5. PRINCIPLE OF OPERATION
Gas supply: 3.9 bar to 6.0 bar
Therapy outlet: Universal ‘fir-tree’ type
Therapy flow accuracy: +/- 10%
Outlet pressure: 4.2 bar (61 PSI) nominal
Oxygen from the cylinder is reduced to a constant pressure and used to fill
a reservoir at a rate set by the flow setting knob.
During exhalation, there is no oxygen flow out of the unit, so the reservoir
fills up to a level determined by the flow setting.
As an inhalation begins, the small suction at the nose makes a valve open.
A timed pulse of oxygen is delivered from the reservoir to the patient. The
timing is designed so that inhaled gas flows deep into the lungs.
Flows are set so that the oxygen delivered into the lung will be approximately
equivalent to the same constant flow. Flows into the reservoir are about a
third of the flow setting. This, combined with the number of settings will
normally give increases in duration of 3 to 5.
