Special ventilation masks help sleep apnea, a new Australian study has confirmed by analysing the brain patterns of sleeping people.
Sleep apnea is a disorder that can cause interrupted breathing leading to choking and even death while asleep.
Obstructive Sleep Apnea - Overview
Obstructive sleep apnea should be suspected in overweight middle aged adults who snore loudly and which can cause interruption of breathing for 10 seconds or more and this results in reduced blood o

"Continuous Positive Airways Pressure masks are a common treatment to improve sleep of apneic patients" Dr Kim said. "Special masks to assist with breathing have been prescribed for patients with this disorder for several years, but the feedback from the patients as to their effectiveness was subjective."
Dr Kim and his team analysed sleep patterns of 113 patients with and without the masks, finding that the masks helped improve sleeping patterns in 70 per cent of cases. "Interestingly, from this we found that patients with sleep apnea have a subtle but different brain activity when asleep," Kim says.
People who suffer from sleep apnea toss and turn and wake more frequently than non-sufferers. They are also more likely to snore, wake-up frequently, be obese and are older in age. They are dominantly male with moderate alcohol consumption, daytime sleepiness, hypertension, stroke and metabolic syndrome. Children as young as one or two years can also have the disorder, which can be very worrying for their parents and families.
"Sleep apnea in children may be related to death and loss of brain cells that lead to underdevelopment. So it is vital that medical doctors definitely know that their prescribed method will provide a sound sleep for their patients," Dr Kim commented. "By wearing the mask people can sleep comfortably and without fear of choking in their sleep."

Epworth Sleepiness Scale
Measure your daytime sleepiness using this simple interactive tool, based on Epworth Sleepiness disorder Scale. Excessive Daytime Sleepiness is a type of hypersomnia characterized by persistent sleepiness and lack of energy.
