Objective 50: Demonstrate spirometer use and examine spirogram data

The very top video demonstrated nicely the use of the spirometer.  I am not an expert at spirometers but I am guessing the one they are using in the video is of a newer model because while I was researching, there was all kinds of spirometer models that was being used.  None of them being electronic.  The video taught me how to use a spirometer, that is all I can say.  The next video taught me about reading a spirogram data, all the intricacies of lung volume and capacity.
