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.
Causes of respiratory acidosis include: Diseases of the lung tissue (such as pulmonary fibrosis, which causes scarring and thickening of the lungs) Diseases of the chest (such as scoliosis) Diseases affecting the nerves and muscles that signal the lungs to inflate or deflate Drugs that suppress breathing (including powerful pain medicines, such as narcotics, and "downers," such as benzodiazepines), often when combined with alcohol Severe obesity, which restricts how much the lungs can expand Obstructive sleep apnea Chronic respiratory acidosis occurs over a long time. This leads to a stable situation, because the kidneys increase body chemicals, such as bicarbonate, that help restore the body's acid-base balance. Acute respiratory acidosis is a condition in which carbon dioxide builds up very quickly, before the kidneys can return the body to a state of balance. Some people with chronic respiratory acidosis get acute respiratory acidosis because an illness makes their condition worse.
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).

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

Approach To The Adult With Metabolic Acidosis
INTRODUCTION On a typical Western diet, approximately 15,000 mmol of carbon dioxide (which can generate carbonic acid as it combines with water) and 50 to 100 mEq of nonvolatile acid (mostly sulfuric acid derived from the metabolism of sulfur-containing amino acids) are produced each day. Acid-base balance is maintained by pulmonary and renal excretion of carbon dioxide and nonvolatile acid, respectively. Renal excretion of acid involves the combination of hydrogen ions with urinary titratable acids, particularly phosphate (HPO42- + H+ —> H2PO4-), and ammonia to form ammonium (NH3 + H+ —> NH4+) . The latter is the primary adaptive response since ammonia production from the metabolism of glutamine can be appropriately increased in response to an acid load . Acid-base balance is usually assessed in terms of the bicarbonate-carbon dioxide buffer system: Dissolved CO2 + H2O <—> H2CO3 <—> HCO3- + H+ The ratio between these reactants can be expressed by the Henderson-Hasselbalch equation. By convention, the pKa of 6.10 is used when the dominator is the concentration of dissolved CO2, and this is proportional to the pCO2 (the actual concentration of the acid H2CO3 is very lo
