bronchial challenge test. A comparison of data is made between POST (after-drug) and PRE
(before drug administration).
The flow and volume measurement sensor is a digital turbine, based on the infrared
interruption principal. This principal ensures the accuracy and the reproducibility of the
measurements, without requiring a periodic calibration.
The features of this kind of sensor are listed below:
• Accurate measurement even at very low flow rates (end of expiration)
• Not influenced by gas humidity nor density
• Shockproof and unbreakable
• Inexpensive to replace.
The turbine flow measurement sensor is available both in reusable and in single-patient
disposable versions.
REUSEABLE TURBINE DISPOSABLE TURBINE
The following precautions must be observed to ensure that the characteristics of the turbine
remain unaltered over time:
• for the disposable turbine: must always be substituted between patients.
• for the reusable turbine: always clean the turbine between patients, to ensure the maximum
level of hygiene and safety for the patient.
For a correct interpretation of a spirometry test, the measured values must be compared
either to the so-called normal or predicted values which are calculated from the
anthropometric details of the patient or, alternatively, to the personal best values from the
clinical history of the subject.
The personal best values can vary considerably from the predicted values, which are taken
from “healthy” subjects.
spirobank G can also be connected to a PC (or to another computerised system) to configure
the system. All spirometric test results plus the related subject details stored inside the device
can be transferred from the device to the PC and then viewed on the PC (Flow/volume
curves, spirometry parameters).
The connection to the PC is made through the USB port or the Bluetooth.
spirobank G gives an automatic interpretation of each spirometry test carried out, and assigns
a “traffic light” feedback (green, yellow or red) for a rapid reading of the interpretation.
spirobank G is able to make FVC, VC, MVV and breathing profile tests, and calculates an
index of test acceptability (quality control) plus the reproducibility of the spirometry tests
