I spent about 1 hour completing this tutorial. I found it to be extremely helpful. Arterial blood gas interpretation can be a little tricky and I have always had to think about these situations for a while to understand them. This tutorial provided a step by step guide to interpreting arterial blood gases. I am really impressed. I feel much more proficient after doing all of the case studies. The content is of very high quality. The concepts are represented accurately and completely. This is an excellent guide for a nursing student trying to understand and apply these concepts. This tutorial is an effective, interactive and fun learning tool.
