LTL was positively correlated with sleep efficiency, total sleep time, basal, minimum and maximum oxygen saturation. (oncotarget.com)
The lack of oxygen prompts the brain to wake the patient from a deep sleep so his airway reopens. (perthcpap.com.au)
It generally takes your brain 10 or more seconds to realize it is deprived of oxygen before it briefly rouses you from sleep so that you can reopen your airway. (southcentraldentistry.com)
People with obstructive sleep apnea (OSA) have disrupted sleep and low blood oxygen levels. (texasdentalpa.com)

A growing number of studies, in animal models and humans , have highlighted the link between sleep and Alzheimer's disease (AD) pathophysiology. (bvsalud.org)

Nearly one billion people worldwide suffer from sleep apnea. (rivervalleysmiles.com)
Almost 7% of Americans suffer from obstructive sleep apnea or OSA. (sleepapneatreatment.com)

If the AHI or RDI is calculated based on less than 2 hours of continuous recorded sleep, the total number of recorded events to calculate the AHI or RDI during sleep testing is at least the number of events that would have been required in a 2-hour period. (medscape.com)
We are proposing to modify the criteria for a positive sleep study to remove the requirement for a minimum two hours of continuous recorded sleep and instead recognize shorter periods of continuous recorded sleep if the total number of recorded events during that shorter period is at least the number of events that would have been required in a two hour period.

A simple yet effective option is the use of a continuous positive airway pressure (CPAP) device to prevent the airway from closing during sleep as it provides a continuous supply of compressed air. (perthcpap.com.au)

Is there a relationship between chronic rhinosinusitis and new onset obstructive sleep apnea (OSA) in the World Trade Center Population? (cdc.gov)
With the onset of sleep, the rate of breathing becomes slower and the volume of each breath decreases. (theanesthesiaconsultant.com)

When obstructive sleep apnea occurs, the tongue is sucked against the back of the throat. (texasdentalpa.com)

The Sleep Wellness Center at Island Hospital in Anacortes, WA is a stand-alone state-of-the-art facility dedicated to helping both adult and pediatric patients get the sleep they need to improve their. (whidbeylocal.com)

The aim of this study is to investigate the differences in polysomnographic and cephalometric features according to positional and rapid eye movement (REM) sleep dependencies in obstructive sleep apnea patients. (researchsquare.com)
The subjects were categorized into positional and non-positional, and REM-related and not-REM-related OSA groups according to positional and REM sleep dependency on severity of sleep apnea. (researchsquare.com)
Anatomical factors maybe more closely related to REM sleep than positional dependency. (researchsquare.com)
9 Positional therapy changing to the non-supine position during sleep can be a simple and effective measure in reducing AHI, but unsatisfactory for patients with non-positional OSA, emphasizing the need of further related investigations for accurate diagnosis. (researchsquare.com)

There is a progressive decrease in sympathetic activity, blood pressure (BP), stroke volume, heart rate, cardiac output, and systemic vascular resistance, during deeper NREM sleep stages [ 4 ]. (hindawi.com)

These mild hindrances you now feel during sleep can lead to disasters if left unchecked. (sleepapneatreatment.com)

Reduction of tone in this musculature and loss of compensatory reflex dilator mechanisms during deep sleep result in the airway obstruction. (medscape.com)
The changes in obstruction improvement, sleep characteristics and performance scale were also associated with training time, as detected by Pearson's correlation analysis. (frontiersin.org)
The patient underwent drug-induced-sleep-endoscopy to further investigate the source of obstruction and was found to have obstructive tissue at the supraglottis and base of tongue. (imedpub.com)
