Melissa,
My experience in the PNS is small so far, but I was told by someone with
technical knowledge that the PNS has a lower maximum suction than the
Lactina, 015 and N. III. I'm trying to remember--- does the Lactina max out
at 220-240mm/hg? (I may have all the numbers wrong; someone please fill them
in!)
