Objectives Involuntary apnea episodes in obstructive sleep apnea patients result in selective
potentiation of peripheral chemoreceptor regulation of sympathetic vasomotor tone. Breath …

Sex-related differences in respiratory modulation of sympathetic activity have been observed
in rodent models of sleep apnea [intermittent hypoxia (IH)]. In light of sex disparities in the …

Exposure to hypoxia elicits widespread physiological responses that are critical for
successful acclimatization; however, these responses may induce apparent maladaptive …

Hemodynamics, muscle sympathetic nerve activity (MSNA), and forearm blood flow were
evaluated in 12 normal subjects before, during (1 and 7 h), and after ventilatory …

Baroreflex resetting permits sympathetic long‐term facilitation (sLTF) following hypoxia;
however, baroreflex control of action potential (AP) clusters and AP recruitment patterns …

Chronic exposure to hypoxia (high‐altitude, HA;> 4000 m) attenuates the vasodilatory
response to exercise and is associated with a persistent increase in basal sympathetic nerve …

To investigate possible changes in autonomic regulation of heart rate as a result of
acclimatization to high altitude, indexes of autonomic nervous activity were obtained non …

Exposure to hypercapnic hypoxia (asphyxia), but not hyperoxic hypercapnia, results in
increased sympathetic activity that persists after exposure. To determine the contribution of …

Transient ventilatory response to 3 and 5 breaths of N 2 at rest and during exercise at sea
level was determined in three high altitude natives acclimatized for 10 months and in three …

The combined effects of hypoxia and hypercapnia on the sympathetic nervous system were
investigated in nine healthy subjects. Each subject was exposed to 16 gas mixtures in …
