Objective: This study aimed to determine the reliability of automated and manual blood pressure measurement devices.

Methods: Descriptive and methodological study was determined in 110 patients admitted to the intermediate coronary intensive care unit whose blood pressures were measured via automated and manual sphygmomanometers. An invasive measurement value (arterial catheter) compared the other findings. The data were analyzed by using descriptive, Pearson’s correlation analysis, independent t-test, and one-way variance analysis. 

Results: Of the patients included in the study, the mean age was 67.77 ± 11.66 years, the mean BMI was 27.74 ± 4.45 kg/m2, and the mean mid-arm circumference was 27.51 ± 2.48 cm. The systolic blood pressure readings obtained by all modes of blood pressure measurements in all lying down positions of the patients were found out to be in “perfect” agreement with the blood pressure readings obtained via an arterial catheter for the systolic blood pressure measurement. There was a “moderate” level of agreement between the diastolic blood pressure measurements obtained via an arterial catheter, and the readings were obtained by a manual device. There was a “poor” level of agreement between the diastolic blood pressure measurements obtained via an arterial catheter, and the readings were obtained by an automated
device. It was observed that the differences between the blood pressure values obtained by using an arterial catheter and other blood pressure devices were significant in all lying positions of the patients (P < .05).

Conclusion: The level of agreement is high across systolic blood pressure measurements obtained via different blood pressure devices; however, it is observed that the level of agreement across diastolic blood pressure was lower.
