CPAP, Could Improve Blood Sugar Levels, Study Finds

Treating sleep apnea doesn't just minimize daytime fatigue and disrupted sleep -- it could also help blood sugar levels, according to a small new study.

The findings, presented at a meeting of the American Thoracic Society, show that sleep apnea treatment is linked with better blood sugar levels among people with prediabetes.

"We have studied patients with sleep apnea and prediabetes, a condition defined as higher than normal blood glucose levels but not high enough to be considered diabetes," study researcher Dr. Sushmita Pamidi, M.D., of the Department of Medicine at McGill University, said in a statement. "We found that optimal treatment of sleep apnea with continuous positive airway pressure (CPAP) for two weeks led to significant improvements in glucose levels following an oral glucose challenge without affecting insulin secretion, suggesting an improvement in insulin sensitivity."

The study included 39 people who had both prediabetes and sleep apnea. Researchers had them do two weeks of either CPAP treatment (considered the best treatment for sleep apnea) or a placebo. At the start and end of the study, researchers tested the body's ability to use glucose with an oral glucose tolerance test.

Researchers found that the participants who underwent the CPAP treatment had better glucose metabolism. The findings add "to the current literature by demonstrating that CPAP treatment of sleep apnea in patients at risk for developing diabetes may lower this risk [of Type 2 diabetes], and an assessment for sleep apnea may be appropriate as part of the clinical evaluation of patients with prediabetes," Pamidi said in the statement.

Indeed, past research has shown strong associations between having sleep apnea and having a higher risk for metabolic disorders, including diabetes. Specifically, a study presented at the same meeting last year showed that Type 2 diabetes risk goes up when a person has moderate and severe obstructive sleep apnea.

Freedom to power your CPAP machine no matter where your world takes you!

CPAP therapy can be tough for those who have, up until they started therapy, enjoyed hunting, fishing and camping trips where power sources were not available. But your CPAP therapy doesn’t have to hold you back from those types of outdoor expeditions. The CPAP Shop now offers the C-100 battery, which can provide up to 30 hours of battery power. Now you can comply with your therapy and enjoy the outdoor over-night activities you don’t want to give up.

The C-100 battery is a 1.6 pound lithium ion battery with a scratch resistant shell that can be used any where in the world. It’s FAA approved and comes with a 6 month warranty. To give you an idea of it’s capabilities, the C-100 battery can power the following machines for these time periods on an average pressure of 10cm without the humidifier running:
  • Respironics System One CPAP Machine for 30 hours
  • ResMed S9 CPAP Machine for 22 hours
  • Devilbiss InteliPAP CPAP Machine for 16 hours
Depending on the requirements of your therapy, one battery could get you through an entire weekend.

What it comes with

When you purchase the C-100 battery, you get a soft carrying case and a number of attachments. These attachments include a recharger and connectors that will power most CPAP batteries on the market. Plus, you get a chord that will connect two batteries together for longer power times. The power times can almost double when two batteries are connected. The carrying case even has a pocket to hold the extra battery.

Most of the attachments will fit standard CPAP machines. The ResMed S8 and S9 and the Respironics System One require slightly different components. To find out what components you need for these machines, or what components your machine needs if it is different than the ones listed, just contact Respiratory Solutions for assistance. You can find any battery or cables you need on our website.

Don’t let your CPAP therapy keep you stuck indoors when the C-100 battery will let you continue to enjoy everything the great outdoors has to offer.

Study: Sleep apnea severity is higher in African American men in certain age ranges

A new study suggests that obstructive sleep apnea severity is higher in African-American men in certain age ranges, even after controlling for body mass index (BMI).

"The results show that in certain age groups, after correcting for other demographic factors, the severity of sleep apnea as measured by the apnea-hypopnea index is higher in African-American males than Caucasian males," said James Rowley, PhD, the study's senior investigator, professor of medicine at Wayne State University School of Medicine in Detroit and Medical Director of the Detroit Receiving Hospital Sleep Disorders Center.

Results of multivariate linear regression models show that being an African-American man younger than 40 years of age increased the apnea-hypopnea index (AHI) by 3.21 breathing pauses per hour of sleep compared to a white man in the same age range with the same BMI. For participants between 50 and 59 years of age, being an African-American man increased AHI by 2.79 breathing events per hour of sleep. There was no difference in AHI between African-American and white women.


The researchers analyzed a prospectively collected database of 512 patients studied in the sleep center between July 1996 and February 1999. Inclusion criteria included patients at least 18 years of age, with an AHI greater than 5 events per hour of sleep and a full-night polysomnogram (PSG). Statistical analysis was performed to determine the association between race and AHI while controlling for the effect of confounders and effect modifiers, which included gender, age, BMI and comorbidities. The database included 340 African-American and 172 Caucasian patients.

According to the authors, the mechanism for a racial difference in sleep apnea severity is unclear. They suggested that potential mechanisms include anatomic differences that affect upper airway mechanics and collapsibility, as well as differences in the neurochemical control of breathing.

The American Academy of Sleep Medicine reports that obstructive sleep apnea is a common sleep illness affecting at least four percent of men and two percent of women. It involves repetitive episodes of complete or partial upper airway obstruction occurring during sleep despite an ongoing effort to breathe. The most effective treatment option for OSA is continuous positive airway pressure (CPAP) therapy.
