Slow breathing reduces chemoreflex
response to hypoxia and hypercapnia, and increases baroreflex sensitivity.
2005) found a reduction in the ventilatory response to hypercapnia in swimmers after 12 weeks of inspiratory and expiratory muscle training program but no differences with their control group, indicating that the changes in chemoreflex
threshold were the result of the TS.
The mechanisms for the activation of the SNS during 24 hour are not fully understood, but one possibility is that increased chemoreflex
gain by OSA results in tonic chemoreflex
activation even during normoxia, with consequent increased sympathetic activity (26).
The exact mechanism of improvement is not completely understood, but might be related to improvement in airway structure, neurophysiologic regulation of respiration, and chemoreflex
control of breathing during wakefulness in healthy men and women.
1,16) LPR has also been associated with sudden infant death syndrome, (13,26-34) probably mediated through the laryngeal chemoreflex
E]) and systemic blood pressure are elevated by a chemoreflex
stimulated by buildup of metabolic byproducts in the ischemic limbs; the most likely candidate is hydrogen ion concentration ([H.
It thus follows that S100B cannot be increased solely during conditions of cerebral ischemia, and hence cerebral damage, but it is better related to fetal hypoxic stress, which leads to redistribution of blood flow by triggering a chemoreflex
, and the Bezold-Jarisch reflexes (Pliquett et al.
