The effects of hypocapnia on cardiac electrical activity and heart function and its relevance to the diagnosis of coronary artery disease
… was to explore a new technique for inducing hypocapnia in resting subjects and investigate whether this technique has any clinical applications in the diagnosis of coronary artery disease. In 18 healthy subjects, the effects of hypocapnia, induced by mechanical hyperventilation (in 21% or 15% …

Neurovascular implications of life-long exposure to contact in rugby union; the link to cognition
… was assessed using hypercapnia (CVRCO2HYPER) and hypocapnia (CVRCO2HYPO). Cognition was assessed via neuropsychometric tests and screened for mild cognitive impairment (MCI) using the Montreal Cognitive Assessment (MoCA). In-season notational analysis observed all match events throughout each game …

Effects of Cerebral Blood Flow and Temperature on Executive Function During Moderate Hyperthermia
… baseline CBF in the isocapnic trial during the hypocapnia-induced CBF reduction. Repeated measures analysis of variance indicated that an increase of 5°C in mean skin temperature impaired working memory regardless of rectal temperature. The results also indicated that an increase of 1.5°C in …

The behavioural physiology of diving animals, in particular tufted ducks (Aythya fuligula), and the implications for models of optimal diving
… ducks, while pre-dive hyperventilation caused hypocapnia suggesting carbon dioxide is more often a limiting factor on dive duration. Oxygen uptake was not affected by hypercapnic exposure between dives and minimally affected by hypoxia, however dive time budgeting changed in both cases. This …

Isocapnic hyperventilation in anaesthesia practice. Clinical and experimental studies
Abstract Background: Isocapnic hyperventilation (IHV) has been shown to shorten recovery time after volatile anaesthesia by accelerating elimination of inhalational agents by increasing minute ventilation while maintaining normal carbon dioxide (CO2) levels. It has also been shown that IHV reduces …
