Most of those were regulated at the first stage to 20 or so. Delivery to the lungs would have been 1 psi or less. That 40 probably refers to cm or water column. Possibly mm Hg, but I doubt it. Amazingly, I lived thru and used a lot of the stuff pictured too! -SC- Great article, BUT, there is no way the old E+Js pumped 40 POUNDS of pressure into lungs.

I hope we see more posts and articles about old EMS. It's frightening that I LIVED through some of this progress. One clarification I'd like to make is that the E and J Lifeport III was actually a Lytport III. I've even found a Fire Engineering magazine with the device advertised. How many firemen were grateful for its development I cannot imagine. E and J also made the humongously heavy resuscitators preceding the Lytport. E and J became Ohio Chemical. If I remember well Life Support Products took their emergency respirator product line over. From there.... Emerson also manufactured iron lungs and was taken over by Respironics. Respironics stopped supporting the few iron lung devices that were sustaining polio victims a few years ago. They were in turn bought out by Philips. Another thing I noted is that the prone-pressure manual method of artificial respiration was used with many resuscitators/inhalators in the Fifties and earlier. But weren't resuscitators used on non-breathing patients even before the demand valve? I've also read about ambulance attendants, when riding in the back of old ambulances with the manifold-powered suction units, requesting the driver to modify his acceleration based on when suction was applied. I found out why when injecting Seafoam into the loosened brake vacuum hose of my old Honda! Take care KT Mr. Farah:
