Abstract
In this study, we evaluated the performance of aneroid sphygmomanometers dials under specific temperatures. Five different Sphygmomanometer dials were placed inside the chamber. The dials were kept in the chamber with five different temperature settings for 1 hour, and the pressures were applied to the dial from 0 to 300 mmHg and vice versa. The result shows that the performance of all the dial models based on a one-factor analysis of variance has shown that the parameters have significant effect. The first variable affecting the performance is the pressure and model. Based on the GR&R using the ANOVA method, the total GR&R based on % Combination Variance is 67.87% and % Study Variance is 82.38. The most significant sphygmomanometer dial model that affected the treatment is model C. This study indicates that based on IEC 80801 or by the GR&R, there are potential measurement consistency and accuracy issues, so the manufacturer requires some investigation and corrective action.
