Respiratory acidosis #sign and symptoms of Respiratory acidosis Respiratory acidosis ABGs Analyse https://youtu.be/L5MWy1iHacI Plz share n subscribe my chanel is a condition that occurs when the lungs cant remove enough of the Suctioning https://youtu.be/hMJGkxvXTW0 carbon dioxide (CO2) produced by the body. Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. Normally, the body is able to balance the ions that control acidity. This balance is measured on a pH scale from 0 to 14. Acidosis occurs when the pH of the blood falls below 7.35 (normal blood pH is between 7.35 and 7.45).Rinku Chaudhary NSG officer AMU ALIGARH https://www.facebook.com/rinkutch/ Respiratory acidosis is typically caused by an underlying disease or condition. This is also called respiratory failure or ventilatory failure. Suctioning https://youtu.be/hMJGkxvXTW0 Normally, the lungs take in oxygen and exhale CO2. Oxygen passes from the lungs into the blood. CO2 passes from the blood into the lungs. However, sometimes the lungs cant remove enough CO2. This may be due to a decrease in respiratory rate or decrease in air movement due to an underlying condition such as: asthma COPD pneumonia sleep apnea TYPES Forms of respiratory acidosis There are two forms of respiratory acidosis: acute and chronic. Acute respiratory acidosis occurs quickly. Its a medical emergency. Left untreated, symptoms will get progressively worse. It can become life-threatening. Chronic respiratory acidosis develops over time. It doesnt cause symptoms. Instead, the body adapts to the increased acidity. For example, the kidneys produce more bicarbonate to help maintain balance. Chronic respiratory acidosis may not cause symptoms. Developing another illness may cause chronic respiratory acidosis to worsen and become acute respiratory acidosis. SYMPTOMS Symptoms of respiratory acidosis Initial signs of acute respiratory acidosis include: headache anxiety blurred vision restlessness confusion Without treatment, other symptoms may occur. These include: https://www.healthline.com/health/res... sleepiness or fatigue lethargy delirium or confusion shortness of breath coma The chronic form of respiratory acidosis doesnt typically cause any noticeable symptoms. Signs are subtle and nonspecific and may include: memory loss sleep disturbances personality changes CAUSES Common causes of respiratory acidosis The lungs and the kidneys are the major organs that help regulate your bloods pH. The lungs remove acid by exhaling CO2, and the kidneys excrete acids through the urine. The kidneys also regulate your bloods concentration of bicarbonate (a base). Respiratory acidosis is usually caused by a lung disease or condition that affects normal breathing or impairs the lungs ability to remove CO2. Some common causes of the chronic form are: asthma chronic obstructive pulmonary disease (COPD) acute pulmonary edema severe obesity (which can interfere with expansion of the lungs) neuromuscular disorders (such as multiple sclerosis or muscular dystrophy) scoliosis Some common causes of the acute form are: lung disorders (COPD, emphysema, asthma, pneumonia) conditions that affect the rate of breathing muscle weakness that affects breathing or taking a deep breath obstructed airways (due to choking or other causes) sedative overdose cardiac arrest DIAGNOSIS How is respiratory acidosis diagnosed? The goal of diagnostic tests for respiratory acidosis is to look for any pH imbalance, to determine the severity of the imbalance, and to determine the condition causing the imbalance. Several tools can help doctors diagnose respiratory acidosis. Blood gas measurement Blood gas is a series of tests used to measure oxygen and CO2 in the blood. A healthcare provider will take a sample of blood from your artery. High levels of CO2 can indicate acidosis.

Metabolic Acidosis: Causes, Symptoms, And Treatment

The Terrible Effects of Acid Acid corrosion is a well-known fact. Acid rain can peel the paint off of a car. Acidifying ocean water bleaches and destroys coral reefs. Acid can burn a giant hole through metal. It can also burn holes, called cavities, into your teeth. I think I've made my point. Acid, regardless of where it's at, is going to hurt. And when your body is full of acid, then it's going to destroy your fragile, soft, internal organs even more quickly than it can destroy your bony teeth and chunks of thick metal. What Is Metabolic Acidosis? The condition that fills your body with proportionately too much acid is known as metabolic acidosis. Metabolic acidosis refers to a physiological state characterized by an increase in the amount of acid produced or ingested by the body, the decreased renal excretion of acid, or bicarbonate loss from the body. Metabolism is a word that refers to a set of biochemical processes within your body that produce energy and sustain life. If these processes go haywire, due to disease, then they can cause an excess production of hydrogen (H+) ions. These ions are acidic, and therefore the level of acidity in your body increases, leading to acidem Continue reading >>

    I don't have full access to this study. I wonder what sort of breakfast they had. I also wonder if these people are in ketosis, if they weren't the huge increase in ketones might be insignificant.
    Basically for four hours:
    1 cup of coffee= 88% increase in ketone production. 2 cups of coffee= 116% increase in ketone production.
    I always feel much worse after drinking caffeine.

    Interesting, but I don't think there's much benefit to chasing ketone production, with regard to nutritional ketosis. Producing more or less ketones doesn't mean a whole lot on its own, they exist to provide energy and your body will dump the excess it doesn't need.
    It certainly may explain increased mental energy in ketosis after having a cup of coffee, if there's both more ketones and the effects of caffeine.

  3. Because_Science_Bro

    I know this is a week after this was posted & didn't seem to gain much interest but I figured that I would share some of the main points from the article for those who don't have access:

    Total of ten subjects (2 men + 8 women)

    Subjects had to refrain from caffeine consumption for 24 hours and be fasted for 12 hours prior to each of the three study days. The three study days involved one with no caffeine (baseline), and two different days with different doses of caffeine.

    Subjects received a "standard breakfast" for each testing day that included two pieces of toast with raspberry jam, a piece of cheese, 104 mL applesauce, and 100 mL juice.

    Breakfast macros: 85 g carbs, 9.5 g fat, 14 g protein

    Caffeine pills were crushed and added to the applesauce and given in different doses on different test days to be equivalent to either 1 1/2 cups coffee or 3 cups coffee.

    Blood was collected every 30 minutes during 4 hour period then spun down to collect plasma, which was analyzed for caffeine, acetoacetate, β-hydroxybutyrate, and free fatty acids.
    To answer your question, no these individuals are not in ketosis nor are they given anything resembling a ketogenic breakfast. At first this article really bugged me. It's super simplistic and doesn't seem to be terribly well-done, which is why it is in a super low impact journal; however, I think it does have merit upon a little reflection. There are some really interesting clinical drugs that have been conducted and are currently underway to help Alzheimer's patients achieve ketosis via pharmaceutical intervention without having to modify their existing diet. On the surface that seems really obnoxious because why not just have them eat a ketogenic diet instead of turning it into a pill, which obviously would be the simplest and most straight forward way, but diet compliance in the elderly population can be difficult and it would be really difficult to try to convince caretakers to shift AD patients to a keto diet. So this study does hold some value that a high carb breakfast with caffeine pills does increase production of beta-hydroxybutyrate... whether those levels are actually beneficial long-term in the form of nutritional ketosis or how much the brain would even utilize them in the presence of so much glucose remains unclear.

What is ALKALOSIS? What does ALKALOSIS mean? ALKALOSIS meaning - ALKALOSIS pronunciation - ALKALOSIS definition - ALKALOSIS explanation - How to pronounce ALKALOSIS? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6Uu... Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma (alkalemia). In contrast to acidemia (serum pH 7.35 or lower), alkalemia occurs when the serum pH is higher than normal (7.45 or higher). Alkalosis is usually divided into the categories of respiratory alkalosis and metabolic alkalosis or a combined respiratory/metabolic alkalosis. Respiratory alkalosis is caused by hyperventilation, resulting in a loss of carbon dioxide. Compensatory mechanisms for this would include increased dissociation of the carbonic acid buffering intermediate into hydrogen ions, and the related excretion of bicarbonate, both of which lower blood pH. Hyperventilation-induced alkalosis can be seen in several deadly central nervous system diseases such as strokes or Rett syndrome. Metabolic alkalosis can be caused by repeated vomiting, resulting in a loss of hydrochloric acid within the stomach content. Severe dehydration, and the consumption of alkali are other causes. It can also be caused by administration of diuretics and endocrine disorders such as Cushing's syndrome. Compensatory mechanism for metabolic alkalosis involve slowed breathing by the lungs to increase serum carbon dioxide, a condition leaning toward respiratory acidosis. As respiratory acidosis often accompanies the compensation for metabolic alkalosis, and vice versa, a delicate balance is created between these two conditions. Metabolic alkalosis is usually accompanied by low blood potassium concentration, causing, e.g., muscular weakness, muscle pain, and muscle cramps (from disturbed function of the skeletal muscles), and muscle spasms (from disturbed function of smooth muscles). It may also cause low blood calcium concentration. As the blood pH increases, blood transport proteins, such as albumin, become more ionized into anions. This causes the free calcium present in blood to bind more strongly with albumin. If severe, it may cause tetany.

Chapter 47. Acidosis And Alkalosis

Systemic arterial pH is maintained between 7.35 and 7.45 by extracellular and intracellular chemical buffering together with respiratory and renal regulatory mechanisms. The control of arterial CO2 tension (Paco2) by the central nervous system (CNS) and respiratory systems and the control of the plasma bicarbonate by the kidneys stabilize the arterial pH by excretion or retention of acid or alkali. The metabolic and respiratory components that regulate systemic pH are described by the Henderson-Hasselbalch equation: Under most circumstances, CO2 production and excretion are matched, and the usual steady-state Paco2 is maintained at 40 mmHg. Underexcretion of CO2 produces hypercapnia, and overexcretion causes hypocapnia. Nevertheless, production and excretion are again matched at a new steady-state Paco2. Therefore, the Paco2 is regulated primarily by neural respiratory factors and is not subject to regulation by the rate of CO2 production. Hypercapnia is usually the result of hypoventilation rather than of increased CO2 production. Increases or decreases in Paco2 represent derangements of neural respiratory control or are due to compensatory changes in response to a primary alterat Continue reading >>

    What a fantastic question!! Oh big pharma, here we go again. These pharm companies will work any sort of magic to keep their drugs branded (or extend their drug patent).
    Soo let's break it down..
    What we know (factoids):
    Basaglar has the same protein sequence and a similar glucose-lowering effect (compared to Lantus)
    Basaglar was released as a new source for patients looking for a lower cost alternative to Lantus.
    The FDA does not call it a “biosimilar” OR the generic drug for Lantus for regulatory reasons, BUT it can essentially be thought of as an alternative form of Lantus.
    Legally we CANT call it generic even though Basaglar has an amino acid sequence identical to Lantus AND in Europe it was approved by the EMA as the first insulin biosimilar under the brand name Abasria in 2014.
    In the US the product has been deemed a Lantus ‘follow-on,’ neither a biosimilar nor a generic but a branded biopharmaceutical in its own right.

    Basaglar can not be substituted for the generic of Lantus (in the US). Meaning if you have been getting Lantus you need a whole new script for Basaglar!
    In recent news the FDA passed a new law allowing more competitive into the market place.
    So how did this happen? In September 2015 the manufacture of Lantus (Sanofi) came to a settlement with Eli Lily (manufacturers of Basaglar).
    In this settlement Lilly agreed to pay royalties to Sanofi in exchange for a patent license. Lilly also pledged to wait to sell its pen-packaged biosimilar version of Lantus until December 15, 2016. (Wow! Way to help consumers, eye roll)
    Keep in mind, Lantus is Sanofi's best-selling product, with more than $7 billion dollars of sale in 2015.
    So what we really know: (???)
    None of this answers your question
    Big pharma will use any slew of wording to rebrand or in this case limit the competition (even at the cost of consumers)
    We don't know yet if in the US there will be great discounts for Basaglar products due to the greater cost to manufacture this drug (factor in now royalties!)

    Some retailers are fitting back against this nonsense. See what CVS is doing in response:
    Cvs is removing Lantus and Toujeo from its Caremark formularies and will start only covering Basaglar.
    Last note:
    So in a sense there is now a ‘generic’ alternative to Lantus on the market. The brands will always remain on the market so consumers can have more options for their care. And yes people come in all the time asking only for these uber expensive brands.

    Speak to your MD or awesome pharmacist to see if they can help you switch over!

    Insulin is an interesting thing. Blood sugar can vary from dangerously high to dangerously low in just an hour or two, and insulin’s job is to keep it level and in safe range.
    Keep in mind that if not diabetic, your blood sugar normally goes quite high (around 140) after a meal, and then is carefully brought back down to normal by small, carefully controlled doses of insulin made “on demand” by your pancreas’s beta cells. They need to sense your blood sugar level, your upcoming demands for energy, and to some extent, the amount of sugar you are digesting now that will soon reach your blood, so as to dose you correctly.
    The natural insulin that does all this has a very fast action, working within about 20 minutes and being totally used up in an hour or so. This type of insulin, known as Insulin R (Regular) went generic a long time ago. But for everyday diabetic use, it is usually very undesirable. Think about it. Do you wish to monitor your blood sugar every 15 minutes and then inject the exact appropriate amount of fast-acting insulin for the next hour? Including when you sleep? That is what your pancreas would do.
    You are relatively clumsy with insulin injections, and as a diabetic you generally do them less often. So you need a slow action insulin for the whole day, plus often another faster acting dose at mealtimes to handle the peak demand. Making the slow-acting dose have a very flat, consistent action over the entire day is a huge technical challenge and has only recently (2003 or so) become feasible. And the ones from 2003 (Lantus and later Levemir) are pretty good but not ideal. They have a definite peak time (which can be dangerous if mistimed) and a definite tailing off of action, meaning your blood sugar may be rising for some time before you can take more. They can also be inconsistent day to day, making that peak and tail-off time even more dangerous as they are unpredictable.
    So the race is on to make better, smoother, more consistent insulin action profiles for long-acting insulins. That takes research and lots of experiments and passing FDA tests, which is mucho expensive.

    Treating diabetics in hospital with ketoacidosis or pretty much any life-threatening condition may also require super-fast acting insulins, which also require research.

Severe Metabolic Acidosis In The Alcoholic: Differential Diagnosis And Management

1 A chronic alcoholic with severe metabolic acidosis presents a difficult diagnostic problem. The most common cause is alcoholic ketoacidosis, a syndrome with a typical history but often misleading laboratory findings. This paper will focus on this important and probably underdiagnosed syndrome. 2 The disorder occurs in alcoholics who have had a heavy drinking-bout culminating in severe vomiting, with resulting dehydration, starvation, and then a β- hydroxybutyrate dominated ketoacidosis. 3 Awareness of this syndrome, thorough history-taking, physical examination and routine laboratory analyses will usually lead to a correct diagnosis. 4 The treatment is simply replacement of fluid, glucose, electrolytes and thiamine. Insulin or alkali should be avoided. 5 The most important differential diagnoses are diabetic ketoacidosis, lactic acidosis and salicylate, methanol or ethylene glycol poisoning, conditions which require quite different treatment. 6 The diagnostic management of unclear cases should always include toxicological tests, urine microscopy for calcium oxalate crystals and calculation of the serum anion and osmolal gaps. 7 It is suggested here, however, that the value of th Continue reading >>

    Hello and Happy New Year! I've been on Keto since the start of December. I've had some bad moments (involuntary/voluntary cheats) at the very beginning and know that eating carbage isn't helping me and my health improvement goals and I have those desires absolutely under control. I'm not hungry so I don't eat which is something I've never experienced before! I love this WOE!!!
    Here's my current dilemma. I'm so stinking tired!!! All of the time! I can never get enough sleep! I read that if you're energy levels are low to eat fat. This morning I had some chicken bone broth with butter and coconut oil and took the kids to school. I felt so sleepy behind the wheel and I haven't felt like that in years. I came home and made myself some BPC, but I'm still sooooo tired. I added salt to both my broth and coffee. I feel nauseated and don't feel like eating especially since I'm not hungry and I always used to be hungry. It seems that I typically eat once a day and sometimes twice a day.

    What gives? What am I missing? I am taking daily vitamins, my high blood pressure and cholesterol meds. Do I need to also supplement with magnesium and potassium? I've been getting plenty of fluids. I don't feel like I caught some bug. Am I still converting to fat burning? Feeling confused but not giving up. Thank you in advance!

    If you started in December, and haven't been solidly practicing keto throughout that period, you are probably still experiencing keto flu.
    Yes, adding electrolytes can help with some symptoms of keto flu, so consider adding that (do a search for Ketoaid in the box at the top of the forums...that's one way to get them in). Some folks also take some bone broth, with a little added salt & fat, to help.
    Keep the carbs below 20g/day, sufficient protein, and fat to satiety. Keep doing that. If you go another month and still having issues, then you might look at what else to change.

    Fat adaptation isn't instant. And it takes longer for some folks than for others. You'll start to feel it once you're fully fat-adapted. Hang in there.
