hypercapnia

A higher than normal level of carbon dioxide in the blood. This suggests that ventilation in the air sacs of the lungs (alveoli) is inadequate possibly because the sensitivity of the respiratory centre to raised CO2 levels has been affected. In health, hypercapnia always causes an increased rate and depth of breathing.

hypercapnia

The presence of a raised carbon dioxide content or tension in a milieu (e.g. blood, tears). Contact lens wear tends to give rise to this condition, especially lenses of low gas transmissibility. See acidosis.
