    Hello,

    There is an excellent contemporary paper we published in DHM (2019) written by Peter Wilmshurst (who first reported immersion pulmonary oedema) available on pubmed central:

    In September I had major abdominal surgery, which required intubation for several hours. At extubation I suffered of the problem: I could not inhale more than 0.6 liters due to oedema.
    The therapy was a pulmonary exercise employing a 1/2" silicon hose inserted in a plastic bottle with 15 cm of physiological solution. I had to inhale freely and slowly, and exhale through the pipe, making the air to bubble inside the liquid. This creates a respiratory cycle with a significant average positive pressure, which helped to "push away" blood from my lungs. Repeating this exercise a number of times, in less than 24h the oedema was eliminated. After each exercise session (6 to 10 exhalation) I perceived the immediate increase of the volume of air which I was able to inhale.
    After this first-hand experience, I now think that our regulators should be tuned for minimal inhalation effort, and some larger exhalation effort, so the average pressure during the respiratory cycle remains significantly positive.
    I do not think it is a good idea to employ regulators with minimal exhale effort, as keeping a positive pressure in your lungs is healthy.

    Another paper is Scuba divers' pulmonary oedema: recurrences and fatalities by Dr Carl Edmonds, John Lippmann, Dr Sarah Lockley and Dr Darren Wolfers in Diving and Hyperbaric Medicine Volume 42 No 1 March 2012. Copy available at my web site via this page, see towards the bottom: Michael McFadyen's Scuba Diving Web Site.

    Also on that page is a detailed description of a dive (that I was also on) that led to the death of a close friend from IPE. I think this is also worth reading. I am now certain that some other people who died in diving accidents in Sydney in 1990s and 2000s were probably IPE, not drowning as reported.
