reduce CO2 levels. As the system brings in fresh outdoor air, the CO2 will naturally dilute and become less concentrated, keeping the indoor carbon dioxide within safe levels.
How do you treat high CO2 levels?
Treatments Ventilation. There are two types of ventilation used for hypercapnia: Medication. Certain medications can assist breathing, such as: Oxygen therapy. People who undergo oxygen therapy regularly use a device to deliver oxygen to the lungs. Lifestyle changes. Surgery.
How do you get rid of carbon dioxide in your body naturally?
Exercise forces the muscles to work harder, which increases the body’s breathing rate, resulting in a greater supply of oxygen to the muscles. It also improves circulation, making the body more efficient in removing the excess carbon dioxide that the body produces when exercising.
What is the treatment for hypercapnia?
If you get hypercapnia but it isn’t too severe, your doctor may treat it by asking you to wear a mask that blows air into your lungs. You might need to go the hospital to get this treatment, but your doctor may let you do it at home with the same type of device that’s used for sleep apnea, a CPAP or BiPAP machine.
How does the body compensate for an increase in CO2?
In addition, the body uses other specific mechanisms to compensate for the excess carbon dioxide. Breathing rate and breathing volume increase, the blood pressure increases, the heart rate increases, and kidney bicarbonate production ( in order to buffer the effects of blood acidosis), occur.
