OXYGEN CYLINDER DURATION
Because the total delivery of oxygen via the BONSAI
to breathing rates, it is user adaptive in that the total oxygen delivered per minute will
automatically adjust with user need, as expressed by increased or decreased breathing rates�
For example, at all settings, twice as much oxygen per minute will be delivered if one breathes
twenty (20) times per minute as compared with ten (10) times per minute� Please refer to the
table below as a guide�
