A CE marking has been granted for Revenio's asthma product Ventica®. This will enable the sales and marketing of the product, as well as clinical studies of broader scope in Finland and elsewhere in Europe. Ventica® is designed to assist in the diagnosis of asthma in small children in particular, as well as the evaluation of medication administered during treatment. Measurement of pulmonary function is an important part of treating asthma, but spirometry is unsuitable for children. Asthma symptoms tend to vary on an hourly basis. Ventica measures the patient's expiratory profile during the night, providing doctors with important information on the effectiveness of asthma medication.
