Association of hypocapnia in children with febrile seizures
Journal of Pediatric Neurosciences, 2018 Febrile seizure is a benign condition in children. Susceptibility genes associated with febrile convulsions have been identified, but the precise pathophysiologic mechanism that triggers febrile seizure is unclear. Using animal models, it has been demonstrated that hyperthermia causes respiratory alkalosis with consequent brain alkalosis and seizures ...

Effects of Respiratory Muscle Warm-up on High-Intensity Exercise Performance
Sports, 2015 Exercise performance is partially limited by the functionality of the respiratory musculature. Training these muscles improves steady-state exercise performance.

Hypocapnia-induced bronchoconstriction [PDF]
, 1988 Hypocapnia-induced bronchoconstriction has been recognized for over J0 years, however, its nechanisms have to date renained essentially unknown. This thesis describes a guínea pig model of hypocapnia-induced bronchoconstriction and elucidates the ...

Hypocapnia and Cerebral Hypoperfusion in Orthostatic Intolerance [PDF]
Stroke, 1998 Background and Purpose —Orthostatic and other stresses trigger tachycardia associated with symptoms of tremulousness, shortness of breath, dizziness, blurred vision, and, often, syncope. It has been suggested that paradoxical cerebral vasoconstriction during head-up tilt might be present in patients with orthostatic intolerance.

São Paulo Medical Journal, 2021 BACKGROUND: The mechanism of exercise limitation in idiopathic pulmonary arterial hypertension (IPAH) is not fully understood. The role of hemodynamic alterations is well recognized, but mechanical, ventilatory and gasometric factors may also contribute ...

The Effect of Hypocapnia on Arterial Blood Pressure [PDF]
Circulation, 1954 In man, hypocapnia induced by hyperventilation causes a drop in arterial pressure. The calculated peripheral resistance is decreased, indicating a net vasodilatation. The forearm blood flow is markedly increased, and the vascular resistance of the forearm is much reduced. Persons with impaired function of the sympathetic nervous system continue to show

Effects of moderate and severe hypocapnia on intracerebral perfusion and brain tissue oxygenation in piglets [PDF]
, 2019 Background: Hypocapnia is a common alteration during anesthesia in neonates. Aim: To investigate the effects of hypocapnia and hypocapnia combined with hypotension (HCT) on cerebral perfusion and tissue oxygenation in anesthetized piglets. Method: Thirty

Hypercapnia does not shorten emergence time from propofol anesthesia: a pilot randomized clinical study [PDF]
Korean Journal of Anesthesiology, 2018 Background The elimination of anesthetic agents is a decisive factor in the emergence from general anesthesia. In this pilot study, we hypothesized that hypercapnia would decrease the emergence time from propofol anesthesia by increasing cardiac output ...

Effects of changes in end‐tidal PO2 and PCO2 on neural responses during rest and sustained attention
Physiological Reports, 2021 Impairments of cognitive function during alterations in arterial blood gases (e.g., high‐altitude hypoxia) may result from the disruption of neurovascular coupling; however, the link between changes in arterial blood gases, cognition, and cerebral blood ...
