@macinfo2020 @windwalker Hi! I think Terri put the wrong article up just now for the saline. (The article she posted was meant for a different discussion.) Here are two articles that Terri has posted here about 7 % saline: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4850692/pdf/13104_2016_Article_2054.pdf and https://www.resmedjournal.com/action/showPdf?pii=S0954-6111%2811%2900254-X . I think the charts she was refering to are Tables 2 and 3 in the first (ncbi) article.
