Introduction[edit | edit source]
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 defined when the PaCO2 is greater than 4.2kPa on an arterial blood gas (ABG).[1]
Hypercapnia can be caused by long term hypoxaemia which causes the body to compensate leading to increased CO2 in the blood. This is known as type 2 respiratory failure and is defined as when PaCO2 is greater than 4.2kPa and PaO2 is less than 8kPa.[1] (these ranges can differ slightly depending on the book or article).[2]
