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 soft tissue depending on the concentration of haemoglobin. The amount of each light
frequency absorbed depends on how oxygenated the blood is inside the tissue.
This operating principle ensures accurate and reproducible readings without the need to
constantly calibrate the device.
The oximetry sensor can be disinfected with Isopropyl alcohol.
