Accurate Deep Learning-Based Sleep Staging in a Clinical Population with Suspected Obstructive Sleep Apnea
Korkalainen, Henri; Aakko, Juhani; Nikkonen, Sami; Kainulainen, Samu; Leino, Akseli; Duce, Brett; Afara, Isaac Oluwaseun; Myllymaa, Sami; Töyräs, Juha; Leppänen, Timo (Institute of Electrical and Electronics Engineers (IEEE), 2019)The identification of sleep stages is essential in the diagnostics of sleep disorders, among which obstructive sleep apnea (OSA) is one of the most prevalent. However, manual scoring of sleep stages is time-consuming, ...Tieteelliset aikakauslehtiartikkelit

Comparison of the effect of weight change, simulated computational continuous positive airway pressure treatment and positional therapy on severity of sleep apnea
Kulkas, Antti; Duce, Brett; Töyräs, Juha; Seppä, Juha; Leppänen, Timo (Wiley, 2021)Weight loss, continuous positive airway pressure (CPAP) and positional therapy (PT) are important treatments in obstructive sleep apnea (OSA). Although all of these reduce the apnea–hypopnea index (AHI) effectively, the ...Tieteelliset aikakauslehtiartikkelit

Gamma Power of Electroencephalogram Arousal is Modulated by Respiratory Event Type and Severity in Obstructive Sleep Apnea
Pitkanen, Henna; Duce, Brett; Leppänen, Timo; Kainulainen, Samu; Kulkas, Antti; Myllymaa, Sami; Töyräs, Juha; Korkalainen, Henri (IEEE, 2022)Objective: We aimed to investigate the differences in electroencephalogram (EEG) gamma power (30–40 Hz) of respiratory arousals between varying types and severities of respiratory events, and in different sleep stages. ...

Increased nocturnal arterial pulsation frequencies of obstructive sleep apnoea patients is associated with an increased number of lapses in a psychomotor vigilance task
Kainulainen, Samu; Duce, Brett; Korkalainen, Henri; Leino, Akseli; Huttunen, Riku; Kalevo, Laura; Arnardottir, Erna S; Kulkas, Antti; Myllymaa, Sami; Töyräs, Juha; Leppänen, Timo (European Respiratory Society (ERS), 2020)Objectives Besides hypoxaemia severity, heart rate variability has been linked to cognitive decline in obstructive sleep apnoea (OSA) patients. Thus, our aim was to examine whether the frequency domain features of a ...Tieteelliset aikakauslehtiartikkelit

Longer apneas and hypopneas are associated with greater ultra-short-term HRV in obstructive sleep apnea
Hietakoste, Salla; Korkalainen, Henri; Kainulainen, Samu; Sillanmäki, Saara; Nikkonen, Sami; Myllymaa, Sami; Duce, Brett; Töyräs, Juha; Leppänen, Timo (Springer Science and Business Media LLC, 2020)Low long-term heart rate variability (HRV), often observed in obstructive sleep apnea (OSA) patients, is a known risk factor for cardiovascular diseases. However, it is unclear how the type or duration of individual ...Tieteelliset aikakauslehtiartikkelit

Longer duration electroencephalogram arousals have a better relationship with impaired vigilance and health status in obstructive sleep apnoea
Duce, Brett; Kulkas, Antti; Töyräs, Juha; Terrill, Philip; Hukins, Craig (Springer Science and Business Media LLC, 2020)Purpose Obstructive sleep apnoea (OSA) is a prevalent sleep disorder with significant health consequences. Sleep fragmentation is a feature of OSA and is often determined by the arousal index (ArI), a metric based on the ...Tieteelliset aikakauslehtiartikkelit
