Cardiogenic Shock - Heartupdate.com

Cardiogenic shock is a syndrome caused by a severe insufficiency of the heart pump manifested by the inability to provide the necessary oxygen and tissue nutrients and to remove metabolic activity product of metabolism. The main condition that leads to cardiogenic shock is the acute myocardial infarction in which necrosis is over 40% of the muscle mass of the left ventricle. In AMI, shock usually appears at 6-8 hours after the onset, but it is possible to install and after 1-2 days by extending the myocardial necrosis or by the AMI complications such as ventricular aneurysm, ventricular septal rupture (rupture of the wall that separates the two ventricles) and ventricular wall rupture. Other causes of cardiogenic shock are: diseases of the heart valves, especially aortic and mitral, intra-atrial thrombosis (formation of the clots with fairly large volume inside the atria), myocarditis, and dilated hypertrophic cardiomyopathy, arrhythmias with large increases in ventricular rate. Myocardial area affected of necrosis becomes akinetic (no more participating in heart contractions, becomes inert) and part of the myocardium that surrounds the necrosis is dyskinetic (contractions are wea Continue reading >>

    I'm something of a gadget freak... and after reading @borofergie's threads a while back about using the Ketonix Ketone Analyzer for testing ketone levels, although I thought it was quite expensive and I didn't really need one, green-eyed envy set in and I finally decided I just had to own one too! It was invented by an epileptic, Michel Lundell, who uses a ketogenic diet to control his seizures (which is an old tried and tested method used in the early 1900s!); it's made in Sweden and you can buy it directly from the Ketonix website. My main feelings about it initially were firstly the highish price, though this has now been reduced, and secondly and more importantly the fact that it apparently relied on a USB connection to a computer for power, more of which later. (They've also now introduced a more expensive Sports model which is more expensive and measures a greater ketone range - mainly at higher levels.)
    There are three different ways of measuring your ketones levels, and these also measure slightly different chemicals so they're apparently not directly comparable. (More details on the different types of measurements, plus other information, can be found on the Ketonix website. There are now also some reviews on the web where users comparison tests have been made using these three different measurements.) The first method tests beta-hydroxybutyrate in your blood which is the most accurate and also the most expensive method and this can be done with certain glucose monitors, and special - very expensive - ketone test strips, and will give you up-to-the-minute results. Some type 1 diabetics test this way, as it can also be used to check for ketoacidosis? The least reliable and cheapest test checks for acetoacetate in urine with ketone test strips such as Ketostix; this method can only give you delayed results from the surplus (if any!) ketones flushed out with your wee, but it's cheap and cheerful, if slightly messy, and is probably quite adequate if you are on a low carb diet. The Ketonix falls in the middle, both for accuracy and price, and checks the acetone levels in your breath; but its main advantage is that it's a one-off investment - there's nothing else to buy as it stands, but it relies on either a computer or something like and Amazon Kindle USB.mains plug to power it, though again see below for a solution to this issue.
    I finally decided that I'd get one after I'd read, and discovered for myself, that the waste ketones in your urine can often disappear when you are nicely in ketosis - I was sometimes having this happen, but at the same time could often "taste" them in my mouth, so I wanted some other definite and visible proof too, and it seemed a perfect justification (errm excuse ) to treat my self to this nifty little gadget. I also did a bit of research on Amazon, and found that I could buy small lightweight USB power packs complete with on/off switches, which meant that I could use the Ketonix as a free standing, completely portable unit. It arrived from Sweden within a week.
    The Ketonix itself is a small translucent tube about 6" long with a USB cable and connector permanently attached, and comes in a little drawstring bag. You blow into its mouthpiece to measure the levels of ketones in your breathe; it has a set of led "traffic lights" which light up to indicate the different ketone levels that it measures: blue for base/neutral, green for a low level, yellow for moderate, and red for a high reading. It needs to be powered up before use and this normally takes several minutes, entertaining you with flashing sequences of its led lights until it decides it's ready to go and then it sits at a steady blue. You need to blow into it gently with a normal exhaled breath for a minimum of 15 seconds for it to register. If you can keep on breathing out until your lungs are more or less empty (which can be quite hard!) you get a better indication of your ketone level, but one thing it's best not to do is to take a (deep) breath just before you blow as this means you're blowing out "fresh" air instead of nice ketone laden breath! At first I found the colours a bit misleading, as the green is rather yellowish and I mistook it for yellow, which actually is quite orange!
    I'm finding in general that if I test in the morning, I get a slightly lower result than later in the day, which tends to be somewhat higher than I'd anticipated.
    The small power pack I bought is the PowerAdd Ultra Slim from Amazon, it's not very expensive, is both very small and very lightweight, comes with a number of different colour trims, and additionally includes a selection of interchangeable connectors - only required for recharging it, and as a bonus, a plugin led light to convert it into a torch.
    My Ketonix and its matching (!! ) power pack both fit very nicely into the drawstring bag, and because of the on/off power switch I can leave the Ketonix plugged into to the power pack: all I have to do is take them out of the bag, switch on and then wait until it's stopped flashing and is ready to go.
    My completely colour co-ordinated Ketonix kit! (Alliterative too...)

    KETOSIS is a chemical /metabolic state your body is (or isn't!) in. Either your carbs are low enough for your body to be in ketosis, OR NOT. As long as you are in ketosis, your body metabolizes food differently -- it is totally irrelevant whether you are consuming "X" or "Y" number of carbs. In other words, IF you are in ketosis, it doesn't matter how deeply you are in ketosis, or how deeply purple your Ketostix are. You simply ARE or ARE NOT in ketosis.
    Eat too many carbs and your body goes out of ketosis, and changes the way it metabolizes food.
    WHILE IN KETOSIS, you cannot get all the caloric energy out of the food you eat. Fat will only give you 1 (ONE!) calorie of energy, not 9! Protein will give you only 2 calories, not 4; but carbs will still give you the full 4 calories whether or not you are in ketosis.
    So, your Ketostix turn purple because you are in ketosis and producing ketones through your now-inefficient metabolic breakdown of fat. Deeper purple is caused by more ketones, which is caused by eating more fat -- it has absolutely NOTHING to do with changing your body's "level" of ketosis. Remember, you either ARE or ARE NOT in ketosis! THERE ARE NO LEVELS OF KETOSIS, ONLY CONCENTRATIONS OF KETONES, which is entirely dependent upon how much fat you eat.
    So if you are sure you are in ketosis (which you seem to be because your Ketostix are still consistently turning even the palest shade of purple -- which can only happen if you are producing ketones which can only happen if you are in ketosis), then you can only have a limited number of problems (and it isn't ketosis!):
    1. You are simply eating TOO much, too many calories to lose weight! (and it probably is protein).
    2. You are on a plateau, and simply must wait it out.
    3. You are having a "sensitivity" issue that is causing you to retain your weight (probably water). You could be sensitive to anything: milk products, gluten, artificial sweeteners (beware maltitol), medicines, ...
    Three weeks is not an unusually long time for your weight to be stable despite your "best efforts" at losing weight. Review your daily food records and see if there is anything different about the last three weeks. Maybe you can find a clue that way.
    Note: Are you eating maltitol? LOTs of people stall by eating maltitol. "They" say maltitol has "ZERO" effective carbs; but the USDA has research that indicates that maltitol is actually worth "half" its total grams, NOT none of its grams!

    current weight: 206.0







    Are your calories too high?
    I have noticed that if my carbs are the right level and I'm in ketosis, that if I see how many calories I've eaten, I'm usually around/over 1500.
    According to Atkins, eating protein/fat is supposed to keep you full so you don't want or need to overeat. I must concur! When I overeat because it tastes so good, but I'm not hungry, I see it in the scale. For me, I've learned 1200-1300 is a good place to be, and 70% fat/30% protein is a good ratio for me (the carbs range from 20-35 when I'm losing).
    Eating after dinner also causes me to stall.

    current weight: 192.0







    Tinamarie, are you actually counting your carbs? You may be eating more carbs than you think. I understand that you can register in ketosis with up to 30 net carbs/day, maybe more, but if you're in the induction phase, you only want to be at 20. I am pretty much at that point too. Also, are you exercising. I tend to lose more weight more quickly when I don't exercise. So if you're exercising and doing everything right, just keep it up and know that doing the right thing will get you to where you want to go. I too have been in ketosis for a while and am not losing weight - I work out at least an hour a day at least 5 days/week, so I know I'm getting in better shape and that the weight loss is going slower than it has been. I just keep doing what I'm doing and I know I will reach my goals - just not by the time I had hoped.

What is INSULIN SHOCK THERAPY? What does INSULIN SHOCK THERAPY mean? INSULIN SHOCK THERAPY meaning - INSULIN SHOCK THERAPY definition - INSULIN SHOCK THERAPY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Insulin shock therapy or insulin coma therapy (ICT) was a form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks. It was introduced in 1927 by Austrian-American psychiatrist Manfred Sakel and used extensively in the 1940s and 1950s, mainly for schizophrenia, before falling out of favour and being replaced by neuroleptic drugs in the 1960s. It was one of a number of physical treatments introduced into psychiatry in the first four decades of the twentieth century. These included the convulsive therapies (cardiazol/metrazol therapy and electroconvulsive therapy), deep sleep therapy and psychosurgery. Insulin coma therapy and the convulsive therapies are collectively known as the shock therapies. Insulin coma therapy was a labour-intensive treatment that required trained staff and a special unit. Patients, who were almost invaria

2 Pathophysiology Of Acute Hemorrhagic Shock

Pathophysiology of Acute Hemorrhagic Shock A variety of definitions of hemorrhagic shock have arisen as more understanding of the mechanisms involved have been developed. Several definitions could be considered to be archaic but in general remain accurate (see Box 2-1 ). A modern definition of shock would acknowledge first that shock is inadequate tissue perfusion and inadequate removal of cellular waste products and second that shock is a failure of oxidative metabolism that can involve defects of oxygen (1) delivery, (2) transport, or (3) utilization, or combinations of all three. The diagnoses of clinical signs of shock are primarily related to organ failure, but organ failure is secondary to failure of the cells. Shock is used in reflections drawn from experiences with gunshot wounds. "Shock is the manifestation of the rude unhinging of the machinery of life." Many authors have described the "vicious cycles" in shock (see Figure 2-1 ). They may cascade in a variety of ways such as decreased cardiac output, which leads to a decreased blood pressure, which in turn leads to decreased tissue per- Suggested Citation:"2 Pathophysiology of Acute Hemorrhagic Shock."
