Dec 6, 2015 · The Jones Pulmonor was a bellow spirometer, and most of the inside was empty space. This photo is of the back side of the spirometer. If the front could be seen the box on the side was where a piece of pressure-sensitive graph paper was placed. A pressure stylus would inscribe the volume-time curve from a spirometry maneuver.

May 12, 2014 · Late in 2012 the Global Lung Function Initiative (GLFI) released their reference equations for spirometry. Although not without some criticism this was an important step towards the development of a single spirometry reference equation that can be …

May 26, 2014 · Lately I’ve been looking at videos about lung volumes and have seen a half dozen presenters describe lung volume subdivisions using the same graph we’ve come to know and love with varying degrees of effectiveness and obfuscation.
