PFT5 Nitrogen Washout

This is a brief introduction on how to conduct a nitrogen washout pulmonary function test on a patient. The purpose of this test is to measure total lung capacity.

Informative. Instructive good technique. Looks like Medgraphics equipment. Body Plethysmography has many advantages as well. Some patients potentially will "never" washout.

Hi, thanks for the video! Great explanation, and I loved seeing the test being explained in real time. I was wondering if you could explain the difference between minimum air volume (MAV) and functional residual capacity (FRC)? Are these two essentially the same thing, and if so, which is a more appropriate term to use?

Hi. Im interested in using the Optiflow device to prevent desaturation during rapid sequence induction of anesthesia. I wonder if it could achieve N2 washout even if someone is able to inspire room air orally.....? Could I use the optiflow device in conjunction with this test but have the patient inspiring normal air orally......?

Are you speaking about Second Gas effect?
