Part Description
3.8
The flow and volume measurement is carried out as follows:
Volume
It is proportional to the number of pulses detected by the receiver diode during
expiration (expired volume) or inspiration (inspiratory volume);
Flow
the absolute value of the flow (positive for both expiration and inspiration) is
proportional to the inverse of the pulse width detected by the receiver diode;
IN/EX
The flow direction is detected by verifying which pulse (rx1, rx2) is received first. The
turbine doesn't need to be calibrated daily as it is not affected by pressure, humidity and
temperature.The turbine should be maintained with regular ordinary sterilization to move freely
without friction, free of dust.
