What is BASAL METABOLIC RATE? What does BASAL METABOLIC RATE mean? BASAL METABOLIC RATE meaning - BASAL METABOLIC RATE definition - BASAL METABOLIC RATE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(hkg)). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food). In bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) is used. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mammals. Metabolism comprises the processes that the body needs to function. Basal metabolic rate is the amount of energy expressed in calories that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. Basal metabolic rate (BMR) affects the rate that a person burns calories and ultimately whether that individual maintains, gains, or loses weight. The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals. It is influenced by several factors. BMR typically declines by 12% per decade after age 20, mostly due to loss of fat-free mass, although the variability between individuals is high. The body's generation of heat is known as thermogenesis and it can be measured to determine the amount of energy expended. BMR generally decreases with age and with the decrease in lean body mass (as may happen with aging). Increasing muscle mass has the effect of increasing BMR. Aerobic (resistance) fitness level, a product of cardiovascular exercise, while previously thought to have effect on BMR, has been shown in the 1990s not to correlate with BMR when adjusted for fat-free body mass. But anaerobic exercise does increase resting energy consumption (see "aerobic vs. anaerobic exercise"). Illness, previously consumed food and beverages, environmental temperature, and stress levels can affect one's overall energy expenditure as well as one's BMR. BMR is measured under very restrictive circumstances when a person is awake. An accurate BMR measurement requires that the person's sympathetic nervous system not be stimulated, a condition which requires complete rest. A more common measurement, which uses less strict criteria, is resting metabolic rate (RMR).

Metabolic Acidosis

Patient professional reference Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find one of our health articles more useful. See also separate Lactic Acidosis and Arterial Blood Gases - Indications and Interpretations articles. Description Metabolic acidosis is defined as an arterial blood pH <7.35 with plasma bicarbonate <22 mmol/L. Respiratory compensation occurs normally immediately, unless there is respiratory pathology. Pure metabolic acidosis is a term used to describe when there is not another primary acid-base derangement - ie there is not a mixed acid-base disorder. Compensation may be partial (very early in time course, limited by other acid-base derangements, or the acidosis exceeds the maximum compensation possible) or full. The Winter formula can be helpful here - the formula allows calculation of the expected compensating pCO2: If the measured pCO2 is >expected pCO2 then additional respiratory acidosis may also be present. It is important to remember that metabolic acidosis is not a diagnosis; rather, it is a metabolic derangement that in Continue reading >>

    I purchased both a CVS branded glucose monitor and an Precision xtra glucose monitor.
    While waiting for amazon to deliver the Precision extra I started testing with the one from CVS.
    The tests from the CVS brand had my glucose ranging from the low 70's to the mid 80's. That's great right?
    However, when I started testing with the Precision extra my numbers were 30 points higher! After using a third monitor I borrowed from a friend I decided that the CVS branded monitor is wrong. It was giving glucose readings that were too low.

    I thought I was in ketosis since I tested my ketone levels at 1.9 last week before I received glucose strips for the Precision xtra. So I have high fasting blood sugar of 120 and ketones of 1.9. Can someone help me interpret my numbers?

  2. Psc15771

    I'm relatively new to the forum but I've been reading and doing my own n=1 off and on. I believe that ketone levels greater than .5 indicate your body is in ketosis. Fasting blood sugar of 120 would be in the pre-diabetes T2 range. What I've been shooting for and over the last month have been able to achieve with the keto diet is fasting blood sugar less than 100. My ketones have been between 1.4 and 3.5, so I'm in ketosis but I don't believe my body has fully keto adapted yet.

  3. Psc15771

    I've also noticed that the "dawn" phenomenon of my fasting blood sugar being quite a bit more than my bedtime blood sugar is gone. I used to consistently see a 20 - 30 point rise between my bedtime blood sugar and my morning blood sugar.

Intro To Arterial Blood Gases, Part 2

Arterial Blood Gas Analysis, Part 2 Introduction Acute vs. Chronic Respiratory Disturbances Primary Metabolic Disturbances Anion Gap Mixed Disorders Compensatory Mechanisms Steps in ABG Analysis, Part II Summary Compensatory Mechanisms Compensation refers to the body's natural mechanisms of counteracting a primary acid-base disorder in an attempt to maintain homeostasis. As you learned in Acute vs. Chronic Respiratory Disturbances, the kidneys can compensate for chronic respiratory disorders by either holding on to or dumping bicarbonate. With Chronic respiratory acidosis: Chronic respiratory alkalosis: the kidneys hold on to bicarbonate the kidneys dump bicarbonate With primary metabolic disturbances, the respiratory system compensates for the acid-base disorder. The lungs can either blow off excess acid (via CO2) to compensate for metabolic acidosis, or to a lesser extent, hold on to acid (via CO2) to compensate for metabolic alkalosis. With Metabolic acidosis: Metabolic alkalosis: ventilation increases to blow off CO2 ventilation decreases to hold on to CO2 The body's response to metabolic acidosis is predictable. With metabolic acidosis, respiration will increase to blow off CO Continue reading >>

    carb depletion ?

    carb depletion ? did 50mins moderate cardio last night, by the end starting to get hungary, so necked a whey shake and went home for a meal. Afterwards felt kinda weak and odd, so was thinking that maybe I had become abit depleted so ate a banana and within about 30mins felt OK again.

  2. Malika

    RE: carb depletion ?

    Yes, You probably deplated your muscles of carb(glycogen) after this amount of cardio... Maybe you should have taken some whey+maltodextrose just after it to replenish your glycogen level.

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.

4.5 Respiratory Acidosis - Compensation

Acid-Base Physiology 4.5.1 The compensatory response is a rise in the bicarbonate level This rise has an immediate component (due to a resetting of the physicochemical equilibrium point) which raises the bicarbonate slightly. Next is a slower component where a further rise in plasma bicarbonate due to enhanced renal retention of bicarbonate. The additional effect on plasma bicarbonate of the renal retention is what converts an "acute" respiratory acidsosis into a "chronic" respiratory acidosis. As can be seen by inspection of the Henderson-Hasselbalch equation (below), an increased [HCO3-] will counteract the effect (on the pH) of an increased pCO2 because it returns the value of the [HCO3]/0.03 pCO2 ratio towards normal. pH = pKa + log([HCO3]/0.03 pCO2) 4.5.2 Buffering in Acute Respiratory Acidosis The compensatory response to an acute respiratory acidosis is limited to buffering. By the law of mass action, the increased arterial pCO2 causes a shift to the right in the following reaction: CO2 + H2O <-> H2CO3 <-> H+ + HCO3- In the blood, this reaction occurs rapidly inside red blood cells because of the presence of carbonic anhydrase. The hydrogen ion produced is buffered by intrac Continue reading >>
