The Apnea-Hypopnea Index (AHI) is a measure of severity in obstructive sleep apnea. It is calculated as the number of times per hour that the airway partially or completely collapses, associated with a drop in oxygen levels. Partial collapse is labeled a hypopnea, whereas complete collapse is labeled an apnea. CPAP treatment uses air pressure delivered ...

Yes, you can get a full face mask and then it wont matter if you are breathing through your mouth or not. I would contact your medical equipment provider again and see what they have in options for full face masks. Personally I use Quattro full face mask and have no issues with it. You can look here for an idea of what masks are out there to chose from. ...

As a patient, Mayo Clinic physicians have indicated to me, as a patient, that weight loss can improve your position (reduce / eliminate apnea+hypoxia events) and reduce the need and possibly eliminate the need for CPAP therapy.

As a sufferer of obstructive sleep apnoea (OSA) myself, I was diagnosed using an in home sleep study. The results can be the same using a lab sleep study but that may depend on the person undergoing the study. Some have problems relaxing enough when not in their own home. In home sleep studies, of course, are cheaper to conduct as there are no additional ...

There are specialists who do different degrees of positional assessments - specifically orthodontists, dentists, or maxillofacial surgeons (usually those who specialize in TMJ). Also, some practicing D.O. physicians and massage therapists who specialize in cranial OMT may address positioning. OSA is not the only potential complication of poor mandibular ...

As I pointed out in the comments under your other related question, mandibular advancement devices are not a new idea. From my experience as a diagnosed sufferer of chronic OSA (Obstructive Sleep Apnoea), I underwent the home sleep study you described and it was not a "go/no go" test for CPAP, it was a yes/no test for sleep apnoea. It was suggested in 2014 ...

Schnirman, et al. (2017) talks of such a risk. The mask, which touches the patient’s face, should be cleaned daily with distilled water. Rinsing the face mask or tubing with tap water, instead of using distilled water, or adding tap water in the humidifier is a potential source of legionella colonization. Sterile distilled water cannot sustain legionella ...

Although not a "respiratory stimulant" in the sense of stimulating muscles of respiratory, hypoglossal nerve stimulation devices, such as INSPIRE, can stimulate your tongue to move forward when sleeping, which opens up the upper airway and allows for better breathing. The STAR trial showed that hypoglossal nerve stimulation can reduce sleep apnea ...

Yes, it's true. A relationship does exist between grinding the teeth and sleep apnea. The term bruxism(sleep bruxism) is used for grinding the teeth during sleep at night. In a study it was seen that the patients with obstructive sleep apnea syndrome also demonstrated with sleep bruxism. Interestingly treating the sleep apnea syndrome may also prevent sleep ...

AFAIK: It's pretty normal as long that you don't have trouble getting back to sleep. Try to google 'sleep cycles' to learn more about how the brain functions. Basically we have, I recall, 4 stages of sleep. Stage 4 is what is known as REM sleep, and this is where vivid dreaming happends, stages 3 is deep sleep and so on ... The point I'm getting to, is that ...
