Have you watched yourself snore?? It may help…

Have you been told that you snore or stop breathing in your sleep? Have you been shown that you do this? If you have watched a video of yourself snoring or stopping breathing in your sleep, that video may actually be a helpful tool for you.

Aloia et al. from the National Jewish Heath in Denver recently released some preliminary findings at the Associated Professional Sleep Societies. They are currently performing a randomised controlled trial. The trial consists of patients with an average age of 50 years old,  who have recently been diagnosed with Obstructive Sleep Apnoea (OSA). These patients were split into three groups:

  • Those that watched a video of themselves snoring and gasping for air
  • Those that watched a video of others snoring and gasping for air
  • Those who watched no video

All patients received routine CPAP education.

What they found was that those that watched video of themselves used CPAP for a mean of 6.5hrs per night, those that watched someone else used it for 4.1hrs and those who didn’t watch anyone had 3.5 hrs of usage per night. This usage was measured over the first 90 days of therapy.

These findings are quite interesting, and in future (with more data) video may become an important tool in CPAP education.

MATRx and Mandibular Advancement Splints; changes to sleep studies coming?

Filed under: Blog — Tags: , , , , — Phil Teuwen @ 3:47 am

Mandibular Advancement Splints are a common treatment for Obstructive Sleep Apnoea (OSA). These look much like the mouthguards that your favourite football stars wear on the weekend. These work by having two plates, these plates (or mouth guards) sit over your teeth (top and bottom) and connect help keep your lower jaw forward. It is thought that by stabilising and/or protruding the lower jaw forward, the MAS devices prevent the soft tissue of the upper airway from collapsing and thus treating OSA.

MAS – the pro’s:

  • Patient compliance is generally pretty good. The devices are easy to wear and can be a comfortable sleep therapy

MAS – the con’s:

  • These don’t always work for every patient, i.e. the efficacy of therapy is lower than other OSA treatment
  • Can have side effects on the jaw, bite and dentition

MAS – the summery:

  • What these devices may lose in efficacy they may gain in compliance
  • Its hard to know if the MAS will work prior to having the device made, can be a $2000 treatment that may or may not treat OSA
  • A fully fitted MAS device can cost a similar amount to CPAP (CPAP = gold standard treatment for OSA

 

MATRx

 

Recently Sutherland et al tested a device called MATRx at the Royal North Shore Hospital in Sydney. What this device does, is it allows a MAS to be adjusted remotely, i.e. by a sleep technician while a patient is asleep in the sleep unit. They found that by adjusting the device overnight during a sleep study, they could actually give a good indication of whether or not the MAS would be suitable or not.

 

Why is this important? Well, if a disposable MAS could be made cheaply and used during a sleep study, we could potentially identify those patients who may be suitable for a MAS device. More importantly, we could identify those who are NOT suitable candidates for MAS. These patients otherwise need to pay for the device up front, then have a sleep study to see if it works. Hopefully, in time, patients may be able to have a trial device made, and have the sleep study to assess its effectiveness before having to spend the money to have the device made.
