You have sleep apneawhat now
Typically what we will do after you're diagnosedwith sleep apnea is we'll bring you back for a titration study. And basically what thatdoes is those are done in the lab and our technicians or respiratory therapists willactually measure you to determine what size of mask that you need and what type of maskthat you are most comfortable with because there are multiple types. There's a type thatcovers the nose and the mouth and a and a type that covers just the nose. And withinthe types that cover the nose, there's ones that sits over the nose like a dome as wellas ones that go up in the nose almost like thick oxygen prongs. And so typically whenwe bring you back for your titration we determine
which feels most comfortable to you and thenwhat we do is we start with a low airway pressure through the machine and we continue to monitoryou to see if you have sleep apnea. If you're demonstrating sleep apnea through your studythen we continue to increase your pressure until we see those events go away and that'stypically then around the pressure that we'll prescribe for you to start using at home.But even after that you need to have regular followups with your sleep physician becauseadjustments are typically needed to optimize things. This is because sometimes people sleepa little bit differently at home then they do in the laboratory. It really depends onthe severity, in my experience, of their sleep
apnea. Typically what I see is the more severesomebody's sleep apnea, the more they notice a difference more quickly. And I've had patientsthat have said they've slept the best night of their life that they've slept in the lasttwenty years after just one night of using their CPAP. But as we know, sleep deprivationis not something that goes away overnight. And so if somebody has had significant sleepapnea and been sleep deprived from it for years, typically it can take weeks to monthsuntil somebody really starts feeling their optimum. It's important that if you're diagnosedwith obstructive sleep apnea or central sleep apnea that you do get treated because we knowthat patients that go for a long period of
time years to decades without being treateddo have an increased risk of early strokes, heart disease, those types of things. There'salso now been shown some linkages to difficulty in controlling things like blood sugar, yourblood pressure and those types of things in patients that have significant sleep apneaand aren't being treated.
Sleep apnea research The HeartBEAT Study Susan Redline
I'm Susan Redline. I'm from Harvard Medical School and I lead the HeartBEAT study. And HeartBEAT stands for Heart Biomarkers in Apnea Treatment Study. And what this study is is the first ever controlled, randomized study comparing treatment outcomes in patients with sleep apnea. And very specifically we've identified using prior research that sleep apnea and heart disease are highly correlated. And it appears that sleep apnea increases your risk for heart disease. What we didn't know before the study
is whether treatment of sleep apnea might reduce your heart disease risk factors. And furthermore we also didn't know what might be the best treatment. Because of the funding opportunity we were able to for the very first time move our questions out of a typical sleep laboratory, where we know patients have sleep disorders, into cardiology practices, and pilot and refine an approach for screening and diagnosing new cases of sleep apnea and heart disease.
Already we analyzed our crosssectional data and we saw for example that sleep apnicsâ€” that the severity of sleep apnea correlated or was associated with how high your blood pressure went up at night during sleep. So one of the things we are going to be looking for is whether treatment with CPAP or with oxygen reduces not only your daytime blood pressure but your average blood pressure over a 24hour period, including that period at night when many heart attacks and strokes occur.
