As I began to look at the on-line news in the very ‘wee hours’ of this morning, The headline of a CBC Radio Canada article soon caught by eye: “Millions of people in Canada have sleep apnea. The problem is not all of them realize it.”

Indeed, “not all of them” was putting it mildly, when that was followed by this sub-heading: “Roughly 8 out (of) 10 with sleep apnea are undiagnosed.”

The article cites a 2014 study by Canadian medical experts. They cited information gathered by Statistics Canada indicating an estimated 5.4 Million Canadian adults had been diagnosed with sleep apnea or were at high risk of experiencing obstructive sleep apnea.

Sleep apnea is a condition in which breathing stops and restarts often many times during sleep. When that happens the heart has to work harder to keep pumping vital oxygen-rich blood to the body. Over time that can lead to heart problems. Meanwhile, there’s always the risk a person with sleep apneal won’t start breathing again.

So, if someone says, or perhaps complains, you snore and gasp in your sleep, you may want to consider seeking medical advice; or also, if you experience other symptoms of poor quality, or lack of sleep, like excessive tiredness and lack of energy during the day. The latter has become the story of my life in the past year as I struggle, so far unsuccessfully, to master the art of using what the CBC article calls the “first-line, gold-standard” treatment for sleep apnea, the CPAP machine

More about that in a moment; but first, the basics. The U.S. National Library of Medicine has one of the best, brief descriptions of the two types of sleep apnea, obstructive sleep apnea (OSA), and central sleep apnea. OSA “happens when your upper airway becomes blocked many times while you sleep, reducing or completely stopping airflow. This is the most common type of sleep apnea. Anything that could narrow your airway such as obesity, large tonsils, or changes in your hormone levels can increase your risk for obstructive sleep apnea. Central sleep apnea happens when your brain does not send the signals needed to breathe. Health conditions that affect how your brain controls your airway and chest muscles can cause central sleep apnea.”

I get the impression central sleep apnea is a relatively new area of study, but to be honest I don’t know, and maybe my memory has failed me on this point; but I don’t recall ever being told which type of sleep apnea I have, despite having had three overnight sleep lab tests, all of them in Owen Sound. The last one was mid-October, 2023. So far there are no results, and no telling how long I will wait to hear from a specialist to discuss them. I waited a year after my second overnight test about five years ago. I take that to be a measure of the level of demand. When I had my first test, the technician told me I woke up briefly 40 times because I had stopped breathing, but I had no memory of that happening. Fortunately, my brain took charge and pushed the figurative ‘restart’ button. And that was called “mild, to moderate” sleep apnea.

After the second sleep test, I was prescribed to go on a CPAP (continuous positive airway pressure) machine, after a trial run of a week when it seemed to work for me. With a constant level of measured, pressurized air going from the machine to your airway, the system is designed to take keep you breathing if you stop. And you will, that is a given with sleep apnea.

But, despite the encouraging start, there was a problem, though the machine itself was working properly when tested. I tried different remedies, including going from a nasal to a full mask (nose and mouth) and still the problem continued: waking up after an hour or two with a very dry mouth and throat.

Turns out this problem, getting used to the CPAP machine, is not unusual: Forty percent or more of people who start, give up on it; but that should not be an option.

I confess I gave up for a while, but, realizing the risk I was taking, tried again, and again. And I’m still trying, as my sleep quality has continued to worsen. Recently, I bought an oximeter device, as a kind of ‘back up’ just in case. Made to fit like a ring on suitable finger, the device keeps track of blood-oxygen level and heart pulse. One of the risks of sleep apnea is that the heart has to work harder to keep pumping oxygenated blood when breathing stops. If the blood-oxygen level goes below a set percentage – I’ve set mine at 92 percent – the device has a vibration-alarm that is supposed to ‘gently’ alert you to restart breathing, but not necessarily wake you up. I’ve got the alarm set a ‘very strong’ but still it doesn’t consciously wake me up. Fair to say, I think, it’s not a good idea for the hard of hearing. So, time to get hearing aids after all, I guess, ASAP.

The ring-device comes with a smart phone or computer app which, when connected to the device shows the ups and downs of your blood-oxygen and heart pulse. That has been interesting and eye-opening, especially when the blood-oxygen level has gone below 90, before recovering, which has happened a few times. That’s troubling, but better to know than not.

To summarize, my sleep apnea has recently become life-changing: tired during the day, while trying to catch up by napping one or more times; and worst of all, lack of energy, having to push myself to get doing what came so easily even up to a year ago.

That’s not the way I want to live; but I am determined to find a way to overcome this sleep apnea challenge. And when that happens, I’ll be sure to let you know.
