Hypocapnia does not alter hepatic blood flow or oxygen consumption in patients with head injury.
International audienceOBJECTIVE: To evaluate the effects of hypocapnia on the systemic and hepatic circulations and oxygenation values in patients with head injury. DESIGN: Open-label, prospective study.

Effects of hypoxia and hypocapnia on brain redox balance in ducks
Low arterial CO2 tension (PaCO2) experienced by birds during high-altitude flight may result in cerebral vasoconstriction with reduced cerebral O2 delivery.

Effects of moderate hypoxemia and hypocapnia on CSF [H+] and ventilation in man
The effects of 26 h of normoxic hypocapnia (PaCO2, 31 MMHg) vs. 26 h of hypocapnia plus hypobaric hypoxia (PaCO2 32, PaO2 57 mmHg) were compared with respect to: a) CSF acid-base status; and b) the spontaneous ventilation (at PIO2 145 mmHg) which ...

Pattern and mechanism of airway response to hypocapnia in normal subjects
We examined the bronchoconstriction produced by airway hypocapnia in normal subjects. Maximal expiratory flow at 25% vital capacity on partial expiratory flow-volume (PEFV) curves fell during hypocapnia both on air and on an 80% helium- 20% oxygen ...

Blood sugar response of dogs exposed to hypoxemia and/or hypocapnia
Blood sugar levels of 93 dogs are reported. In animals in which respiration was controlled and hypoxemia or hypocapnia induced for 15 minutes, there was no change in blood sugar.

Failure of Perception of Hypocapnia: Physiological and Clinical Implications
Hyperventilation causes hypocapnia and respiratory alkalosis and thereby predisposes to coronary vasoconstriction and cardiac arrhythmia. Diagnostic methods for use between episodes have not been established.

Latent class growth analysis of dynamic PaCo2 patterns and clinical outcomes in acute brain injury
To analyze dynamic patterns of arterial carbon dioxide partial pressure (PaCO₂) using latent class growth analysis in acute brain injury patients and investigate their associations with 28-day ICU mortality and 60-day in-hospital mortality.
