The easy way to diagnose pulmonary problems

The latest generation of Medikro dedicated software incorporates a number of technological innovations inPC-based clinical diagnostics. The fact that the capabilities of Medikro systems can be extended very easily asphysicians’ needs change makes them both user-friendly and cost-effective.

Asthma continues to be underdiagnosed, despite affecting close to 5% of adult Europeans and 10% of children in many countries. Medikro’s easy-to-use lung function analysis tools are doing their bit to remedy this situation and help give people suffering from lung complaints better treatment and improved quality of life.

Medikro’s spirometric measurement systems – based around the world’s smallest spirometer, the SpiroStar, a PC interface, proprietary software, and a disposable flow transducer – represent the state-of-the-art in the field. Weighing only 20 grams, Medikro’s spirometers can be connected to a standard USB or serial port to provide accurate and precise test results that are fully compliant with ATS, ERS, or ATS/ERS standards. A heuristic system algorithm monitors stability and guarantees repeatability and reliability.

Medikro’s patented disposable flow transducer has been designed for hygiene, convenience, and good throughput. Perhaps most importantly, it is capable of handling a wide range of flow rates, from the very low ones typical of children and patients with chronic obstructive pulmonary disease (COPD) to the high rates common among athletes.

No-compromise performance

Ease of use and flexibility were key priorities in the development of the latest generation of Medikro’s spirometry software, which has been designed to allow physicians to start off with a basic starter system and add features and capabilities as their needs change, without having to switch either the device or core software interface they use.

Medikro’s spirometric measurement systems – based around the world’s smallest spirometer, a PC interface, proprietary software, and a disposable flow transducer – represent the state-of-theart in the field.

SpiroStar Smart™ provides entry-level capabilities, while SpiroStar Pro™ and SpiroStar Sense™ offer additional performance; and all three comply with ATS/ERS 2005 requirements in terms of calculation criteria.

SpiroStar Smart™ is based on a simple, fourstep approach for doctors who need to perform screening tests, but value precision and accuracy and the ability to obtain common spirometry variables, such as FVC, FEV1, or PEF quickly. After entering a patient’s data, the physician can start measurement simply by pressing one button, stop it by pressing another, and then view the results. The reproducibility table provided by the software indicates whether manoeuvres need to be repeated or if the results can be accepted.

As its name indicates, SpiroStar Pro™ is intended for more extensive diagnostic needs, and a full suite of options is available to display and analyse data. The package retains the same intuitive user interface found in SpiroStar Smart™, smoothing the upgrade path.

Results can be analysed by viewing curves, examining numerical data, evaluating histograms, and checking bronchodilation response. Access to trending data helps assess patients’ response to treatment and how they are managing their condition.

SpiroStar Sense™ is the most advanced member of the family and offers both readyto- run bronchial provocation protocols and the possibility to create new ones based on existing ones or from scratch.

Select your protocol

Medikro’s bronchial provocation test, designed to evaluate the sensitivity of the airways in a person’s lungs, is a highly effective diagnostic tool, as it can help physicians diagnose a problem very precisely – whether they are general practitioners, pneumologists, paediatricians, or members of a hospital team.

A spirometry breathing test is carried out before and after spray inhalation, using methacholine or an environment-specific agent, to measure and compare how much air a person can breathe in and out, and how rapidly. The software includes default protocols for the most common types of tests used to diagnose asthma – histamine, methacholine, mannitol, and adenosine – as well as for exercise provocation and cold air provocation in the case of SpiroStar Sense™. Default protocols can be customised and new protocols stored for daily use.

When creating a custom protocol, challenge and bronchodilatator agents can be selected from a list of commonly used ones. Protocols can be imported and exported in XML format very easily, which enables testing to be carried out anywhere and the results sent to shared databases.

Easy for everyone

Medikro software is available in 14 languages, is easy to install, and provides a straightforward approach for selecting patient data entry, test recording, and data comparison. Capabilities can be upgraded simply by entering a software key.

The PC used by a Medikro system acts as a gateway for distributing results across a local area network. Open database connectivity (ODBC) makes it simple to communicate with other databases, such as hospital information systems; while the ability to email a ready-formatted or customised final report in html format, or a summary of a patient pulmonary function test session, to a colleague eliminates tedious paperwork.

Data from previous sessions can be reviewed in a trending screen to confirm the effect of treatment over time; while system calibration can be verified using calibration log data, simplifying quality control routines.

Graph: Ease of use and flexibility were key priorities in the development of the latest generation of Medikro’s spirometry software. Physicians can start off with a basic starter system and add features and capabilities as their needs change.
