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.
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 ...
Carbon dioxide is a by-product of food metabolism and in high amounts has toxic effects including: dyspnea, acidosis and altered consciousness. [8] Arterial blood carbon dioxide tension. P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 mmHg and 45 mmHg. [9] Venous blood carbon dioxide tension
Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO 2) in the respiratory gases.Its main development has been as a monitoring tool for use during anesthesia and intensive care.
In chronic respiratory acidosis, the PaCO 2 is elevated above the upper limit of the reference range, with a normal blood pH (7.35 to 7.45) or near-normal pH secondary to renal compensation and an elevated serum bicarbonate (HCO 3 − >30 mEq/L). [citation needed]
In 1854, Adrien Chenot similarly suggested carbon monoxide to remove the oxygen from blood and then be oxidized by the body to carbon dioxide. [54] The mechanism for carbon monoxide poisoning is widely credited to Claude Bernard whose memoirs beginning in 1846 and published in 1857 phrased, "prevents arterials blood from becoming venous".
2") is a blood test that usually appears on a "Chem 19" or an electrolyte panel. The value measures the total dissolved Carbon dioxide (CO 2) in blood. It is determined by combining the Bicarbonate (HCO − 3) and the partial pressure of CO 2 multiplied by a factor which estimates the amount of pure CO
