is commonly a manifestation of acute anxiety and may accompany a panic attack.
should only be used as a rescue measure to prevent tentorial herniation when all other modalities have failed to alleviate an acute rise in ICP.
The finding on the issue of hyperventilation
suggests that the effect of this manipulation occurred exclusively at a physiologic level and was not attributable to either distraction or other psychological causes.
These patients usually require maximum medical therapy and hyperventilation
strategies or an emergent craniotomy to prevent cerebral ischemia.
Moreover, discharges can also develop some degree of irregularity towards the end of the seizure, particularly during sleep, hyperventilation
, sleep and drowsiness (Kernan, Asarnow & Siddarth, 2012).
The purpose of this study was to intraoperatively compare the effects of moderate hyperventilation
on the jugular bulb oxygen saturation (SjO [sub]2 ), cerebral oxygen extraction ratio (O [sub]2 ER), mean arterial blood pressure (MAP), and heart rate (HR) in patients with a supratentorial tumor under different anesthetic regimens.
The role of Capnography aided controlled hyperventilation
and deliberate hypocapnia during neuroanaesthesia is integral to maintenance of optimal surgical environment and neuroprotection.
The kind of hyperventilation
of the moment was really extraordinary - and it was at that moment in time when people in America just literally couldn't get more excited about Downton Abbey.
In preclinical testing with both acute and chronic dosing, the product, a 5HT1A agonist and D2 agonist/antagonist, has been associated with a 70 to 85% reduction of apneas and hyperventilation
Extended breath-holding after hyperventilation
is not a safe procedure, and the Navy community is not immune to the danger of this phenomenon.
The court also heard she suffered symptoms including hyperventilation
while still at the clinic but was discharged and took a taxi to a friend's house.
The men became unconscious underwater after performing intentional hyperventilation
syndrome (HVS) is a breathing pattern disorder which is often undiagnosed due to its multi-systemic and apparently unrelated symptoms (Mooney and Candy 2008, van Doorn et al 1983).
Although a healthy person will not desaturate to the point of cyanosis (turning blue) even with rigorous training, we were able to see O2 saturation fluctuations in response to warm-up, intense activity, active recovery, hyperventilation
, breath holding, and super-intense activity.
Hence, the impact of maximal hyperventilation
on a postural stability of athletes could be stronger versus non-athletes.
