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 >>

    Ketosis is a normal metabolic process in your body. If you don't have sufficient glucose in your body, it will turn to burning fat. A process we call ketosis.
    It does not cause kidney damage in healthy people with normal balanced food intake.

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.

Respiratory Acidosis

DEFINITION Respiratory acidosis = a primary acid-base disorder in which arterial pCO2 rises to an abnormally high level. PATHOPHYSIOLOGY arterial pCO2 is normally maintained at a level of about 40 mmHg by a balance between production of CO2 by the body and its removal by alveolar ventilation. PaCO2 is proportional to VCO2/VA VCO2 = CO2 production by the body VA = alveolar ventilation an increase in arterial pCO2 can occur by one of three possible mechanisms: presence of excess CO2 in the inspired gas decreased alveolar ventilation increased production of CO2 by the body CAUSES Inadequate Alveolar Ventilation central respiratory depression drug depression of respiratory centre (eg by opiates, sedatives, anaesthetics) neuromuscular disorders lung or chest wall defects airway obstruction inadequate mechanical ventilation Over-production of CO2 -> hypercatabolic disorders Malignant hyperthermia Thyroid storm Phaeochromocytoma Early sepsis Liver failure Increased Intake of Carbon Dioxide Rebreathing of CO2-containing expired gas Addition of CO2 to inspired gas Insufflation of CO2 into body cavity (eg for laparoscopic surgery) EFFECTS CO2 is lipid soluble -> depressing effects on intrace Continue reading >>

Disorders Of Acid-base Balance

Module 10: Fluid, Electrolyte, and Acid-Base Balance By the end of this section, you will be able to: Identify the three blood variables considered when making a diagnosis of acidosis or alkalosis Identify the source of compensation for blood pH problems of a respiratory origin Identify the source of compensation for blood pH problems of a metabolic/renal origin Normal arterial blood pH is restricted to a very narrow range of 7.35 to 7.45. A person who has a blood pH below 7.35 is considered to be in acidosis (actually, physiological acidosis, because blood is not truly acidic until its pH drops below 7), and a continuous blood pH below 7.0 can be fatal. Acidosis has several symptoms, including headache and confusion, and the individual can become lethargic and easily fatigued. A person who has a blood pH above 7.45 is considered to be in alkalosis, and a pH above 7.8 is fatal. Some symptoms of alkalosis include cognitive impairment (which can progress to unconsciousness), tingling or numbness in the extremities, muscle twitching and spasm, and nausea and vomiting. Both acidosis and alkalosis can be caused by either metabolic or respiratory disorders. As discussed earlier in this Continue reading >>

    As always a history is taken. Laboratory evaluation includes serum glucose, serum electrolytes (with calculation of the anion gap), blood urea nitrogen (BUN), and plasma creatinine, urinalysis and urine ketones by dipstick, plasma osmolality, serum ketones (if urine ketones are present). That gives the needed information: diabetes with hyperosmolality and ketosis.

    Respiratory acidosis develops when air exhaled out of the lungs does not adequately exchange the carbon dioxide formed in the body for the inhaled oxygen in air. There are many conditions or situations that may lead to this. One of the conditions that can reduce the ability to adequately exhale carbon dioxide (CO2) is chronic obstructive pulmonary disease or COPD. CO2 that is not exhaled can shift the normal balance of acids and bases in the body ...
