More than 89% of aneroid readings and less than 44% of the readings by digital device had absolute difference of 5mm Hg. when compared with the mercury readings for both systolic and diastolic blood pressure. Sensitivity and specificity of aneroid device was higher (86.7% and 98.7%) than digital device (80% and 67.7%).
Why was mercury sphygmomanometer banned?
Mercury will no longer be permitted because it is toxic to the environment, and the replacement of the millimetre of mercury with the kilopascal, used throughout science as the unit of pressure, may be seen as an opportunity to tidy up an irksome anomaly in scientific nomenclature.
Which is the most accurate BP monitor?
Top 5 blood pressure monitors
- Omron Platinum. : Best overall.
- Lazle JPD-HA101. : Nurse recommended.
- Greater Goods BP Monitor. : Best for budget.
- LifeSource. : Best cuff size options.
- Withings BPM Connect. : Best app.
Are aneroid sphygmomanometers accurate?
In conclusion, a carefully maintained aneroid sphygmomanometer is an accurate and clinically useful means of indirect blood pressure measurement.
What is mercury sphygmomanometer?
Mercury sphygmomanometers are considered the gold standard. They indicate pressure with a column of mercury, which does not require recalibration. Because of their accuracy, they are often used in clinical trials of drugs and in clinical evaluations of high-risk patients, including pregnant women.
Is aneroid sphygmomanometer accurate?
What is the difference between a mercury and an aneroid sphygmomanometer?
Difference Between a Mercury & Aneroid Sphygmomanometer. A sphygmomanometer is a medical device for measuring blood pressure. It employs a cuff that attaches around the arm of the patient. Two main types include mercury, referring to the liquid element used for measurement, and aneroid, indicating the lack of any liquid.
Is the aneroid device more accurate than the digital sphygmomanometer?
Conclusion The aneroid device had better accuracy than the digital device as compared to mercury sphygmomanometer and should be used for proper and better management. Keywords: Blood pressure measurement, Digital sphygmomanometer, Hypertension, Receiver operating characteristics curve, youden index
Do digital and mercury sphygmomanometers measure the same blood pressure?
Among 108 pairs of data, average systolic measurement using digital (124.57 mmHg) and aneroid (124.31) is similar to mercury (125.01), there was no significant difference of average blood pressure measurement between digital and mercury sphygmomanometer (p= 0.71)]
Is mercury or digital blood pressure more accurate for aneroid?
Results: Data analysis of 218 study subjects showed the mean difference of the mercury reading and the test device was much less for aneroid than that of the digital device for both systolic and diastolic blood pressure.
