Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO 2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Body mass index over 30 kg/m 2 (a measure of obesity, obtained by taking one's weight in kilograms and dividing it by one's height in meters squared) Arterial carbon dioxide level over 45 mmHg or 6.0 kPa as determined by arterial blood gas measurement
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...
Diagnoses can be done by doing an ABG (Arterial Blood Gas) laboratory study, with a pH <7.35 and a PaCO2 >45 mmHg in an acute setting. Patients with COPD and other Chronic respiratory diseases will sometimes display higher level of PaCO2 with HCO3- >30 and normal pH. [citation needed] [2]

Monitoring the level of carbon dioxide in neonatal infants to ensure that the level is not too high (hypercarbia) or too low is important for improving outcomes for neonates in intensive care. [4] Carbon dioxide can be monitored by taking a blood sample ( arterial blood gas ), through the breath ( exhalation ), and it can be measured ...
