nih on flow limitation

Interesting article, however, the source is misrepresented. It is an article from Sleep Science the journal of the Brazilian Sleep Association, It is accessed through PUB MED which is an NIH funded search engine and journal access web site.

Noting that the article is from 2015 so it's not new information. It would help if you make it clear that this is your interpretation of the article, not a summary from NIH which is implied.

Also, as a side note, does this mean you are going to quit haring on how in-home studies are going to replace in-lab testing in a year or so?

From the Journal article:

9. Conclusion
Categorizing SDB using measures related only to reduction in airflow does not encompass the range of upper airway abnormalities, and further categorization of the full spectrum of abnormalities is needed. While many tools are available for determining respiratory effort and airflow, measurement of nasal flow by a nasal cannula pressure transducer permits recording of the respiratory flow curve. The flow tracing generated has a consistent relationship with upper airway resistance; and therefore can help assess for pathological IFL when used in conjunction with other variables, such as EEG tracing and tcCO2, in patients with mild SDB.

Analysis of multiple indices for quantifying recorded SDB has shown that scoring flow limitation events in addition to apneas and hypopneas has a better sensitivity and specificity of correlating symptoms with their respiratory causes than currently used strategies. In particular, it is necessary to detect more subtle forms of SDB such as IFL in certain patient populations that do not present with frank apneas. Standardized IFL scoring should lead to better detection and characterization of IFL. A reasonable threshold to define abnormal IFL would be greater than 30% of sleep, however other quantifiable techniques should be considered. While there is data that IFL may be linked to clinical consequences in certain circumstances, more research is needed to establish guidelines in reproducible scoring of IFL. In addition, further evidence of its negative health associations are warranted before routinely incorporating into PSG interpretation.

There is no summary, so when you wrote:

SUMMARY
THE CURRENT CRITERIA USING AHI IS WRONG
RDI is better and RERAs are important in SDB

titration to eliminate FL results in better outcomes than merely eliminating apnea


That is your opinion, it is not as claimed from the article.

As far as the ASST opinion on IHT vrs lab test, you have repeated it ad nausium, and this Journal article disputes the advisability of that conclusion, so which is it? You have now claimed both.

Last I checked, a summary is your opinion of what the article says.

Care to address your misrepresentation of the source of the information? Care to clearly and cogently state how you have decided I am one of the dumber libtards? How about clarifying how it is you claim to attack when attacked but attack me for pointing out the obvious errors in your posts? Am I correct in believing that any corrections to your posts are interpreted as an attack on you?

Claiming that an article from the Jurnal of the Brazilian Sleep Medicine Society is the opinion of the National Institutes of Health is not a misrepresentation? Writing your summary in bold after several limes of cut and paste so that your summary appears to represent the conclusions of the authors is not a misrepresentation? My being able to read the article, and link it past claims quoted serially repeated by you makes me a "dumb libtard". Calling your misrepresentations and outright fabrications and mistakes makes me a "dumb libtard"?

I am so confused, maybe I am a dumb libtard, but I will continue to note your errors in reading comprehension, medical understanding, attributions, and anything else where you denigrate forum posters who you falsely accused of doing exactly what you do.

I have on many occasions pointed out more substantial mistakes on your part, you just call me names. So you lay your games and I will point out your errors. You will call me names without ever correcting your errors or acknowledging them. Suit yourself

Maybe so, but would you like to tell us more about pulmonary hypertension? You were so wrong on that someone could get killed listening to you.

Oh, by the way, notice I am not doing any name calling or bullying only you are doing that.

To all appearances, you care. I care that makes 2 of us. And no you are not correct on pulmonary hypertension. HEre is from one of your favored resources, Mayo Clinic. You will no doubt notice there is nothing at all about elevated systemic high blood pressure mentioned. Imagine, all this verbiage, and not a work about HBP.

Pulmonary hypertension

Diagnosis
Pulmonary hypertension is hard to diagnose early because it's not often detected in a routine physical exam. Even when the condition is more advanced, its signs and symptoms are similar to those of other heart and lung conditions.
To diagnose your condition, your doctor may review your medical and family history, discuss your signs and symptoms, and conduct a physical examination. Doctors may order several tests to diagnose pulmonary hypertension, determine the severity of your condition and find out the cause of your condition. Tests may include:

Echocardiogram. Sound waves can create moving images of the beating heart. An echocardiogram can help your doctor to check the size and functioning of the right ventricle, and the thickness of the right ventricle's wall. An echocardiogram can also show how well your heart chambers and valves are working. Doctors may also use this to measure the pressure in your pulmonary arteries.
In some cases, your doctor will recommend an exercise echocardiogram to help determine how well your heart and lungs work under stress. In this test, you'll have an echocardiogram before exercising on a stationary bike or treadmill and another test immediately afterward. This could be done as an oxygen consumption test, in which you may have to wear a mask that assesses the ability of your heart and lungs to deal with oxygen and carbon dioxide.
Other exercise tests may also be done. These tests can help determine the severity and cause of your condition. They may also be done at follow-up appointments to check that your treatments are working.
Chest X-ray. A chest X-ray can show images of your heart, lungs and chest. This test can show enlargement of the right ventricle of the heart or the pulmonary arteries, which can occur in pulmonary hypertension. This test can also be used to identify other conditions that may be causing pulmonary hypertension.
Electrocardiogram (ECG). This noninvasive test shows your heart's electrical patterns and can detect abnormal rhythms. Doctors may also be able to see signs of right ventricle enlargement or strain.
Right heart catheterization. After you've had an echocardiogram, if your doctor thinks you have pulmonary hypertension, you'll likely have a right heart catheterization. This test can often help confirm that you have pulmonary hypertension and determine the severity of your condition.
During the procedure, a cardiologist places a thin, flexible tube (catheter) into a vein in your neck or groin. The catheter is then threaded into your right ventricle and pulmonary artery.
Right heart catheterization allows your doctor to directly measure the pressure in the main pulmonary arteries and right ventricle. It's also used to see what effect different medications may have on your pulmonary hypertension.
Blood tests. Your doctor might order blood tests to check for certain substances in your blood that might show you have pulmonary hypertension or its complications. Blood tests can also test for certain conditions that may be causing your condition.
Your doctor might order additional tests to check the condition of your lungs and pulmonary arteries and to determine the cause of your condition, including:
Computerized tomography (CT) scan. During a CT scan, you lie on a table inside a doughnut-shaped machine. CT scanning generates X-rays to produce cross-sectional images of your body. Doctors may inject a dye into your blood vessels that helps your arteries to be more visible on the CT pictures (CT angiography).
Doctors may use this test to look at the heart's size and function and to check for blood clots in the lungs' arteries.
Magnetic resonance imaging (MRI). This test may be used to check the right ventricle's function and the blood flow in the lung's arteries. In this test, you lie on a movable table that slides into the tunnel. An MRI uses a magnetic field and pulses of radio wave energy to make pictures of the body.
Pulmonary function test. This noninvasive test measures how much air your lungs can hold, and the airflow in and out of your lungs. During the test, you'll blow into a simple instrument called a spirometer.
Polysomnogram. This test detects your brain activity, heart rate, blood pressure, oxygen levels and other factors while you sleep. It can help diagnose a sleep disorder such as obstructive sleep apnea.
Ventilation/perfusion (V/Q) scan. In this test, a tracer is injected into a vein in your arm. The tracer maps blood flow and air to your lungs. This test can be used to determine whether blood clots are causing symptoms of pulmonary hypertension.
Open-lung biopsy. Rarely, a doctor might recommend an open-lung biopsy. An open-lung biopsy is a type of surgery in which a small sample of tissue is removed from your lungs under general anesthesia to check for a possible secondary cause of pulmonary hypertension.

Or, alternatively, proof that not only are you wrong on this, you are dangerously wrong.

JUst keep attacking when proven wrong. Guess when you have no facts supporting you, namecalling is all you have.

The only thing I have done is to point out where you are wrong and pointed out your repeated claims that you are never wrong, now changed to never wrong on anything substantial. You name call and denigrate. You claim to be defending, what is it you are defending? Your Honor?

I take my meds daily, as prescribed. What is your excuse? And denying you are wrong when you are wrong does not change the fact that you are wrong, and you are wrong on more than insignificant details. But its obvious I am not going to change your mind about infallibility, so I will just continue to note errors when you make them, pray you get no one hurt, and live being accused of being a bully from the biggest bully on this site.

The truth is apearent - you sure do not need an excuse but there must be some reason for all the shouting and name calling? My behavior is decidedly not anti-social - I keep on addressing you don't I?

OH yeah, recall when you claimed that the administrators had told me to knock it off. They didn't, and they haven't. I'd suggest you report me if you do not care for me correcting your misstatements and misleading information.

Well now you admit you do make errors, so your frequent statements that you never are wrong are proven in error. What lie are you claiming I have made?

liar liar panties on fire

Seriously? What are you? 6 years old?

This entire thread TASmart has been civil and respectful. You are acting like a spoiled brat. And you lack the insight to see that.

I correct inaccuracies, and I challenge xxyzx to show one lie in any post I made.
