Oh my, dear Professor. I have been your fan since I was in medical school. Your book is absolutely amazing! It is suprising that you have this youtube channel. Hope to learn more from you and your book.

Dear Dr.Hanna, I wonder if we can curb the inaccuracies of pull back method by using end expiratory hold maneuver to eliminate the resp variation during pull back?

[@eliashanna8248]

In general, in all hemodynamic studies, I suggest against end-expiratory hold. The patient strains during this hold, which: (1) reduces venous return, (2) causes a direct positive pressure effect on the measured pressures. Also, it is not consistent as the patient may inadvertently inspire during the hold.
