People who suffer from sleep apnea are recommended to obtain a good night of rest every night to feel recharged the next day. Getting a good nights rest is essential in not feeling daytime sleepiness which is a symptom for those who struggle with sleep apnea (Qaseem et al., 2017). There are recommendations for sleep duration for older adults. Getting a full night sleep can be hard for older adults, especially those who have chronic medical conditions. Many older adults use over the counter drugs to help aid with sleep because it becomes more challenging as time progresses. Older adults tend to go to sleep earlier in the night but are usually woke early in the morning, it is recommended that older adults maintain a consistency of 7-8 hours…show more content…
People who sleep on their back during the night snore louder that people who sleep on their side. In cases of mild or severe obstructive sleep apnea sleeping on your side throughout the night is more beneficial (Kutbay et al., 2015). Efficent sleep has been highly linked to sleep posture, to determine the correlation between the two acoustic reflection technique is used. The assessment of upper airway area by acoustic reflections has been developed in the last 12 yrs, The technique is based on the analysis of sound waves reflected from the airways. Measurement of the amplitudes of the reflections and their times of arrival at the sensing microphone permits construction of a plot of airway area vs distance from the microphone (Köseoğlu et al.,…show more content…
In the study of Bidarian-moniri, Nilsson, Attia, and Ejnell (2015), 14 subjects (11 men and 3 women) who all had a mild case of sleep apnea. Two polysomnographic (PSG) studies were performed. They wanted to see if the mattress and pillow had a positive effect on sleep apnea while sleeping in the prone position. Both PSG study was without any treatment and the second was after 4 weeks of adaptation to the MPP for prone positioning of the body and the head. The results of this study was that sleeping in the prone position and using MPP had a positive benefit on the participants. They had on average 11 less breath pauses episodes than usual and all slept on averah an additional 4 hours per night. This is beneficial information to show that sleeping in the prone positioning using the adequate and comfortable mattress and pillow can be a positive mild treatment for people who suffer with sleep
