In this lesson you will learn the WHY behind arterial blood gas which includes acid-base balance, oxygenation status, and other issues with results and exactly how to interpret them.
There are 3 basic steps to interpret an arterial blood gas. The first step is to look at the 3 main values, pH, PaCO2, and bicarb and determine if they are acidotic, alkalotic, or normal.
The second step is to determine if the source is metabolic or respiratory, and finally the third step is to determine if there is any compensation or fixing of the problem by the body.
This lesson teaches how to use the first trick method to interpreting arterial blood gases, the ROME method.
ROME stands for respiratory opposite, metabolic equal which helps you to interpret blood gases based on the direction of respiratory or metabolic status compared to the pH. This lesson walks you through the steps to understand each section of the ROME method.
In this lesson you will gain an understanding of the defining lab values associated with respiratory acidosis, low pH and high PaCO2.
You will also understand the causes, symptoms, and therapeutic management of respiratory acidosis.
