Hypoventilation

hypoventilation /hy·po·ven·ti·la·tion/ (-ven?ti-la´shun) reduction in amount of air entering pulmonary alveoli.

---

primary alveolar hypoventilation  impairment of automatic control of respiration, resulting in apnea during sleep.

hy·po·ven·ti·la·tion (hp-vntl-shn)

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.

---

Hypoventilation

Reduced ventilation in the lungs' air sacs resulting in above normal carbon dioxide pressure.

hypoventilation (hīˈ·pō·vēnˈ·t·lāˑ·shn),

n breathing dysfunction characterized by insufficient respiration, resulting in inadequate oxygenation and build-up of excess carbon dioxide in the body.

---

hypoventilation,

n an abnormal condition of the respiratory system, characterized by cyanosis, polycythemia, increased carbon dioxide arterial tension, and generalized decreased respiratory function. Hypoventilation occurs when the volume of air that enters the alveoli and takes part in gas exchanges is not adequate for the metabolic needs of the body.
