How important is CPAP compliance for individuals afflicted with Obstructive Sleep Apnea (OSA)?   

Below is a snippet of a study that was completed to try and predict who was going to become a compliant CPAP user based on information from their sleep study.

Extensive use of continuous positive airway pressure (CPAP) has positive clinical benefits for most patients with obstructive sleep apnea (OSA). However, patient adherence is a major limiting factor to the effectiveness of CPAP treatment. This study determined the potential factors affecting the willingness of patients with OSA to undertake CPAP treatment by comparing the polysomnographic parameters (Sleep Study) recorded during diagnosis (without CPAP) and titration (with CPAP).  A total of 312 patients who were diagnosed with moderate and severe OSA, were divided into persistent users and nonusers of CPAP according to their use of in-home CPAP during a 7-day CPAP trial.  Among the patients, 146 (46.8%) became persistent CPAP users. A 10% improvement of oxygen desaturation index (ODI) and a 10% increment in deep sleep percentage increased the chance of persistent CPAP use.

Sound waves can improve sleep and memory, study says



Sound wave therapy can improve sleep and memory, according to a new study fromNorthwestern Medicine in the US.

According to Psych Central, Neuroscience graduate student Nelly Papalambros wanted to find out if there was a non-invasive way to improve sleep quality, because of its many effects on health. Poor sleep has been linked to everything from cognitive problems (including memory issues and difficulty concentrating) to heart attack and disease, while insomnia drastically increases the risk of accident and injury.

Papalambros recruited study participants with an increased risk of heart disease, and measured their baseline stats and sleep patterns while they stayed at a sleep research centre overnight. She then tested whether playing a low-grade static noise could improve their quality of sleep. This sound was developed by Giovanni Santostasi and is personalised in order to be more effective.

Wait, Americans say they’re getting almost 9 hours of sleep a night? That can’t be right.

Sleep is the white whale of American life, the alpha and the omega of all that we are and all that we could possibly be, if only we could get a little more rest. The lack of sleep among Americans is a “public health epidemic,” according to the Centers for Disease Control and Prevention. Somewhere between 50 million and 70 million Americans suffer from sleep disorders or deprivation, reports the Institute of Medicine of the National Academy of Sciences. The benefits of sleep are fairly obvious (you are well rested); the drawbacks of not sleeping enough are legion (a lack of sleep has been linked to making children more obese, preventing the brain from flushing out toxins and generally increasing a person’s risk of developing all sorts of major illnesses).

The desire for a better, deeper, more restful sleep has spurred more and more people to purchase and use sleep aids.
