Severe desaturations increase psychomotor vigilance task-based median reaction time and number of lapses in obstructive sleep apnoea patients

S Kainulainen, B Duce, H Korkalainen… - European …, 2020 - Eur Respiratory Soc
Current diagnostic parameters estimating obstructive sleep apnoea (OSA) severity have a
poor connection to the psychomotor vigilance of OSA patients. Thus, we aimed to investigate …

Differences in arousal probability and duration after apnea and hypopnea events in adult obstructive sleep apnea patients

T Leppänen, A Kulkas, A Oksenberg… - Physiological …, 2018 - iopscience.iop.org
Objective: In obstructive sleep apnea (OSA), breathing cessations are often followed by
arousals, leading to sleep fragmentation and thus impaired sleep quality. Arousals and …

Study Objectives: The aim was to investigate how the severity of apneas, hypopneas, and
related desaturations is associated with obstructive sleep apnea (OSA)-related daytime …

I Fietze, K Dingli, K Diefenbach… - European …, 2004 - Eur Respiratory Soc
The current study investigated the night-to-night variability and diagnostic accuracy of the
oxygen desaturation index (ODI), as measured by ambulatory monitoring, in the diagnosis of …

Most obstructive sleep apnoea patients exhibit vigilance and attention deficits on an extended battery of tests

S Mazza, JL Pepin, B Naegele, J Plante… - European …, 2005 - Eur Respiratory Soc
Excessive daytime sleepiness, fatigue and altered attention are often experienced by
obstructive sleep apnoea (OSA) patients. Although attentional problems are presumably …

Effect of different oxygen desaturation threshold levels on hypopnea scoring and classification of severity of sleep apnea

S Myllymaa, K Myllymaa, S Kupari, A Kulkas… - Sleep and …, 2015 - Springer
Purpose Recently, there has been a debate about the rules used to score hypopnea events.

More severe hypoxemia is associated with better subjective sleep quality in obstructive sleep apnea

MN Wu, CL Lai, CK Liu, LM Liou, CW Yen… - BMC pulmonary …, 2015 - Springer
