SpletSustained hyperventilation produces acral and circumoral paresthesias and lightheadedness in anxious individuals and can be maintained by relatively normal ventilatory patterns once established. These symptoms are due to hypophosphatemia and respiratory alkalosis, the latter reducing CBF and causing localized tissue hypoxia.

These results provide reference data for the diagnosis of chronic respiratory … SpletMean time from hyperventilation onset to a first absence was 52 seconds (median 32 seconds). The vast majority (85.5%) had an absence within 90 seconds. Most (68%) children sustained a single event. All eight children with posthyperventilation seizures had experienced at least one event during hyperventilation. Conclusions: SpletThere is a close relationship between an elevated arterial ammonia level and the development of encephalopathy, with the risk of intracranial hypertension greatest when there is a sustained level ... soft cursos

This report describes a … Splet01. dec. 2002 · Sustained hyperventilation has a time-limited effect on cerebrovascular dynamics. We investigated whether this effect was similar among brain regions by measuring regional cerebral blood volume (CBV) with steady-state susceptibility contrast magnetic resonance imaging during 3 h of hyperventilation. softcult bandSplet12. okt. 2004 · When healthy volunteers hyperventilate for a prolonged time-interval their cerebral blood flow (CBF) shows a relatively rapid adaptation starting almost immediately after onset of hyperventilation [ 1, 2 ], with recovery of CBF to approximately 90% of baseline values within 4 h of sustained hypocapnia [ 3 ]. soft cup body briefer

"Splet01. avg. 2000 · Effects of sustained hyperventilation on arterial baroreceptor gain are unknown. The effects of hyperventilation-induced reduction in baroreflex function may facilitate simultaneous increases in BP, heart rate, and sympathetic activity during dynamic exercise (13, 18) and chemoreceptor activation (21, 22). We therefore tested the … " - Sustained hyperventilation
