SECTION 2
METHOD OF OPERATION
Oxygen automatically and continuously flows from the cylinder to the breathing bag when the unit is pulled
from the base.
During inhalation, and whenever the bag flattens, the oxygen regulator increases the oxygen flow into the
breathing bag.
During inhalation, oxygen passes from the breathing bag through the scrubber and into the mouthpiece.
During exhalation, carbon dioxide laden air is exhaled through the scrubber and then into the breathing
bag.
During inhalation and exhalation, carbon dioxide is absorbed by the lithium hydroxide scrubber.
Occasionally, during low work rates, the oxygen regulator supplies more oxygen than the user can
consume. When this occurs, the excess gas automatically vents through the relief valve.
The starting of the oxygen flow, the increased flow rate during high work rates, and the occasional venting
of gas through the relief valve, all occur automatically: the user needs only to breathe.
