OBJECTIVE Nocturnal periodic breathing occurs more frequently in men than in women with
various clinical and pathophysiologic conditions. The mechanisms accounting for this sex …

We provide an updated review on the current understanding of breathing and sleep at high
altitude in humans. We conclude that:(1) progressive changes in pH initiated by the …

High‐altitude exposure is characterized by the appearance of periodic breathing during
sleep. Only limited evidence is available, however, on the presence of gender‐related …

Rationale: Central sleep apnea (CSA) is pervasive during sleep at high altitude,
disproportionately impacting men and associated with increased peripheral …

Altitude illness remains a major cause of mortality. Reduced chemosensitivity, irregular
breathing leading to central apnoeas/hypopnoeas, and exaggerated pulmonary …

Abstract Study Objectives To assess altitude-induced sleep and nocturnal breathing
disturbances in healthy lowlanders 40 y of age or older and the effects of preventive …

Peripheral chemoreflex mediated increases in both parasympathetic and sympathetic drive
under chronic hypoxia may evoke bradyarrhythmias during apneic periods. We determined …

Purpose The occurrence of periodic breathing (PB) at high altitude during sleep and the
quality of sleep are individually different and influenced by multiple factors including sex …

To determine whether nocturnal periodic breathing (PB) at altitude is due primarily to
unstable control of ventilation or the inability to maintain stable sleep states, we performed …

We investigated if the number and duration of breathing events coupled to upper airway
collapsibility were affected by the time of day. Male participants with obstructive sleep apnea …
