to 100%, and set the calibration analyzer to oxygen
flow measurement.
12 Repeat steps 7 - 10. Record the reading on the Test Record.
Note: “The flow reading measured by the calibration analyzer”
mentioned in steps 7-9 shall be the actual analyzer measurement
dividing by 89%. This is because the e360 ventilator automatically
reduces the flow delivery by 11% of the set flow to compensate for
using without a humidifier (BTPS compensation).

to 21%, Flow to 30 L/min and VT (T

500; reattach the test lung.
NOTE: Because the e360 ventilator automatically compensates for
use with a humidifier by lowering the flow by 11% (calibrated to
BTPS) the calibration analyzer flow reading will be 11% lower than
the ventilator
’
s set flow rate if the calibration analyzer is not BPTS
compensated.
NOTE: When EMBED Equation.3 peakI reading displayed on the
Numeric screen is higher than expected flow, it could be caused by
the peak flow delivered in the very beginning of the inspiratory
phase. In this case, select flow waveform in the Waves screen, and
then press “Freeze” button to read the actual flow value. To adjust
the scale of the waveform, touch the flow axis on the screen, turn
the knob, and then touch the flow axis again to accept when a
proper scale is obtained.
