Obstructive Sleep Apnoea (OSA)

An Obstructive Sleep Apnoea (OSA) occurs when there is an involuntary blockage of the upper respiratory tract, and is one of the most common forms of respiratory disorders.

With the aging of the human body, the musculature of the soft palate progressively looses it's tone, collapses on and off during sleep, and blocks the respiratory tract in small intervals. These blockages, otherwise called Apnoeas, could last from up to 10 seconds, occur perhaps 5 times an hour,  and occurs quite commonly, does not qualify as an illness. When your spouse/partner notes that you have intermittent snoring and notes especially your intermittent waking, as your ability to breathe is arrested at intervals, you need no further proof that you are suffering from Sleep Apnoea.  These alarming signs are ironically a wake-up call, signalling the creeping in of Sleep Apnoea. Left undetected, could develop into OSAS.

For those affected, when you are alerted by a family member, it would be wise for you to undertake a sleep-study. When your reports indicate a light to medium Obstructive Sleep Apnoea, and you seemingly fulfill all the criteria for a CPAP therapy, the Velumount Method could be your ideal, cost-effective solution, to prevent you from developing a full fledged Sleep Apnoea Syndrome.


Symptoms of Sleep Apnoea and Severity

Habitual Snoring

The weakening and narrowing of the upper respiratory tract leads to an air turbulence effect, thus producing loud and noisy vibrations.

Obstructive Sleep Apnoea (OSA)

This is a mechanical problem. Short pauses (Apnoeas), lasting for 10 seconds or more at a stretch, and more than 10 such pauses every hour.  At this range, there is no increased risk of daytime fatigue.

Obstructive Sleep Apnoea Syndrome (OSAS) Mild Up to 20 Apnoeas / Hour,  increased risk of daytime fatigue.
Obstructive Sleep Apnoea Syndrome (OSAS) Moderate 20 - 40 Apnoeas / Hour, increased risk of daytime fatigue.
Obstructive Sleep Apnoea Syndrome (OSAS) Severe Over 40 Apnoeas / Hour, increased risk of daytime fatigue.
Central Sleep Apnoea (CSA) As against the above mentioned mechanical problem, CSA is a communication problem, with Apnoeas lasting for more than 10 seconds at a stretch, and failing or decreased breathing ability. This is caused by various other underlying health conditions, related to heart or brain disorders - afflictions such as stroke, or circulation disorders.

Undine Syndrome

Is a rare disease, due to a severely impaired central autonomic control of breathing and dysfunction of the Autonomic Nervous System. 


Central Sleep Apnoea

Central Sleep Apnoea occurs when the brain temporarily fails to signal the muscles responsible for controlling breathing. Unlike Obstructive Sleep Apnoea, which can be considered a mechanical problem, Central Sleep Apnoea is more of a communication problem. CSA affects about 5% of patients suffering from Sleep Apnoea. Causes for these failures in sending respiratory signals could be various factors, mostly related to heart disorders, and sometimes related to brain disorders. For patients with such pre-existing conditions purporting primary CSA, the Velumount Method would not be suitable.

Noteworthy to mention is that, it IS possible that a patient with OSA undergoing CPAP therapy could suddenly develop increased CSA. One will then have to address the problem of 'Complex Sleep Apnoea' (CompSA). Not much data is yet available on this problem. Experts however, based on their past experiences would opine that about 5 - 10% patients under CPAP therapy could develop this condition. For such affected patients, a medically monitored therapy with Velumount could prove meaningful.
