Hypercapnia is generally defined as an arterial blood carbon dioxide level over 45 mmHg (6 kPa). Since carbon dioxide is in equilibrium with carbonic acid in the blood, hypercapnia drives serum pH down, resulting in respiratory acidosis.
Hiperkapnija (lat. hypercapnia) je stanje povišenog parcijalnog pritiska ugljen-dioksida (PaCo2) u arterijskoj krvi i ostalim telesnim tečnostima, praćeno viškom ugljen-dioksida u telesnim tečnostima.
Exclusively caused by alveolar hypoventilation. Results from decrease in respiratory rate, tidal volume, or increase in dead space.
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 either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic.
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.
Hypercapnia is when there is too much carbon dioxide (CO2) in the blood. This is normally caused by hypoventilation of the body which leads to CO2 retention. Hypercapnia is the elevation in the partial pressure of carbon dioxide (PaCO2) above 45 mm Hg on Arterial Blood Gas readings. [1]
