Aims: Ventilation at altitude changes due to altered levels of pO2, pCO2 and the effect on
blood pH. Nocturnal ventilation is particularly exposed to these changes. We hypothesized …

Introduction Ventilation at altitude changes due to altered levels of pO2, pCO2 and the effect
on blood pH. Nocturnal ventilation is particularly exposed to these changes. We …

Conclusion: Our results on cognitive functions are in agreement with literature data on sleep
deprivation. Our data showed that Page 1 Conclusion: Our results on cognitive functions are in …

This study addressed the issue as to how exposure and subsequent acclimatization to high
altitude influences ventilatory control during wakefulness and sleep and considers the …

This study aimed to investigate the effect of periodic breathing (PB) at high altitude on sleep
structure and arterial oxygen saturation (Sa, O2). Five healthy subjects underwent …

Background: There are concerns that even mild hypoxia at altitude has unfavorable health
effects. The current study evaluates the hypothesis that sleep quality and daytime …

Periodic breathing is commonly seen during sleep in healthy humans following ascent to
high altitude. The hyperventilation induced by hypoxia at altitude leads to hypocapnia which …

Background There is an almost universal (> 90%) occurrence of central sleep apnea (CSA)
in newcomers to high altitude (> 5000 m). However, the key factors that determine the …

Although periodic breathing during sleep at high altitude occurs almost universally, the likely
mechanisms and independent effects of altitude and acclimatization have not been clearly …
