Blood pressure (BP) is a vital parameter of utmost importance in the medical routine of small animals, through which it is possible to have a general notion of the hemodynamic status of patients. BP can be measured directly, using invasive pressure measurement, considered the standard, or indirectly using vascular Doppler or pulse oscillometric devices. With the emergence of new noninvasive pressure measurement methods, the invasive pressure technique becomes a viable, practical, and inexpensive alternative for comparing methods to verify the accuracy of noninvasive indirect procedures. Thus, this study aims to evaluate the high definition oscillometric (InCardio) accuracy during anesthetic maintenance in cats submitted to ovariosalpingohysterectomy and orchiectomy. Invasive Blood Pressure is the “gold standard” method for measuring blood pressure, performed through arterial catheterization. Since this technique provides greater accuracy of BP values. The differences between the method of measuring blood pressure to be evaluated high-definition oscillometric (PASOAD) in relation to the invasive methods (PASinv) will be analyzed using the Bland-Altman method and compared using Student's t test. In this study, 7 cats were evaluated, all mixed breed (SRD) weighing between 2.5 kg and 5 kg. A total of 9 pressure measurements were established with an interval of 30 seconds between each measurement by both methods for each patient. In cats, the High Definition Oscillometric method (InCardio) does not show good agreement with the invasive pressure measurement method. After the statistical analysis using the Bland-Altman method, it was found that the Systolic Blood Pressure had a bias of 15.3 mmHg, indicating an overestimation of at least 15 mmHg by the HDO method in relation to the other technique. Furthermore, the standard deviation of 18 mmHg exceeds the criterion established by the ACVIM of 15 mmHg, evidencing a lack of agreement between the SBP values obtained by the two methods
