Obstructive Sleep Apnea Research Paper
The pharyngeal airway plays a significant role in the pathogenesis of obstructive sleep apnea (OSA), thus it is extensively studied in patients suffering from this condition. Obstructive sleep apnea is a condition in which there is recurrent partial or complete obstruction of the upper airway resulting in periods of absent airflow (apnea) or diminished airflow (hypopnea).

The severity of obstructive sleep apnea can be measured by the apnea index (AI) or the apnea-hypopnea index (AHI). These indices are defined as the number or apneas or apneas and hyponeas, respectively, per hour during sleep.3,5 Another commonly used index is the respiratory disturbance index (RDI), which, in addition to apneas and hypopneas, other less evident respiratory

    After conducting a mini “study” of whether alternate nostril breathing helps people with sleep issues as opposed to normal breathing at bed time, it was concluded that, yes, alternate nostril breathing at bed time does help to relax a person and put them in a more sound sleep than normal breathing. In the personal study conducted, three nights were done under normal breathing circumstances and three nights with the alternate nostril breathing technique applied. The three nights done under normal breathing proved to be more restless and more rousing during sleep than the three where the alternate nostril breathing (ANB) technique was done. Under the influence of the ANB, less restlessness and a more sound sleep were observed. All in all, even though the data tracking sheet shows more time to fall asleep each night and a lot of restlessness, it was still a more refreshing morning on these days than the days than when the normal breathing was done. As a result of the study, it is believed that ANB does work as an alternative to drugs as a sleep aid.…

    This is addiction information to my sleep apnea claim. Prior to finding out, I had been suffering from sleep apnea before retiring from the Military. I was going to the doctors with complaints of stroke like symptoms after exercising (PT); with vision problems and headaches for years. Not knowing I was not getting a complete night of sleep. The symptoms would last for about 30 to 40 minutes, would go away after getting some rest, but I would continue to have a headache for three to four days.
