Has your physician told you that you are suffering from Positional Obstructive Sleep Apnea? So what does that mean in layman terms?
If you have already been for a sleep test, and have been diagnosed with Obstructive Sleep Apnea, you would be familiar with the acronym AHI which stands for Apnea Hypopnea Index, which basically means the average number of apneas or hypopneas you presented with in an hour.
Apnea = Reduction of airflow of at least 90% for a duration of 10 secs or more.
Hypopnea = Reduction of airflow of at least 30% for a duration of 10 secs or more, accompanied by a fall of oxygen saturation of at least 3%.
Positional Obstructive Sleep Apnea is diagnosed when your AHI in the lateral position i.e. when you are lying on your side, is at least 50% less than your AHI in the supine position i.e. when you are lying on your back.
For example, if your AHI in the supine position is 28/hr, and is 2/hr in the lateral position, you may be having the Positional Obstructive Sleep Apnea Syndrome.
SO WHAT IS POSITIONAL THERAPY?
Positional Therapy make use of simple devices to prevent you from rolling onto you back when you are asleep.
Previously, patients with Positional Obstructive Sleep Apnea would be advised to sew tennis balls on to the back of their T-shirts. Ouch! It sounds painful and I am sure it is painful to roll on your back with that tennis ball around.
Today, there are less painful devices such as Zzoma Positional Therapy device, which keeps you in lateral position for the entire night.

IS IT UNCOMFORTABLE?
To be honest, probably so, unless you are a side-sleeper. But then again, if you are a side-sleeper, you probably would not need this device in the first place.
It takes some getting used to, possibly a week or two, per all other forms of treatment for Obstructive Sleep Apnea. PAP therapy requires some getting used to, Oral Appliance Therapy requires some getting used to, even surgeries require a recovery period.
CAN I HAVE A TRIAL OF THE ZZOMA?
Sure! That is what we are here for. But firstly, we would need to take a look at your sleep test report, and may need to link up with your physician to confirm the suitability of Positional Therapy for you.
HOW WOULD I KNOW IF IT IS EFFECTIVE?
During the 2-week trial which would cost SGD50 nett, you would be required to put on the Zzoma every night when you sleep. This is to enable you to acclimatize or get used to possibly having to sleep on one side for the entire night.
At the end of the 2-week trial, you will have to pick up the ResMed ApneaLink Home Sleep Test Device from our office, to be worn together with the Zzoma for just one night. The ResMed ApneaLink comes with positional sensors which will enable us to know the position you were sleeping in (it is of course supposed to be lateral if you have the Zzoma on), and to measure the effectiveness of Positional Therapy on you by comparing your AHI for the night, with that of your original sleep test. You will need to bring both the Zzoma and the ResMed ApneaLink back to us within 3 day from the last day of your trial.
