Asthma Monitor

The "Asthma Monitor" program is designed for daily monitoring of PEF and FEV1 in a hospital setting.

Advantages

- the monitoring chart is available both on the device screen and in the printed protocol.

- diagnostically significant cases with an excess of the norm of daily variability of PEF and FEV1 are automatically reported.

Based on the accepted children’s and adult tests-questionnaires on asthma control, an asthma control score with interpretation is also displayed in the printed protocol.

Monitoring data is stored in the non-volatile memory of the device and can be used as needed, for example, during repeated hospitalization to select pharmacotherapy.

The program “Asthma Monitor” can be installed in any spirometer MAS-1-A, except for the model with a monochrome screen.

 

SpiroExpert

“SpiroExpert” provides the performance of tests of VC, FVC, MVV, bronchodilatory, provocative tests, as well as tests with physical activity with the measurement and calculation of over 40 parameters of ERF.

Expert system "SpiroExpert is the basic software of spirometers MAS-1-A:

• calculates the criteria of technical acceptability and quality of tests under ATS/ERS-2005 download pdf...;
• in the interactive mode (as prompts and messages on the device screen and in the study protocol) it informs about the diagnostic significance of each test, as well as about the order of further performance of respiratory maneuvers;
• notifies of technically acceptable/unacceptable test execution;
• evaluates the reproducibility of tests under ATS/ERS-2005;
• automatically selects the best attempt out of all completed;
• issues a preliminary conclusion on the patient's ERF with an indication of the type and degree of violation of lung ventilation;
• automatically interprets bronchodilation tests with the calculation of the reversibility of bronchoobstructive syndrome;
• automatically interprets bronchodilation tests with the allocation of the severity of COPD;
• regulates the procedure for performing provocative tests according to a protocol that allows for up to 8 studies (initial, with saline and up to 6 dilutions of bronchoconstrictor) with the calculation of bronchoconstriction and issuing a recommendation to discontinue the test;
• implements special functions for storing and processing information
• allows you to interpret the patient's examination protocols at a glance: without analyzing the numerical values of the ERF parameters ;

Implements an animation test that allows increasing the motivation of younger children (starting from 4 to 5 years old) in the correct execution of tests.

After conducting a routine study of the ERF of a patient who has been examined on this device, the expert system will not only form a regular ERF protocol but also analyze the dynamics of ERF indicators for the entire follow-up period under the diagnostic criteria of COPD.

Having detected a situation characteristic of COPD, according to one or more analyzed parameters, including HF, the expert system MAS-1-A will post a corresponding message in both electronic (on-screen) and printed versions of the examination protocol.

Thus, with regular examinations (for example, during medical examinations, annual occupational examinations of persons working in hazardous industries), there is an opportunity for preclinical diagnosis of COPD with the allocation of respiratory risk groups among the population.

 

The animation test for the MAS-1-A spirometer

The expert system of the spirometer MAS-1-A presents to the patient’s attention the animated test: a “live” picture that reacts to the patient’s breathing efforts.

It is preferable for younger children with imaginative thinking who do not understand the instructions of the medical staff on performing breathing maneuvers enough. Besides the instruction: “Imagine a birthday cake with a lot of lighted candles on it. Take a lot of air and exhale hard, hard. Try to blow out more candles ...” - You simply offer the child to look at the screen (monitor) of the spirometer and exhale to blow out the maximum number of candles. The more candles the patient “blew out”, the more reliable the data of the tests will be, and the result of the maneuver will be intuitively understandable to the child.

The experience of using the animation test in the expert system of the spirometer MAS-1-A has not only confirmed its effectiveness when working with children but also revealed new possibilities of performing spirometry for people with hearing loss, sometimes being the only possible way to perform a study of ERF in such patients.

The animation test also proved to be very effective in conducting mass screening studies of ERF, including professional examinations.
