Arterial Blood Gas

Again, look at the chart. Alkalosis is present (increased pH) with the HCO3 increased, reflecting a primary metabolic problem. Treatment of this patient might include the administration of I. V. fluids and measures to reduce the excess base. ? Copyright 2004 Orlando Regional Healthcare, Education & Development Page 11 Arterial Blood Gas Interpretation Compensation Thus far we have looked at simple arterial blood gas values without any evidence of compensation occurring. Now see what happens when an acid-base imbalance exists over a period of time. When a patient develops an acid-base imbalance, the body attempts to compensate. Remember that the lungs and the kidneys are the primary buffer response systems in the body. The body tries to overcome either a…

Arterial Blood Gas

Understanding arterial blood gases can sometimes be confusing. A logical and systematic approach using these steps makes interpretation much easier. Applying the concepts of acidbase balance will help the healthcare provider follow the progress of a patient and evaluate the effectiveness of care being provided. Copyright 2004 Orlando Regional Healthcare, Education & Development Glossary ABG: arterial blood gas. A test that analyzes arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of ventilation. Acidosis: a pathologic state characterized by an increase in the concentration of hydrogen ions in the arterial blood above the normal level. May be caused by an accumulation of carbon dioxide or acidic products of metabolism or…

Homeostatic Mechanism

Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state, while the world around it is changing constantly. There are many steps in the process of homeostasis. First, there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center, which decides the response. The information entering into the control center is called the afferent pathway. During the efferent pathway, the information is sent out from the control center to the effector. The effector provides the means for the control center’s response, returning the body back to normal. An example of a…

Hardness of Water

The hardness of water was determined using the methods of titration, conductivity, and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present in water are Ca2+ and Mg2+ ions. Even though hard water does affect a person’s health, hard water can still have harmful effects in an industrial environment, appliances in a household setting, and certain cleaning task. 2For example, when hard water repeatedly goes through pipes, the water causes deposits that eventually build…

Case Vignettes in Acid-Base Balance

A 14-year-old girl with cystic fibrosis has complained of an increased cough productive of green sputum over the last week. She also complained of being increasingly short of breath, and she is noticeably wheezing on physical examination. Arterial blood was drawn and sampled, revealing the following values: Questions: 1. How would you classify this girl’s acid-base status? 2. How does cystic fibrosis cause this acid-base imbalance? 3. How would the kidneys try to compensate for the girl’s acid-base imbalance? 4. List some other causes of this type of acid-base disturbance. Vignette #2: A 76-year-old man complained to his wife of severe sub-sternal chest pains that radiated down the inside of his left arm. Shortly afterward, he collapsed on the living…

Case Vignettes in Acid-Base Balance

Choose three of the four vignettes and BRIEFLY answer the questions that follow. Normal Levels of Substances in the Arterial Blood: pH 7.40 + 0.05 pCO2 (partial pressure of carbon dioxide) 40 mm Hg pO2 (partial pressure of oxygen) 90 – 100 mm Hg Hemoglobin – O2 saturation 94 – 100 % [HCO3-] 24 meq / liter Vignette #1: A 14-year-old girl with cystic fibrosis has complained of an increased cough productive of green sputum over the last week. She also complained of being increasingly short of breath, and she is noticeably wheezing on physical examination. Arterial blood was drawn and sampled, revealing the following values: pH 7.30 pCO2 50 mm Hg pO2 55 mm Hg Hemoglobin – O2 saturation…

Fluid, Electrolyte, and Acid-Base Balance: Introduction to Body Fluids

  Fluid Compartments Water occupies two main fluid compartments Intracellular fluid (ICF) – about two thirds by volume, contained in cells Extracellular fluid (ECF) – consists of two major subdivisions Plasma – the fluid portion of the blood Interstitial fluid (IF) – fluid in spaces between cells Other ECF – lymph, cerebrospinal fluid, eye humors, synovial fluid, serous fluid, and gastrointestinal secretions Extracellular and Intracellular Fluids Water is the universal solvent Solutes are broadly classified into: Electrolytes – inorganic salts, all acids and bases, and some proteins Electrolytes determine the chemical and physical reactions of fluids Electrolytes have greater osmotic power than nonelectrolytes Water moves according to osmotic gradients Nonelectrolytes – examples include glucose, lipids, creatinine, and urea Each fluid…
