The image shows a man standing in front of a projector screen in a lecture hall, giving a presentation. He is wearing a blue shirt and glasses and appears to be giving a lecture to a group of people sitting in chairs. The presentation is titled "39 y/o with Myasthenia Gravis exacercation, Hn, DM, S/F Plasmapheresis". 

On the screen, there is a slide with text and images related to the presentation. The slide has a title that reads "Plan: RJ Dialysis catheter". Below the title, there are three images of the catheter, each with a different color and label. The first image is of a catheter with a label that says "Does the guidewire enter into the intended vessel? Did the guideway remain in the intended vessels? Identify the guideways from entry point still in vessel." The second image is a diagram of the diaphragm, which is a type of catheter that is used to identify the internal structure of a vessel. The third image is an illustration of a fish, which appears to have a label on it.

The audience is attentively listening to the man's presentation.
