You can use inexpensive methods for sleep apnea testing, in your own house, without the need to go to the sleep lab. These tests don't show as much as a polysomnogram test, so if you have the possibility to take a sleep study, please don't hesitate.
However, if you know what to look for, a cheap but clever test can help you a great deal to diagnose sleep apnea. At least, it's a start.
Keep in mind that sometimes a sleep disorder doesn't come alone.
Many people can't afford a sleep study in a sleep center. But they still want to find out how good is their sleep. Using a mobile app can be the cheapest way to check your sleep.
The most simple method will be to use an iPhone, iPad or Android application that can record your sleep and show you the sleep graphic in the morning.
These apps can help you discover if you snored during sleep, how loud and when exactly did you snore. All the data is recorded and displayed graphically on the mobile device.
The SnoreLab not only records, measures and tracks your snoring but it can also recommend ways to reduce it and then test how effective are those remedies.
You'll also get a snore score that indicates how severe is your snoring. This info useful for sleep apnea sufferers.
Using SnoreLab while you try the positional therapy for sleep apnea is an excellent idea, because you'll now know if sleeping on the side can make a difference in your sleep.
If you don't have a smartphone, I can still help you with a solution.
The following steps clearly explains the Audacity Sleep apnea Testing:
You will need an audio device which can record your sleep sounds for many hours. You will need data for at least 2 hours of sleep.
This audio recorder should have a USB connection (or other types) for your computer, to upload the mp3 file.
RCA VR5220 512 MB Digital Voice Recorder (Black) is a a great recorder for the 29 dollars spent. It's simple to use and is also compatible with Mac.
If you want the best recorder, then Olympus LS-10 Linear PCM Recorder can be what are you looking for, but I don't think you need the best gadget in world to record your sleep apnea events.
The next morning, connect your mp3 recorder to your computer and upload the file. You can listen to the sound of your sleep, to find if you have a loud and irregular snoring, or your stop breathing in sleep.
But you are very busy and you don't have time to listen all that noise. So, I recommend to use an audio software where you can see and analyze your mp3 file.
Fortunately, there is a free software to use, free MP3 manipulating program called Audacity. Just download the program and install it to your computer.
Once into Audacity, hit:
You can easily see each breath (or snore) displayed in the graphical Audacity form, by clicking on the magnify (+) key a couple of times.
If you have a normal sleep pattern, your graphic detail should look consistent throughout the entire recording. However, if you stop breathing in sleep, then...you will see unusually long gaps between breaths.
If you find a long gasp in your graph, select the beginning of it and hit play. You will hear nothing, then a snort or a gasp for air, and snoring.
This is an obstructive sleep apnea event.
