Vital Reaction vs Professional Hydrogen Inhalation Machines

Output is the rated volume of hydrogen gas produced per minute, expressed in millilitres per minute (ml/min). It is the most direct measure of how much hydrogen a machine delivers and is the primary input into how long a session needs to be to deliver a given volume.

Typical residential machines may produce in the low hundreds of ml/min, while professional-grade systems are engineered to produce several thousand ml/min for shared and multi-user environments. Always check whether the figure quoted is total flow or per-nasal-cannula flow.

Output should be considered alongside duty cycle (continuous vs intermittent) and purity. A higher number on its own is not necessarily better if the machine is not rated for continuous use.
