hypocapnia

 [hi″po-kap´ne-ah]
deficiency of carbon dioxide in the blood; it results from hyperventilation and eventually leads to alkalosis. Called also hypocarbia. adj., adj hypocap´nic.

hy·po·cap·ni·a

(hī'pō-kap'nē-ă),
Abnormally decreased arterial carbon dioxide tension.
Synonym(s): hypocarbia
[hypo- + G. kapnos, smoke, vapor]

hypocapnia

/hy·po·cap·nia/ (-kap´ne-ah) deficiency of carbon dioxide in the blood.hypocap´nic

hypocapnia

[-kap′nē·ə]
an abnormally low arterial carbon dioxide level. Also called hypocarbia.

hypocapnia

Decreased CO2 or bicarbonate in blood. Hypocapnia, even when marked, is normally well tolerated; transient induction of hypocapnia can lead to life-saving physiologic changes in patients with severe intracranial hypertension or neonatal pulmonary-artery hypertension, but hypocapnia of longer duration in critically ill patients adversely affects outcomes. Prophylactic induction of hypocapnia has no clinical role.

hypocapnia

↓ Arterial CO2

hy·po·cap·ni·a

(hī'pō-kap'nē-ă)
Abnormally decreased arterial carbon dioxide tension.
Synonym(s): hypocarbia.
[hypo- + G. kapnos, smoke, vapor]

hypocapnia

Reduced amounts of carbon dioxide in the blood, as after HYPERVENTILATION.

hypocapnia

lower than normal partial pressure (tension) of carbon dioxide ( P CO2) in the lung alveoli and in the arterial blood, hence respiratory alkalosis. If severe, can cause dizziness or confusion (by constrictive effect on brain blood vessels, reducing blood flow), disturbances of sensation and tetany (by reducing ionized calcium in the blood). See also hyperventilation.

hypocapnia

abnormally low blood levels of bicarbonate (HCO3-) and reduced buffer activity

hy·po·cap·ni·a

(hī'pō-kap'nē-ă)
Abnormally decreased arterial carbon dioxide tension.
Synonym(s): hypocarbia.
[hypo- + G. kapnos, smoke, vapor]

hypocapnia (hī´pōkap´nēə),

n a deficiency of carbon dioxide in the blood.

hypocapnia

diminished carbon dioxide in the blood.

Exhaustive exercise may have induced a similar or greater degree of vasoconstriction compared with the severe hypocapnia condition, also compared to other stimuli (Delaey and Van de Voorde, 2000; Geiser et al.
24) In the example described above, constant monitoring of blood gases, acid-base balance, inspired oxygen levels and ventilator rates would be necessary to ensure that hyperoxaemia and hypocapnia, as the adverse outcome, do not occur.
When this is combined with the hypocapnia, the pregnant woman ends up with a near normal or somewhat alkalotic pH.
Nasal mechanical ventilation is used to induce hypocapnia and hence central apnoea.

Hypoxia as a result of different mechanisms such as cerebral vasoconstriction, hypocapnia, and decreased cerebral perfusion caused by dehydration seems to be the most acceptable hypothesis in the pathogenesis of cerebral edema in DKA.

i) abnormal patterns of hypocapnia due to altered central and peripheral chemo-receptor drive, and altered cortical input (Gardner, 2004; Jack, Rossiter, Pearson, & Ward, 2004).
The technique involves having the patient learn exercises that reduce both the frequency and the depth of breathing, to induce hypocapnia and reduce minute ventilation.
Researchers have speculated that the chronic metabolic acidosis suffered by patients with ESRD causes these sleep disorders; as the body attempts to correct the acidosis, the patient exhales more carbon dioxide and the hypocapnia that results may be inadequate to fuel respiration (Kimmel, 1989).
2] was monitored via an arterial line and was kept between 38 and 43 mmHg, since both hypocapnia and hypercapnia change the pulmonary vessels resistance.
