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.

Obesity, Sleep Apnoea, and Heart Surgery

Filed under: Blog — Tags: , , , , , , , , — Mark Russell-Pavier @ 1:25 am

A study recently published in Chest investigated obesity, sleep disordered breathing and complications after cardiac surgery. Atrial fibrillation, the complication being investigated, is an abnormal heart rhythm characterised by rapid and irregular beating; a disruption in the electrical system of your heart.

The study took large group of 190 people. Each person had done a sleep study, and then had cardiac surgery within three years. The investigation aimed to use that data to determine whether sleep apnoea is a risk factor for post-cardiac surgery atrial fibrillation. Whilst the study concluded that there was no association between the two, the methodology may be flawed.

The study took the AHI of the patients, and adjusted it for obesity, and then compared that to atrial fibrillation numbers. By doing this they may have eliminated a great deal of the variation in AHI, thereby making it difficult to form a statistical association. Perhaps a better way of investigating the relationship would be to split the group of patients into three; one with sleep apnoea and no obesity, one with obesity, and one with sleep apnoea and obesity. The difference between the three groups might have investigated the relationship more conclusively.
