Coude spectra of the helium-variable HD 184927 are analyzed. Equivalent widths of selected lines and radial velocities were measured. We discuss the variation of these parameters for some lines and we redetermine the period of variation. The main characteristics of the atmosphere of HD 184927 are computed and all the available information is discussed within the framework of the oblique rotator model.
