Tube is too big for ring post pump. Can I apply ring before pumping?

So even at full 17.5 Mbar I'd be between 3 and 6 Hg Right? 1 mbar to in Hg = 0.02953 in Hg 10 mbar to in Hg = 0.2953 in Hg 20 mbar to in Hg = 0.5906 in Hg 30 mbar to in Hg = 0.8859 in Hg 40 mbar to in Hg = 1.1812 in Hg 50 mbar to in Hg = 1.4765 in Hg 100 mbar to in Hg = 2.953 in Hg 200 mbar to in Hg...

Thanks for the info. Using pump on lowest setting that goes to -17.5, doubt I'm anywhere near that. I stop pumping when I feel a little discomfort.

5 minutes twice a day at -75Mlbs. Should I go longer and/or more often or am I just doomed?
