If the lungs and kidneys are unable to remove large amounts of carbon dioxide from the body, respiratory failure and damage to vital organs may result. Hypercapnia, also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide levels in the blood. High carbon dioxide (bicarbonate) levels may be triggered by: Vomiting, dehydration, blood transfusions, or overuse of medications which contain bicarbonate (especially antacids).   When mild, this can often be corrected with supplemental oxygen therapy and other COPD medications, however, it can be caused by improperly-dosed oxygen therapy, as well. You breathe out carbon dioxide and breathe in oxygen all day, every day, without thinking about it. The level carbon dioxide in the liquid part of the blood -serum- is controlled by the lungs and kidneys. It is a waste product made by your body. The result is low blood oxygen levels (hypoxemia) and high blood carbon dioxide levels (hypercapnea) that make it more and more difficult to breathe. It is advised by the doctor based on your symptoms. High CO2 levels in the blood mean that the body may be experiencing respiratory or metabolic acidosis, conditions in which the blood’s pH level is excessively acidic. A high carbon dioxide level (hypercapnia) is generally defined as a CO2 pressure of 45 mmHg and 75 mmHg is considered to be severe hypercapnia. High levels of CO2 develop in the blood if the lungs or kidneys are unable remove … The amount of CO2 in your blood is carefully regulated. The normal value of carbon dioxide level in adults are 22 to 29 mmol/L. High and low levels of carbon dioxide in the blood may be due to various medical conditions. Therefore, too much carbon dioxide level in blood will cause respiratory acidosis. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs. A carbon dioxide blood test is a part of the electrolyte panel test. Inability of the lungs to clear carbon dioxide leads to respiratory … Carbon dioxide (CO2) is an odorless, colorless gas. What Is Carbon Dioxide Blood Test? Too much or too little carbon dioxide in the blood can indicate a health problem. Carbon dioxide may accumulate in any condition that causes hypoventilation, a reduction of alveolar ventilation. Carbon dioxide (CO2) normally comprises about 385 parts per million (ppm) in the atmosphere. A value of 33mmol/l in a patient will indicate hypercapnia. Conditions such as anorexia, chronic obstructive pulmonary disease (COPD), fluid in the lungs (pulmonary edema), heart disease, Cushing’s disease, or Conn’s syndrome. The partial pressure of CO2 in the blood is normally about 40mm of mercury (mmHg). These receptors send messages to your lungs to make you breathe more deeply and/or at a faster rate until your CO2 reaches a normal level. When CO2 levels become elevated, special receptors in your brain detect the increased blood level. Know how to lower high carbon dioxide levels in blood and their causes Your blood carries carbon dioxide to your lungs. The symptoms of abnormal carbon dioxide levels are weakness, fatigue, and vomiting. A CO2 blood test measures the amount of carbon dioxide in your blood.
