Alcohol at bedtime induces minor changes in sleep stages and blood gases in stable chronic obstructive pulmonary disease
Holmedahl, Nils Henrik; Øverland, Britt; Fondenes, Ove; Ellingsen, Ivar; Hardie, Jon Andrew (Peer reviewed; Journal article, 2014-05-17)Purpose/background: The purpose of this study is to explore the effect of a moderate dose of alcohol on sleep architecture and respiration in chronic obstructive pulmonary disease (COPD). Alcohol depresses both hypercapnic ... -
Assessment of nocturnal versus daytime gas exchange in stable COPD. With emphasis on hypoventilation during spontaneous sleep and in sleep influenced by alcohol or zopiclone
Holmedahl, Nils Henrik (Doctoral thesis, 2015-10-28)Background/purpose: Chronic hypercapnic respiratory failure (CHRF) is associated with increased mortality in patients with chronic obstructive pulmonary disease (COPD), and sleep hypoventilation (SH) has been proposed as ... -
Effect of dietary nitrate supplementation on sleep in chronic obstructive pulmonary disease patients
Wisor, Jonathan P.; Holmedahl, Nils Henrik; Saxvig, Ingvild West; Fjeldstad, Odd-Magne; Weitzberg, Eddie; Grønli, Janne; Engan, Harald Kåre (Journal article; Peer reviewed, 2021)Purpose: Poor sleep quality in chronic obstructive pulmonary disease (COPD) is a result of oxygen desaturation secondary to compromised lung function. Nitrate supplementation with dietary beetroot juice is known to elevate ... -
Sleep hypoventilation and daytime hypercapnia in stable chronic obstructive pulmonary disease
Holmedahl, Nils Henrik; Øverland, Britt; Fondenes, Ove; Ellingsen, Ivar; Hardie, Jon Andrew (Peer reviewed; Journal article, 2014-02-27)Purpose: To explore the associations between sleep hypoventilation (SH) and daytime arterial pressures of carbon dioxide (PaCO2), sleep stages, and sleep apneas/hypopneas (AHI) in subjects with chronic obstructive pulmonary ... -
Validation of peripheral arterial tonometry as tool for sleep assessment in chronic obstructive pulmonary disease
Holmedahl, Nils Henrik; Fjeldstad, Odd-Magne; Engan, Harald; Saxvig, Ingvild W.; Grønli, Janne (Peer reviewed; Journal article, 2019-12-18)Obstructive sleep apnea (OSA) worsens outcomes in Chronic Obstructive Pulmonary Disease (COPD), and reduced sleep quality is common in these patients. Thus, objective sleep monitoring is needed, but polysomnography (PSG) ...
