This report presents an analysis of the source of errors in the blood pressure measurements which use the oscillometric method. The basis of this method are the blood pressure oscillations in the occluding cuff which are used to evaluate systolic and diastolic pressures. They are found during calculations with the use of fixed constants. These numbers, having a statistical meaning, are the main source of a measuring error. The respective theoretical considerations are presented. Here they have been confirmed by the example of comparison of the measuring results obtained from two different blood pressure devices. During tests the instruments were connected together to the same occluding cuff A statistical method was used for evaluation of the results: the coefficient of variation and the reliability coefficient.
