Oxygen supply occurs at the beginning of inhalation when the gas is
mixed with ambient air directed to the lungs where it is absorbed. During
a later inhalation phase (when otherwise oxygen is to be directed to "dead
spaces") and during exhalation, the gas is economized by means of its
collecting in the reservoir.
Efficiency of this device is about 90% - 70%; it is calculated based on final
oxygen quantity supplied to the lungs in comparison with constant flow
where efficiency is only 20% - 40%.
gB
The oxygen economization factor of this device is particularly derived
from efficiency; however other factors are also relevant. This device has
an economization factor approx. 3 based on oxygen supply efficiency.
If further incremental economization of broad range of adjustment
complies with the patient's need and it is taken for the benefit of total
gas economization, the total gas economization factor can be about 4.8
(3x1.6).
