Effect of hyperthermia-induced hyperventilation on central fatigue during exercise in heat
Journal of Physical Fitness and Sports Medicine, 2012 Exercise endurance is reduced by heat. Among several factors that influence exercise performance is central fatigue, which appears to be caused by an increase in brain temperature.

Hyperventilation in neurological patients: from physiology to outcome evidence
Current Opinion in Anaesthesiology, 2019 Purpose of review Hyperventilation is commonly used in neurological patients to decrease elevated intracranial pressure (ICP) or relax a tense brain. However, the potentially deleterious effects of hyperventilation may limit its clinical application. The

Cardiopulmonary exercise testing for identification of patients with hyperventilation syndrome
PLoS ONE, 2019 Introduction Measurement of ventilatory efficiency, defined as minute ventilation per unit carbon dioxide production (VE/VCO2), by cardiopulmonary exercise testing (CPET) has been proposed as a screen for hyperventilation syndrome (HVS).

A study to evaluate effect of PEEP and end-tidal carbon dioxide on optic nerve sheath diameter
Indian Journal of Anaesthesia, 2019 Background and Aims: PEEP is commonly used to improve postoperative respiratory outcomes in surgical and ICU patients. It is thought to increase ICP by impending CSF outflow and cerebral venous drainage.
