Potential Health Risks Of Low Co2 Levels
As discussed so far, low CO2 levels may indicate problems with acid-base balance in the blood, which may require urgent medical attention. In the section below, well discuss the health risks of chronically low CO2 levels, according to research.
However, low CO2 levels do not always indicate that there is a problem. Always talk with your doctor to learn more about your test results.
Causes Of Low Carbon Dioxide Levels
A number of factors can affect carbon dioxide levels. If your results are outside of the normal range, it may not necessarily mean there is something wrong. However, a normal result also doesnt mean a particular medical condition is absent. Always talk with your doctor to learn more about your test results.
Most of the carbon dioxide in the body is created as a byproduct by cells when they convert sugars and fats into energy. This provides a steady source of CO2, which then leaves the body whenever a person breathes out .
Its very rare for the human metabolism to produce less CO2. Instead, the main reason for low CO2 levels is due to more CO2 leaving the body, usually through increased exhalation .
Several different factors can increase the amount of CO2 that leaves the body. In the following sections, well list out some major reasons for low CO2 levels and the effect that has on ones health.
How The Test Works
A doctor or nurse will take a sample of your blood from your arm with a needle. Let your doctor know if you take any medications or supplements, because they can affect the results. So can eating grapefruits, tangerines, and other fruits high in acid.
The test uses only the fluid in your blood, not the blood cells or the platelets that help your blood clot. A lab technician will add acid to the liquid to unlock carbon dioxide from the bicarbonate. The amount of bicarbonate is measured by how fast the sampleâs acidity changes.

The most common use of PCO2 is the monitoring of respiratory and acid-base status in patients while receiving mechanical ventilation. Respiratory care practitioners carry out the measurements of PCO2 and the adjustments to ventilation on the machine itself. While there are many protocols in ventilator management, they do share a commonality in that the respiratory care practitioner, nursing, and the other members of the medical team should analyze the patient’s overall ventilation and acid-base status as a collective group.
When Would I Have The Test
Itâs usually part of a larger electrolyte test that tells your doctor how much sodium, potassium, and chloride is in your body. They may do this test as part of a regular checkup, or to try to find out why you donât feel well.
Your doctor might check the CO2 levels in your blood if you have:
- Vomiting or diarrhea that wonât go away
- Trouble breathing
- Weakness or tiredness
If youâre being treated for liver, lung, or digestive conditions, your doctor might check your bicarbonate levels regularly to see if your therapy or medication is working.

How Is Carbon Dioxide Transported In The Blood
Most of the carbon dioxide in your body is in the form of bicarbonate, which is a type of electrolyte.
The pH of the human body ranges between 7.35 to 7.45, with the average at 7.40 1). The primary pH buffer system in the human body is the bicarbonate /carbon dioxide chemical equilibrium system 2). Where:
H + HCO3- < > H2CO3 < > CO2 + H2O
Bicarbonate functions as an alkalotic substance. CO2 functions as an acidic substance. Therefore, increases in bicarbonate or decreases in CO2 will make blood more alkalotic. The opposite is also true where decreases in HCO3 or an increase in CO2 will make blood more acidic. CO2 levels are physiologically regulated by the pulmonary system through respiration, whereas the HCO3 levels are regulated through the renal system with reabsorption rates. Therefore, metabolic alkalosis is an increase in serum HCO3.
How To Lower High Co2 Levels In Blood
People with high CO2 levels are usually indicative of metabolic alkalosis. The treatment varies depending on the kind of alkalosis suffered. If it is chloride-responsive, then a change in lifestyle might suffice, such as increasing the consumption of salt or sodium chloride. Other healthcare providers may give you a saline solution or an IV. If it is chloride-resistant, then you may be required to increase your potassium levels, such as by receiving potassium chloride and taking pills with potassium chloride.
If your result does not indicate normal CO2 levels, maybe due to acidosis or alkalosis, your doctor will determine the cause of the abnormalities and suggest the appropriate treatment for your condition. You can maintain normal CO2 levels in blood upon the proper treatment, including medications, lifestyle changes, and surgery.

How The Co2 Blood Test Is Performed
A blood sample is needed. Most of the time blood is drawn from a vein located on the inside of the elbow or the back of your hand. A health care professional will take a blood sample from a vein in your arm, using a small needle.
How to prepare for the CO2 blood test
Many medicines can interfere with blood test results.
- Your health care provider will tell you if you need to stop taking any medicines before you have this test.
- DO NOT stop or change your medicines without talking to your provider first.
- Drugs that may decrease bicarbonate levels include methicillin, nitrofurantoin, tetracycline, thiazide diuretics, and triamterene.
- Some drugs may increase bicarbonate levels including fludrocortisone, barbiturates, bicarbonates, hydrocortisone, loop diuretics, and steroids.
What Is A Blood Test
A blood test is when a sample of blood is taken from the body to be tested in a lab. Doctors order blood tests to check things such as the levels of glucose, hemoglobin, or white blood cells. This can help them detect problems like a disease or medical condition. Sometimes, blood tests can help them see how well an organ is working.

What Do The Results Mean
Abnormal test results may be a sign that your body is having a hard time keeping the right acid-base balance . This may be because your lungs or kidneys are having a problem removing carbon dioxide or because you have an electrolyte imbalance. Many different types of conditions can cause these problems.
Too much CO2 in the blood can be a sign of many conditions, including:
- Metabolic acidosis, a condition in which your blood is too acidic. It may be caused by many things, including kidney or liver disease, or long-lasting diarrhea.
- Respiratory alkalosis, a condition in which your blood is not acidic enough because of lung or breathing disorders, including hyperventilation .
If your test results are not in the normal range, it doesn’t necessarily mean you have a medical condition that needs treatment. Other factors, including certain medicines, can affect the level of CO2 in your blood. To learn what your results mean, talk with your provider.

What Do Low Co2 Levels In Blood Indicate
Blood functions significantly to perform all the metabolic processes very well. And all this happens only when the pH of blood is in the range of 7.35-7.45. Any kind of raise and fall in this range of pH results in acidosis and alkalosis, which also causes high and low CO2 levels in blood. And ultimately, other systems of the body stop working properly.
Hence, it is important to maintain blood pH levels to maintain acid-base balance in the body. The acid-base balance is controlled by the kidney and lungs. So, any imbalance in acids and base means kidney and lung function is get affected.
These are directly associated with the carbon dioxide levels in the blood. High and low CO2 levels in blood are responsible for various diseases including lung and kidney disease. It is going to be essential to know about low CO2 levels in the blood. As it is associated with life-threatening health conditions.
Here, everything about the low CO2 levels in blood is going to be covered. Including what are the signs and causes of low carbon dioxide and also the ways to raise the CO2 level in the blood. So scroll down to the end and grab this information.

When Is It Ordered
Bicarbonate testing may be ordered when you have a routine health checkup.
This testing may also be ordered when acidosis or alkalosis is suspected or when you have an acute condition with symptoms such as:
- Prolonged vomiting and/or diarrhea
- Weakness, fatigue
- Difficulty breathing
Electrolytes may be ordered at regular intervals when you have a disease or condition or are taking a medication that can cause an electrolyte imbalance.
What Does Low Carbon Dioxide In Blood Indicate
Can anxiety cause low CO2 levels in blood?Often one of the first symptoms of a panic attack is hyperventilating , which upsets the natural balance of oxygen and carbon dioxide in our system. One view says a low level of carbon dioxide in the blood directly triggers the symptoms of panic, such as feeling lightheaded and dizzy.
Can dehydration cause low CO2 levels?
A low level may be caused by: Hyperventilation. Aspirin or alcohol overdose. Diarrhea, dehydration, or severe malnutrition.
How do you increase carbon dioxide in your body?
Breathing control via your nose during training. This encourages the body to offload the carbon dioxide and increase the amount of CO2 in the body. The more you do it, you will find that your pace will increase.
What causes low CO2 levels in blood test?
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.

How Is A Cmp Done
Most blood tests take a small amount of blood from a vein. To do that, a health professional will:
- put an elastic band above the area to get the veins to swell with blood
- insert a needle into a vein
- pull the blood sample into a vial or syringe
- take off the elastic band and remove the needle from the vein
In babies, blood draws are sometimes done as a “heel stick collection.” After cleaning the area, the health professional will prick your baby’s heel with a tiny needle to collect a small sample of blood.
Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.

Maintaining Carbon Dioxide Levels
If your CO2 levels are too low, the first step your doctor will take is treating the underlying condition that is causing the imbalance. This could mean anything from treating possible kidney or lung issues to stopping certain medications .
There are some general recommendations that may help prevent conditions that cause imbalances in CO2 levels, which are listed below. Talk to your doctor to learn best how to manage your condition.
- Drink plenty of water, dehydration is a common cause of metabolic acidosis
- Limit alcohol consumption, drinking too much can lead to metabolic acidosis
- Keep diabetes well controlled
- Breathing exercises and relaxation techniques may help with hyperventilation for those with anxiety

What Is The Co2 Blood Test
A CO2 blood test measures your level of bicarbonate, an indicator of how much CO2 is in your blood. CO2 is a form of natural waste that your body produces. Your blood carries CO2 to your lungs, where you breathe it out. Too little or too much CO2 in your blood may be a sign of a more serious health problem.
Low Co2 Levels In Blood Or Hyperventilation
Low carbon dioxide levels in the blood mean your body removes CO2 in excess that its deficiency occurs inside the body. Sometimes this kind of condition happens for short period but if it remains so long then it is not good. It might be a sign of any health problem including lung diseases and breathing disorders.

Your child may be asked to stop eating and drinking for 8 to 12 hours before a CMP. Tell your doctor about any medicines your child takes because some drugs might affect the test results.
Wearing a T-shirt or short-sleeved shirt for the test can make things easier for your child, and you also can bring along a toy or book as a distraction.
How Do You Treat Low Co2 Levels
Usually, a person who has low levels of CO2 may be suffering from metabolic acidosis. There are various types of metabolic acidosis and have their own treatments. Acidosis due to kidney failure can be treated with sodium citrate. If it is due to hyperchloremic acidosis, a person may be given oral sodium bicarbonate.
If a person is diabetic, he may have IV fluids and insulin at the same time. Depending on the cause of lactic acidosis, a person may be given IV fluids, bicarbonate supplements, antibiotics, or oxygen.

What Is This Test
This test measures how much carbon dioxide is in your blood.
When you digest food, your body makes carbon dioxide as a waste product in the form of gas. Your blood carries this gas to your lungs. You exhale it and breathe in oxygen thousands of times a day. Carbon dioxide in your blood usually causes no problems. But if you have far too much or too little of it, you may have a disease or a health emergency.
Most of the carbon dioxide in your body is in the form of bicarbonate. This is made by your kidneys. Bicarbonate is used to keep the acids and bases in your blood in balance.
The test measures all types of carbon dioxide in your blood: bicarbonate, carbonic acid, and dissolved CO2. Because of this, it gives only an estimate of the amount of bicarbonate.
How Do I Prepare For A Co2 Blood Test
Before the blood draw, ask your healthcare provider if you should stop taking any medications, vitamins or supplements. Sometimes, certain medications can affect the results of a blood test. Always ask your provider before stopping any medication.
You dont need to stop eating or drinking before a CO2 blood test. But you may be having other blood tests in combination with a CO2 blood test that may require fasting. Ask your healthcare provider in advance if you should fast before the test.

What Is The Test Used For
A CO2 blood test is often ordered as part of an electrolyte panel, a collection of tests often ordered as part of a regular checkup. Electrolytes help to keep your body’s acid and base levels in check. Bicarbonate, a type of electrolyte, contains most of the carbon dioxide in your body. The test can also be used to monitor or diagnose electrolyte-related disorders such as kidney diseases, lung disorders, and high blood pressure.
What Are The Symptoms Of Low Carbon Dioxide
Too little CO2 in the blood may indicate: Addison’s disease, another disorder of the adrenal glands. In Addison’s disease, the glands don’t produce enough of certain types of hormones, including cortisol. The condition can cause a variety of symptoms, including weakness, dizziness, weight loss, and dehydration.

Causes Of Low Carbon Dioxide In The Blood
The trillions of cells that make up your body metabolize food molecules to generate energy. This metabolism yields carbon dioxide as a byproduct. Your body rids itself of excess CO2 via your lungs when you exhale. A small amount, however, remains in your blood and plays an important role in maintaining the acid-base balance of your bloodstream. A low blood CO2 level occurs with several conditions, some relatively harmless and others more serious.

Connections To Anxiety And Panic Disorder
Hyperventilation often goes hand in hand with anxiety and panic attacks. There is evidence that CO2 levels in the blood also may play an important role .
For example, research suggests that baseline CO2 levels in people with panic disorder and PTSD are lower compared to the general population. Some researchers theorize that this lower baseline CO2 level is a natural coping mechanism of the body since sudden increases in CO2 are known to trigger panic attacks .
What Is The Purpose Of A Co2 Blood Test
A CO2 blood test is often done as part of an electrolyte panel . Your healthcare provider may order a CO2 blood test if you have symptoms including:
- Trouble breathing.
Testing carbon dioxide levels in the blood helps healthcare providers see if your body is balancing electrolytes properly. Certain health conditions can cause electrolyte imbalances, including high blood pressure, kidney diseases and lung diseases.
