When gentle asthma care is essential

Childhood asthma has been a difficult issue to address - until now.

The Ventica® System is a new paradigm for the assessment and

management of asthma in children aged five or younger.

Why Ventica® for children


Assessment of lung function is the cornerstone of both diagnosis and monitoring of asthma. Measurement of peak flow rate and spirometry are well-established techniques for older children and adults but are seldom suitable for young children due to the need for collaboration and motor coordination during a measurement.

Ventica® enables routine assessment of lung function in children for the first time. Even better, measurements are performed overnight while the child is sleeping at home in their own bed - under parental supervision and guidance.

Lung function assessment using Ventica® has been validated for children aged five and younger. Ventica® is a reliable method for pediatric lung function testing, with a measurement success rate demonstrated to be 90%.

Ventica® calculates variability in night-time tidal breathing
Ventica® lung function assessment is based on a novel application of impedance pneumography, indirectly measuring relative lung volume changes and derived flow rate profiles during breathing using a non-intrusive chest electrode configuration.

The Ventica® Recorder is set up by trained healthcare professionals. During an office appointment, a healthcare professional initiates measurement and educates parents on the use of the device. At home, parents place the electrodes near the child’s armpits. Alternatively, the electrodes can be placed by the healthcare professional during the office visit.


After gathering a full night’s measurement data, Ventica® is used to identify a child’s expiration phases during restful sleep. Proprietary software then calculates the correlation coefficients between all identified expiratory flow-volume curves. The final result of the analysis is the child’s Expiratory Variability Index (EVI®), a single number score which accurately and reliably indicates an individualised level of respiratory variability.

A child’s EVI® is associated with presence of lower airway obstruction and the clinical effects of asthma control medication on breathing. Importantly, the child’s EVI® reflects their natural “real- life” asthma status, as no external provocation is involved.

Components of the Ventica® System


Ventica® Recorder

The miniature Ventica® Recorder is a battery-operated device for recording and storing the impedance data acquired from the chest electrodes. After a night-time recording, the device is typically returned to the physician for data downloading, cloud-based automated data analysis and then clinical interpretation.

Ventica® Analytics Software

The Ventica® Analytics Software is designed for use by trained healthcare professionals. Intuitive and easy-to-learn, the software is used to control the Ventica® Recorder, to analyze the data and to manage the patient records.

Although the Ventica® Analytics Software is available as a cloud service, it can also be installed on a local Windows-based PC server.


Ventica® Electrodes

Ventica® Electrodes are single-use surface electrodes specially designed for use with the Ventica® Recorder. The electrodes feature skin-friendly adhesive and other materials to help ensure comfortable attachment and removal. The electrodes are color-coded for simple and verifiable attachment by a trained parent.

Ventica® Shirt

A Ventica® Shirt helps to keep the electrodes in place and supports the recorder while the child is asleep. The shirt has an inside pocket designed to keep the device out of reach by the child during measurement. Shirts are available in four sizes for a tight yet comfortable fit for most children. The material used in the shirts is ÖkoTex100 certified toxin-free.
