We analysed the ionized gas kinematics of the dwarf galaxy NGC 4214 using high resolution Fabry-Perot interferometry observations and present a set of narrowband images in the Hα, [S II] λ6717 Å, [N II] λ6584 Å, and [O III] λ5007 Å emission lines. The high-resolution Fabry-Perot observations of the Hα emission line, allowed us to derive the velocity field, the velocity dispersion σ, and the rotation curve of the galaxy. We also present for the first time, 3D kinematic maps of the complexes NGC 4214-I and NGC 4214-II and analysed the kinematics of the ionized gas of two new superbubbles, as well as the supernova remnants previously detected in this galaxy by other authors, in radio, optical, and X-ray emission. We computed the expansion velocities of the superbubbles and supernova remnants fitting their velocity profiles and obtained their respective physical parameters. We found that the superbubbles have an expansion velocity of ∼50 km s ^–1, dynamical age about ∼2 Myr and wind luminosity L_W of ∼9 × 10³⁸ erg s^–1 produced probably by massive stars in OB associations. For supernova remnants, their expansion velocities are between ∼48 and ∼80 km s^–1 with ages of about 10⁴ yr and kinetic energy of about 10⁵¹ erg assuming they are in the radiative phase of evolution.
