User manual
The device is specifically designed to measure a range of respiratory parameters and to monitor the saturation of oxygen in the blood
and the heart beat. A quality control check is carried out internally on the measured parameters and the device has an internal memory
sufficient for approximately 10.000 spirometry tests or at least 900 hours of oximetry monitoring.
Spirobank II
is a powerful and compact measurement device, intended for use by a respiratory specialist or by a suitably trained general
practitioner. The spirometer calculates up to 30 functional respiratory parameters providing the pharmacodynamic effects, i.e. the data
comparison after the administration of a drug (PRE/POST) for a bronchodilator test or for a 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 principle. This transducer ensures the
accuracy and the reproducibility of the measurements, without requiring periodic calibration.
The sensor features are listed below:
•
Accurate measurement even at very low flow rates (end of expiration)
•
Not affected by relative humidity and air density
•
Shockproof and unbreakable
•
Inexpensive to replace.
The turbine flow measurement sensor is available both in reusable and in single-patient disposable versions.
REUSABLE 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 from one patient to the other.
•
for the reusable turbine: always disinfect the turbine for testing from one patient to the next, to ensure the maximum level of hygiene
and safety.
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 II
can also be connected to a PC (or to another computerised system) to configure the instrument. All spirometry test data
including the related patient 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, plus optional oximetry parameters).
The connection to the winspiroPRO can be made via USB connection.
Spirobank II
can perform FVC, VC & IVC, MVV and breathing profile tests, and calculates an index of test acceptability (quality
control) plus the reproducibility of the spirometry tests carried out. The automatic test interpretation follows the latest 11 level ATS
(American Thoracic Society) classification. Each test can be repeated as required. The best parameters are always available for review.
The normal (predicted) values can be selected fr
om several normal “sets”. For example, within the European Union the majority of
doctors use the ERS (European Respiratory Society) predicted values.
Oximetry function (on request)
The oximetry sensor has two light emitting diodes (LEDs), one emits in the visible spectre and one infrared. Both lights then pass
through the finger and are “read” by the receiver. As these lights pass through the finger, a proportion of the light is abso
rbed by the
blood and by the soft tissue, in function of the concentration of heamoglobin. The quantity of light absorbed, at each frequency, depends
on the degree of oxygenation of the haemoglobin inside the soft tissue.
