Regulating Arterial Blood Pressure
One of the things that we know about hypertension is, first of all, it affects one out of every three adults. It's an epidemic in our country and it's one of the major concerns for institutes like NIH and the American Heart Association. It's primarily two disease models. Hypertension, which is higher blood pressure. And lower blood pressure, which is orthostatic intolerance. For someone who has really low blood pressure, they may have trouble standing up with this. So with the micronography technique we're taking a tungsten microelectrode and we're inserting it into the peroneal nerve.
And this right now is the gold standard for assessing sympathetic traffic. It's the only method out there where we can get direct signals of sympathetic traffic. When we're probing for a sympathetic nerve we're listening for what we call an insertion burst. That insertion burst will give us an indication that we're actually in the nerve. Now we still have to make tiny microadjustments sometimes in order to get there because we're actually recording from multiple fibers. And what we're interested in is, individuals who are more prone to fainting have lower.
Sympathetic tone, lower sympathetic traffic, and, or, they have a reduced ability to increase sympathetic traffic. So on one scale, one side of the spectrum we're looking at fainting and orthostatic intolerance. On the other side of the scale, someone who has a high sympathetic traffic, outflow, and tone, often is associated with hypertension. And so we look at these patients and try to characterize their activity levels, and then we expose them to various types of intervention. So one intervention is getting more sleep, other interventions are physical activity. One that we just completed was looking at the effects of the Omega3 fatty acids,.
What Is Blood Pressure hypotension hypertension systolic diastolic pressure
Hi i m sami from fawzi academy In this tutorial I will generally talk about blood pressure Blood pressure BP is the pressure exerted by circulating blood upon the walls of blood vessels and is one of the principal vital signs. blood pressure usually refers to the arterial pressure of the systemic circulation, usually measured at a person's upper arm. A person's blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury mm Hg. Normal resting blood pressure for an adult is approximately 12080 mm Hg.
Blood pressure varies depending on situation, activity, and disease states, and is regulated by the nervous and endocrine systems. Blood pressure that is pathologically low is called hypotension, and pressure that is pathologically high is hypertension. Both have many causes and can range from mild to severe, with both acute and chronic forms. Chronic hypertension is a risk factor for many complications, including peripheral vascular disease, heart attack, and stroke. Hypertension is generally more common, also due to the demands of modern lifestyles. Hypertension and hypotension go often undetected because of infrequent monitoring.
FOX 9 features Twin Cities womans struggle with POTS condition
Voiceover And now, FOX 9 News at 9. February, just around the corner, is American Heart Month. Tonight we're focusing on heart health. Often we think of heart attacks or stokes on this subject. But there are many other diseases and disorders that affect the heart. Many are mysterious in nature and in need of research. Voiceover Take a look at 32 year old Elle Kirchoff. At first glance, you'd never guess that she has to spend most of her time in a wheelchair. Voiceover So you can't stand for long periods of time.
No. On a good day I can walk from my reclining chair to my kitchen sink, that's about it. On a bad day, I can maybe make it half way. Then I'm on the floor. Doctors know what's wrong with her they're just not sure yet how to fix it. It's called POTS, or POTS and that's short for a longer medical term. Basically she stands up, her heart starts racing, her brain says to slow down and then her blood pressure plummets and she passes out. This is something that has gotten worse with time.
Voiceover You were passing out quite a bit. Yeah, I passed out 3 to 4 times a day. Voiceover Still Still, yeah. During the good phase of my life I would pass out maybe once or twice a week. In about 2011 is when it became a real problem because I was passing out daily, several times a day, again. Voiceover POTS forced her to give up her job as a high school Spanish teacher. Voiceover This is my second year teaching there, so it was in 2006.
Voiceover And quite honestly, threw her future into uncertainty. Her search for help took them to MAYO Clinic. The MAYO Clinic has a clinic on this but POTS typically affects teenage girls going through puberty. Most of them outgrow it. Elle has a rare form of something that's already pretty uncommon. Elle's case may have started with a 15 pound tumor that was removed when she was in high school, throwing her whole system out of whack. My future is why. Voiceover And what she desperately needs is research which is why the.
American Heart Association of Minnesota chose her to be a spokeswoman of sorts. The American Heart Association has been fabulous because they've given me a voice. Nobody's heard of POTS. What I want, is some researcher out there or some physician to get an interest and say This needs to be looked into, something needs to be done for all these people who are left disabled. Voiceover And this young, vibrant, 32 yearold is engaged. But holding off on tying the knot with that hope that medical science will come through.
Ellen discusses POTS condition and heart health with KARE 11s Diana Pierce
Energetic music Well, tommorow, as part of Go Red Day, there is a free women's health expo at the Mall of America from 11 a.m. to 4 p.m., and joining us right now is Ellen Kirchoff, 2015 Twin Cities Go Red for Women casting call winner spokesman for the American Heart Association, that's a mouthful. Thank you so much for joining us. Thank you for having me, Diana. Now tell us about your journey to become the casting call winner. All right, so last year I heard about the.
Casting call, and I knew I had to go. For me, it's really important to get involved with the American Heart Association because it took me a long time to find my own diagnosis, and I've actually been battling heartrelated illness for 13 years now, and so the fact that I just got my diagnosis two years ago, I don't want that to have to happen to every woman, and so for me, working with the American Heart Association, I wanna spread my story but also get other women involved in their own health and get them to realize.
That their health is just as important as their husbands' or their kids'. Oh, tell us about your specific diagnosis. So, I have POTS, or postural orthostatic tachycardia syndrome, and basically what that means is when I change posture or stand up, my heart goes into tachycardia. It speeds up really fast, but what happens in my body is my blood pressure then plummets and drops, causing me to actually lose consciousness, and so when I do stand up, or when I stand for long periods of time, I pass out, and I then wake up on the floor.
And it all started when I was 18. I had a 15pound paraovarian cyst on one of my ovaries, and when it got removed, my whole autonomic system kinda got thrown into a funk, and so my body never recovered. And part of the issue of the recovery is that my heart and my brain, they're just not friends. And so they don't communicate properly, which leads to the tachycardia and the blood pressure dropping. And basically, when you say tachycardia, basically, and you just explained this to me before we went into the break, is that the chamber.
Of your heart doesn't completely fill up with blood. Right, so then I don't get enough oxygen to my brain, and so sometimes right before I pass out, I'll kind of stumble or I'll get really sick to my stomach, and then down I go. And friends and family have been watching this for years, and I'm sure that they were just fearful for you. You know, it's funny because to me, my journey isn't that difficult. It's hard, but it hasn't been that difficult. But everybody who sees me pass out.
All the time and have seen the injuries and have watched it progress, that's been really difficult for them, and that hurts me because then I feel bad. Let's talk about tomorrow, what's happening tomorrow You're in a fashion show. Yes, so tomorrow at the Mall of America, there's gonna be a fashion show. There's gonna be lots of heart healthrelated events and things to do, and just come on out. Bring the family, and let's empower women and empower women's health. So it'll be great, there's a fashion show,.
There's the casting call, which I did last year and won, and there's just a bunch of different stuff. And with Macy's this year, they're selling the red dresses, and then also the shirt that I have on, and 100 of the proceeds from this shirt actually goes back to the American Heart Association. All right, we're gonna leave it right there. Thank you so much for joining us. We really appreciate it, congratulations on your win, and good luck tomorrow. Ellen 'preciate it. Diana Again, for more.
