We continue our throwback Thursday posts with a look at print ads from the archives containing 40 years’ worth of materials. This week, we dug up an old, very green, pulmonary catalog.

Much like the fields of spirometry and respiratory therapy, colors that might appeal to our customers have clearly changed over the past four decades. Our focus, however, on spirometry and other pulmonary products has remained unchanged.

The 1977 Pulmonary Function Catalog shows a cross section of a bronchiole surrounded by alveoli which are pasted into what appears to be a flow-volume loop. Perhaps for aesthetic reasons, the y-axis representing flow shows only positive values, or expiration, and negative values, or inspiration, are not represented in this rendering. As a result, the entire loop, while eye-catching, sits on top of the volume axis.

In contrast, our latest pulmonary and respiratory catalog features ViroMax, HydroMax and VBMax filters that are designed for use as bacterial viral filters, HME filters, and spirometry filters, respectively.

The evolution of our pulmonary catalog over the past four decades mirrors our growth as a company during that time. Our portfolio of products has expanded from simple supplies to highly efficient spirometry and anesthesia filters that are available around the world.

And we couldn’t have done it without the feedback from clinicians, patients, and our distributors. Thank you for supporting us!
