Assessment of ventilatory neuromuscular drive in patients with obstructive sleep apnea
(Associação Brasileira de Divulgação Científica, 1998-04-01)
The presence of abnormalities of the respiratory center in obstructive sleep apnea (OSA) patients and their correlation with polysomnographic data are still a matter of controversy. Moderately obese, sleep-deprived OSA ...
Ventilatory frequency indicates visual recognition of an allopatric predator in naive Nile tilapia
(Elsevier B.V., 2003-01-31)
Perceiving a possible predator may promote physiological changes to support prey 'fight or flight'. In this case, an increase in ventilatory frequency (VF) may be expected, because this is a way to improve oxygen uptake ...
Caution for using ventilatory frequency as an indicator of stress in fish
(Elsevier B.V., 2004-04-30)
This study tested the use of ventilatory frequency (VF) as an indicator of stress in the Nile tilapia, Oreochromis niloticus (L.). Firstly, we tested the relationship between VF and plasma cortisol after confinement. ...

Short-Term Sustained Hypoxia Elevates Basal and Hypoxia-Induced Ventilation but Not the Carotid Body Chemoreceptor Activity in Rats
(Frontiers Media Sa, 2018-02-27)
Exposure to chronic sustained hypoxia (SH), as experienced in high altitudes, elicits an increase in ventilation, named ventilatory acclimatization to hypoxia (VAH). We previously showed that rats exposed to short-term(24 ...
Serotoninergic receptors in the anteroventral preoptic region modulate the hypoxic ventilatory response
(Elsevier B.V., 2006-08-01)
Hypothalamus is a site of integration of the hypoxic and thermal stimuli on breathing and there is evidence that serotonin (5-HT) receptors in the anteroventral preoptic region (AVPO) mediate hypoxic hypothermia. Once 5-HT ...

Chronic phenytoin reduces hypoxic ventilatory responses in rats
(2015)
Arterial afferents provide sensory information that participates in the peripheral control of ventilation. The carotid body chemosensory afferents increase their frequency of discharge in response to hypoxia, increasing ...
