Electrical Impedance Tomography of Lung in Child and Young Age

Electrical Impedance Tomography of Lung in Child and Young Age

The investigator will determine a compliance of two diagnostic techniques (EIT and Body plethysmography) in collective of children and teenagers with obstructive lung disease and a matched control group.

The aim of the present study is verification of the correlation between EIT-derived data and following extracted parameters of the pulmonary function:

• forced expiratory volume in 1 second (FEV 1)
• forced vital capacity (FVC)
• relative forced expiratory volume in 1 second (FEV1/FVC)
• maximal expiratory flow (MEF 25)
• total lung capacity (TLC)
• resistance (Raw).

These findings could bring out new prospective opportunity for pulmonary function tests without cooperation.

Furthermore, the study aims to clarify whether EIT technique can be used for regional pulmonary function testing.

In addition, dynamic lung function parameter and static radiological techniques will be correlated with EIT.

Inclusion Criteria:

• Patients: children and teenagers with obstructive pulmonary disease (asthma, cystic fibrosis, immotile-cilia-syndrome, obstructive brochitis, obstructive pneumonia).
• Probands: Children and Teenager of 5-18 years without known obstructive pulmonary diseases

Exclusion Criteria:

• active implants (ICD, CRT)
• metal in chest
• artificial heart valve
• children < 5 years
• pregnant and lactating females
• Persons, who are in relationship of dependence to the investigator / sponsor
• Persons, who are not able to understand and follow the instructions of the study personnel.
• Lack of signed informed consent (by legal guardian /proband)
