Arterial Blood Gas Intrepretation


The objectives for my module are:


Audience: Registered Nurses in Hospitals throughout Northern Colorado.

Behavior: Differentiate between or classify pH values according to three basic categories, Normal, Alkalosis, or Acidosis.

Condition: Given the attached informational slide.

Degree: Without error.

    I like the way you create your information. It is look simple and clear. My suggestion if you just do space between the title and the following information. Also, I think if you add a little shadow box as background for the first cable sentences may be that would be better.

  2. HI Ann,

    This is good engaging even for a non-science person like me. Here's where I got a bit confused.

    On the left, are the numbers for the hydrogen values? If not, what do those numbers represent? Perhaps they could be labeled.

    The polygon (octagon) for the hydrogen ion, is that shape used to represent positive hydrogen ions in general? (yes my science is rusty :>)

    If I read each row across, then the < 7.35 acidosis and the hydrogen graphic doesn't send me a clear message. Reading across how should I be interpreting this?

    I really like how the number of hydrogen ions increase based on the number to the left, but again I am not sure what that number represents... Are they PH Levels?

    Perhaps a little more text (labels) would better support the learner or enable the learner to more quickly recognize what the graphic is saying? Thanks - Kim

  3. Ann: I found your image to be well presented. It is easy to undersatnd. On top of the verbal explanation, the hydrogen ion boxes show to anyone that as they decrease alklosis increases and as they increase acidosis increases which is the main idea in the image. In other words the increasing or decreasing of hydrogen ions affects the PH level.
    I say it is well done.
