You must always interpret them in light of the patient’s history and clinical presentation. An arterial blood gas (ABG) specifically tests blood taken from an artery. Normal. Many studies have reported normal ranges of umbilical cord blood gases, which vary greatly due to many factors. These ranges vary from lab to lab and depend upon the elevation above sea level. The normal values listed here—called a reference range—are just a guide. The normal range for ABGs is used as a guide, and the determination of disorders is often based on blood pH. It also measures your body’s acid-base (pH) level, which is usually in balance when you’re healthy. The PaCO2 is directly measured and is used to estimate CO2 exchange. Understanding the print outs 4. PaO2. Arterial blood pH: 7.38 to 7.42; Oxygen saturation (SaO2): 94% to 100%; Bicarbonate (HCO3): 22 to 28 milliequivalents per liter (mEq/L) At altitudes of 3,000 feet (900 meters) and higher, the oxygen value is lower. The measurement of arterial blood gas tensions and oxygen saturation (So 2) is a cornerstone in the evaluation of pulmonary disease severity. As we start our Arterial Blood Gas course, I want to start by helping you understand what is included in an ABG and why we use ABGs in our patients.Sometimes ABGs can be very intimidating because there are a lot of values to look at, but hopefully this will help to … Blood oxygen saturation (SaO2): The amount of oxygen carried by the hemoglobin in the red blood cells. At altitudes of 3,000 feet and above, the oxygen values are lower. ABG Predicted Normal Values Arterial blood gas analysis is important in managing patients with cardiopulmonary diseases. PaCO2. An Arterial Blood Gas, or ABG for short, is a test that measures the blood levels of oxygen (PaO2), carbon dioxide (PaCO2), and acid-base balance (pH) in the body.It’s a test that is used to assess how well oxygen is being distributed throughout the body and how well carbon dioxide is being removed. Normal. The normal range of PaO 2 is 80 to 100 mm Hg. Normal value ranges may vary slightly among different laboratories. Simple and mixed disorders 6. Interpreting an arterial blood gas (ABG) is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel. Acidity or alkalinity of the blood can be measured with pH values. Blood oxygen levels (PO 2 level; normal range 10.5 to 13.5 KPa) - if the PO 2 level is low, it indicates an abnormally low concentration of blood oxygen (hypoxaemia). 2. The following six-step process helps ensure a complete interpretation of every ABG. Arterial blood gas (ABG) analysis is an important laboratory method that provides reliable information about the patient’s metabolic status and respiratory physiology. Before actually starting to interpret the ABG reports, one needs to remember the following normal values, without which, it is impossible to analyze anything. When arterial blood is analyzed, the main variables are: pH - a measure of how acidic or alkaline the blood is. This results in a slightly more acidic “normal” pH range. 229 arterial blood gases Proceedings of Singapore Healthcare Volume 20 Number 3 2011 Table 1. VD/VT = PaCO2 – PECO2/PaCO2: Normal values for the dead space to tidal volume ratio are 20-40%. Print primer [237k PDF*] Introduction; Acid-Base Status . Cathy Parkes RN, covers Arterial Blood Gas (ABG) Interpretation - Introduction: Normal Ranges & Steps in Interpretation. Terms and Normal Values; How the Data Are Presented; Before you get started; A Step-wise Approach to Interpretation. Arterial blood gases should never be interpreted by themselves. The pH of a solution is equal to the negative log of the hydrogen ion concentration in that solution: pH = – log [H+]. As dead space increases, there is less equilibration between arterial and alveolar CO2 tensions and this ratio increases. A Primer on Arterial Blood Gas Analysis by Andrew M. Luks, MD. Arterial blood pH, the amount of hydrogen ions in the blood: A pH of 7.35-7.45 is considered normal. robyn811. Arterial blood pH of 7.38 - 7.42; Oxygen saturation (SaO2) - 94 - 100%; Bicarbonate - (HCO3) - 22 - 28 mEq/L; Note: mEq/L = milliequivalents per liter; mmHg = millimeters of mercury. An arterial blood gas (ABG) test measures the acidity (pH) and levels of oxygen and carbon dioxide in the blood. Normal values for PaCO2 are usually 35-45 mmHg. Gravity. The normal values listed here—called a reference range—are just a guide. Learn normal values arterial blood gas with free interactive flashcards. Normal Values. by Kemal Gunaydin Introduction Measurements of PaO2, PaCO2, SaO2, pH, and bicarbonate values are made with arterial blood gas (ABG) analysis in order to determine the acid-base balance and respiratory regulation. The normal range is 7.35 - … The test is commonly known as a blood gas analysis or arterial blood gas (ABG) test. The normal range is 7.35 to 7.45 Remember: pH > 7.45 = alkalosis pH< 7.35 = acidosis PO2 The partial pressure of oxygen that is dissolved in arterial blood. These ranges vary from lab to lab and depend upon the elevation above sea level. Instead, it provides the values of the following FIVE parameters. The normal range of SaO 2 is 95% to 100%. adult hemoglobin at normal temperature and blood pH. Your lab may have a different range for what's normal. The most common ABG abnormalities detected relate to an excess of acid. PaO 2 tells us about the partial pressure of oxygen dissolved in arterial blood. Values that fall outside of the normal range, as well as shifts in blood pH that occur as a result are referred to as abnormal blood gases. Most neonatologists use venous blood gas in neonates for metabolic evaluation and monitoring gas exchange, but not for monitoring oxygenation 1) . The first step in evaluating a blood gas report is to look at pH. What are the most common arterial blood gas abnormalities? Normal Blood Gases: Arterial: Venous: pH: 7.35 – 7.45: 7.32 – 7.42: Not a gas, but a measurement of acidity or alkalinity, based on the hydrogen (H+) ions present. Learn vocabulary, terms, and more with flashcards, games, and other study tools. You can check all the values seen in ABG on wikipedia. The normal values listed here—called a reference range—are just a guide. Normal Range: 80-100 mmHg Represents the gas & dissolved oxygen in the blood. ABG interpretation is especially important in critically ill patients. 3 At the low PaO2 values seen on the steep slope of the curve in Figure 4-10, a small increase in PaO2 results Background: Umbilical cord blood gas values are better indicators of perinatal asphyxia than Apgar scores. What does the Arterial Blood Gas Analysis measure? PaO2: 80 to 100 mm Hg. Video Transcript . An arterial blood gas (ABG) test measures the acidity (pH) and levels of oxygen and carbon dioxide in the blood. A venous blood gas test is identical to an arterial blood gas measurement, except the blood is drawn from a venous site. Terminology and normal arterial blood gases 3. Normal Values in Arterial Blood Gas . Arterial blood gas analysis is used to measure the pH and the partial pressures of oxygen and carbon dioxide in arterial blood. Your lab may have a different range for what's normal. Choose from 500 different sets of normal values arterial blood gas flashcards on Quizlet. 7.35-7.45. From this baseline, you can then begin to recognise significant variations in a patient’s results, which could indicate clinical deterioration. ABG parameters, reference range and alert values (reported by the authors’ lab). Reference values for arterial blood gases should be based on subjects representative of the general healthy population. – The partial pressure of oxygen– It is the pressure of oxygen in the arterial blood (dissolved in plasma) and is denoted by P02.
