first of all, your part 1 and part 2 of hemodynamic monitoring is incredibly descriptive and helpful to me. I had a really hard time understanding physiology and I truly feel like I got a decent hand on things after this. I'll be coming back to the videos as needed. I do have some difficulty with the stammering speech, though. I had to go back and listen to each 15-20 seconds to figure out the full sentence of what you were saying. Clearly, the narrator is intelligent and helpful. Thank you for these!
