Product description
Spirolab is a portable spirometer that can also features a pulse oximeter feature (optional). The device can operate completely autonomously or can be connected to a personal computer or printer by means of USB or Bluetooth connections.
The device is intended for measuring respiratory parameters and monitoring oxygen saturation and pulse rate. The device carries out a control test on the quality of the readings taken and can save the results of about 10,000 spirometric tests or a maximum of 900 hours of oximetry data.
Spirolab is intended for use by medical specialists and it provides them with a powerful but compact tool that can process about 30 functional parameters. The device also provides a pharmacodynamic response, i.e. the % comparison of spirometric data measured before and after (PRE/POST) administration of a drug for bronchial provocation or bronchodilation. The POST data measured after administering the drug is compared with the PRE data obtained before administration.
A turbine inside the device that uses the interruption of infra-red light as its operating principle, measures volume and flow rate. This operating principle ensures accurate, reproducible results without needing periodic recalibration.
The key features of this type of sensor are as follows:
Accurate readings even with low air flow rates (end of exhalation)
Not affected by humidity and gas density
Unbreakable and shock resistant
Inexpensive to replace
The turbine volume and flow sensor is available in disposable and reusable versions.
REUSABLE TURBINE DISPOSABLE TURBINE
In order to preserve the characteristics of the turbines, it is important to observe the following precautions:
For the disposable turbine: always replace following patient spirometric tests
For the reusable turbine: always disinfect before use on a new patient to ensure the best possible hygiene and safety standards
To properly interpret the results of a spirometry test, it is essential to compare them with the so-called normality values that are calculated using standardised patient data or with personal reference values associated with that specific patient's clinical history.
An individual patient's clinical history values van vary significantly from normality values that always refer to a “healthy” subject.
Spirolab can be connected to a PC or another computerised system. The spirometric data from every test is stored in the device and can be transferred to a PC and displayed (flow/volume curves, spirometric parameters, oximetric parameters optional).
The device can be connected to a PC via a micro USB port.
Spirolab performs FVC, VC & IVC and MVV tests and the ventilatory profile, as well as an acceptability (quality control) and reproducibility index of the spirometry test carried out by the patient. The automatic interpretation function uses 11 levels as per ATS
(American Thoracic Society) classification. Every single test can be repeated. The best functional parameters will always be available for fast re-reading. The normality values (theoretic) can be selected from those available. For instance, in European Union countries. doctors generally use the values recommended by the ERS (European Respiratory Society).
Oximetry function
The oximetry sensor features two light emitting diodes (LED); one emits visible red light and the other infra-red. Both bands of light pass through the finger to reach a light detector. During the passage through the finger, some of the light is absorbed by the blood and
