You can get an eBook version here or a physical copy of the book here. Many new nurses feel they are not comfortable with interpreting ABGs after they graduate.

Interpretation of arterial blood gases ABGs is a crucial skill that a lot of student nurses and medical practitioners need to learn. It is used to determine the extent of the compensation by the buffer system and includes the measurements of the acidity pH , levels of oxygen, and carbon dioxide in arterial blood. Unlike other blood samples obtained through a vein, a blood sample from an arterial blood gas ABG is taken from an artery commonly on radial or brachial artery. The pH is the concentration of hydrogen ions and determines the acidity or alkalinity of body fluids. The normal ABG level for pH is 7. PaCO 2 or partial pressure of carbon dioxide shows the adequacy of the gas exchange between the alveoli and the external environment alveolar ventilation.

You begin to interpret the results to determine his acid base status. ABGs can also measure glucose, lactate, electrolytes, hemoglobin, and various toxicology levels to name a few. Unfortunately, analyzing blood gases can be confusing to learn at first. Medical topics are made easy with every EZmed blog post, and today you will learn a simple trick to interpret blood gases using the tic-tac-toe method! First, we need to know the normal values of a blood gas before we can start to interpret it. A normal PaCO2 range is This is easy to remember - simply take the decimal numbers from the pH 0.

It has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. The acid base status of this example is tic tac toe blood gases acidosis with metabolic compensation. Since CO2 represent respiratory and it is under the acid column with your pH you have respiratory acidosis going on.

This laboratory test is also used to determine the extent of the buffer system in compensating, and includes the measurements of the following:. Interpreting ABG will also allow us to differentiate these acid-base conditions, and if the body is compensating or not. Keep in mind the normal values, acidic value, and alkalotic value. Check if the values are under normal, acidosis, or alkalosis. If the pH is less than 7. If the PCO2 is over 45, it should be placed under Acid and if less than 35, then it should be under Base.

Loved the explanation Reply. Remember that bicarb is a base. This happens in diarrhea , ketosis, and kidney disorders. Therefore, it is not doing anything to compensate for the metabolic disorder otherwise CO2 would have been under the acid column. You need to figured out what you have. The kidneys activate its compensatory process albeit slow, often 24 hours or more by increasing the excretion of metabolic acids through urination, which increases blood bicarbonate. Is it metabolic or respiratory? Here is a guide to help you understand it:. On the contrary, alkalosis is a condition wherein the blood is relatively too basic high pH , there are also two types of alkalosis: respiratory alkalosis and metabolic alkalosis. To simplify this technique even further, keep these goals in mind. Tic-Tac-Toe Method So what is the tic-tac-toe method?

This question provides a scenario about arterial blood gas results. As the nurse, you must determine if this is a respiratory or metabolic problem, alkalosis or acidosis along with if it is uncompensated, partially or fully compensated based on the results.

On the contrary, alkalosis is a condition wherein the blood is relatively too basic high pH , there are also two types of alkalosis: respiratory alkalosis and metabolic alkalosis. These can include:. Eliminate any stress or confusion, and walk away fully understanding! The first step is you need to familiarize yourself with the normal and abnormal ABG values when you review the lab results. Thanks,this material is helpful. The following sources are used as references for this guide. The best and fun way of interpreting arterial blood gas is by using the tic-tac-toe method below:. One type of acid-base imbalance is acidosis wherein the blood is relatively too acidic low pH. Alternatively, when there is an increase in bicarbonates present, then metabolic alkalosis results. A pH greater than 7. The normal values for HCO3 is You will receive high-yield information, visuals, study guides, and tricks to remember it all! This means a lot for me Reply.
