The structure and gas kinematics of interstellar medium in irregular galaxies are regulated mostly by stellar feedback. Gas distribution in those galaxies represents a large amount of expanding shells and supershells in star formation regions. We performed the observations at 6-m SAO RAS telescope with scanning Fabry-Perot interferometer in H-alpha emission line and used the archival observations in HI 21 cm line in order to study the gas kinematics in individual star forming regions in several nearby dwarf irregular galaxies. We used available data in UV, optical and IR ranges to compare the gas structure and kinematics, the dust distribution and composition, and the properties of young stellar population in the regions studied. Here we present most interesting results of our investigations.
