Topic: The current state of liquid oxygen: It\'s growing and still \"the choice\" for certain patient groups.
Open Standard Media Player version 1.3
from my patient perspective: Liquid oxygen is the BEST, superior system, lighter weight, compact, lasts longer than heavier compressed gas O2, or concentrators. Portable concentrators rely on batteries, purity is 7 to 10% lower than liquid. I use the Caire high flow liquid oxygen portable tanks to keep active, they maintain my oxygen saturation the best.
