Chronic intermittent hypoxia in obstructive sleep apnea: a narrative review from pathophysiological pathways to a precision clinical approach
(Facultad de Medicina y Ciencia, 2020)
Obstructive sleep apnea syndrome (OSAS) is a prevalent condition caused by dynamic upper airway collapse during sleep. The pathological impact and consequences are due to chronic intermittent hypoxia (CIH). Hypoxia increases ...
The Effect of Donepezil on Arousal Threshold and Apnea-Hypopnea Index A Randomized, Double-Blind, Cross-Over Study
(Amer Thoracic Soc, 2016)
Rationale: Obstructive sleep apnea (OSA) has multiple pathophysiological causes. A low respiratory arousal threshold (ArTh) and a high loop gain (unstable ventilatory control) can contribute to recurrent respiratory events ...
Supine sleep and positional sleep apnea after acute ischemic stroke and intracerebral hemorrhage
(HOSPITAL CLINICAS, UNIV SAO PAULOSAO PAULO, 2012)
OBJECTIVE: Obstructive sleep apnea is frequent during the acute phase of stroke, and it is associated with poorer outcomes. A well-established relationship between supine sleep and obstructive sleep apnea severity exists ...
Comparison of AutoSet (TM) and polysomnography for the detection of apnea-hypopnea events
(Associação Brasileira de Divulgação Científica, 2000-05-01)
The use of the flow vs time relationship obtained with the nasal prongs of the AutoSetä (AS) system (diagnosis mode) has been proposed to detect apneas and hypopneas in patients with reasonable nasal patency. Our aim was ...
Breathing Patterns and Oxygenation Saturation During Sleep in Children Habitually Living at High Altitude in the Andes: A Systematic Review.
(2021)
Background Human respiratory physiology changes significantly in high altitude settings and these changes are particularly marked during sleep. It is estimated that 170 million people live above 2,500 m in environments ...
Screening of obstructive sleep apnea with empirical mode decomposition of pulse oximetry
(Elsevier, 2014-06)
Detection of desaturations on the pulse oximetry signal is of great importance for the diagnosis of sleep apneas. Using the counting of desaturations, an index can be built to help in the diagnosis of severe cases of ...
A New Algorithm to Score Apnea/Hypopnea Events based on Respiratory Effort Signal and Oximeter Sensors
(Institute of Biomedical Engineering, 2020-08)
Purpose: The aim of this work is to develop and evaluate a new algorithm for the detection of Apnea/Hypopnea events based on the AASM recommendations, with low computational cost and using alternative sensors, such as the ...
Does nocturnal use of a complete denture interfere with the degree of obstructive sleep apnea? A systematic review and meta-analysis
(2021-01-01)
Background: The impact of a complete denture on obstructive sleep apnea is not well understood. Therefore, this study aimed to evaluate the relationship between nighttime use of complete dentures and obstructive sleep apnea ...
Effectiveness of Maxillomandibular advancement (MMA) surgery in sleep apnea treatment: Case report
(Elsevier Science Bv, 2016)
Obstructive sleep apnea (OSA) is characterized by episodes of pharyngeal collapse during sleep. Craniofacial alterations such as retrognathia are often found in OSA patients. Maxillomandibular advancement (MMA) surgeries ...
