Spiro-Spectrum General Properties 

Digital spirometer Spiro-Spectrum is the result of four year NeuroSoft Company researchers' and engineers' work. The device is intended for diagnostics of pulmonary ventilation capability disorders. It gives an opportunity to execute the following tests:

·                   Forced expiration. It has the greatest diagnostic value since it enables to examine up to 30 pulmonary ventilation capability parameters. The software supports the specific test execution mode for screening checkups.

·                   Inhalation tests. Bronchodilatation and provocation tests help to assess respiratory airway obstruction reversibility and hypersensitivity.

·                   Quiet breathing. Vital capacity and inspiratory reserve volume are measured in this mode.

·                   Maximum pulmonary ventilation capability. Breathing frequency and minute volume are also measured. It can be applied both for hyperventilation and for quiet respiratory minute volume measuring.

Measurement Parameters:

VC test: VC, IRV

FVC test: FVC, FEV0.5, FEV1, FEV3, FEV1/VC, FEV1/FVC, FEV3/VC, FEV3/FVC, MEF25%, MEF50%, MEF75%, MEF25-75%, MEF75-85%, MEF0.2-1.2l, Aex, PEF, Tex, TPEF, VPEF, IVC, FIV0.5, FEV0.5/FIV0.5, PIF, FIF50%, FEF50%/FIF50%

MVV test: MVV, BF

Two digital amplifier stages are involved in the measurement process (the first one is for low flow rates, the second is for high ones). Amplifier stages are switched by software. It provides the high measurement accuracy in the wide range of flow rates.

Availability of built-in atmosphere pressure and temperature sensors frees the user from inserting the data manually. The parameter values are brought to BTPS standard.

The software supports operation with formulas of due values by Clement and Knudson, by ECCS and ITS standards; as well as enables to specify your own formulas. Moreover, you have an opportunity to generate the report with disorder type and intensity indication automatically.

The unit and its software are developed according to RF Health Ministry and American Thoracic Society (ATS) recommendations on techniques of ventilation apparatus functional examination.

Spiro-Spectrum Techniques 

 

 

 

 

 

Quiet Breathing.

The main measured parameter is vital capacity (VC). Moreover, inspiratory reserve volume (IRV) is also measured. Except spirograms real-time displaying is provided in all types of tests.

 

 

 

 

 

 

 

Forced Expiration.

This is the most important type of test in point of diagnostics. More than 25 parameters of pulmonary ventilation capability are calculated (FVC, FEV1, PEF, MEF25%, MEF50%, MEF75%, etc.). The parameters are fundamental for medical report generation.

 

 

 

 

 

 

 

Maximum Pulmonary Breathing Capacity.

During the test a patient breathes extremely deeply and frequently through the unit for a short time. Breathing frequency (BF) and minute ventilation (MVV) are calculated.

 

 

 

 

 

 

 

Inhalation Tests.

The software has an opportunity for inhalation test report generation providing necessary comparison of received parameters with the convenient presentation of data. Software also automatically determines whether the test result was positive or negative.
