hypoventilation

 [hi″po-ven″tĭ-la´shun]
a state in which there is a reduced amount of air entering the pulmonary alveoli (decreased alveolar ventilation), which causes an increase in arterial carbon dioxide level. See also hypopnea and bradypnea.

hy·po·ven·ti·la·tion

(hī'pō-ven'ti-lā'shŭn),
Reduced alveolar ventilation relative to metabolic carbon dioxide production, so that alveolar carbon dioxide pressure increases above normal.

n.
Reduced or deficient ventilation of the lungs, resulting in reduced aeration of blood in the lungs and an increased level of carbon dioxide in the blood.
