Comparison of Blood Pressure measurements taken by one stage approach, two stage approach and digital apparatus

Mercury sphygmomanometers was developed over 100 years ago and largely unchanged since used in both hospital and ambulatory settings and considered as gold standard device for accurate blood pressure measurements.Blood pressure is important diagnostic index for circulatory function.If Blood pressure is abnormally low or high, it usually indicates greater health problem exist i.e. heart disease or stroke.So the aim of study was to compare blood pressure recordings taken with one stage approach, two stage approach and digital BP measurements among Healthy people.It was a survey approach and comparison design study were conducted and study protocol was approved by Institutional Ethics Committee.Healthy people were enrolled with total enumeration technique.Total 131 healthy people BP measurements taken with one stage, two stage approach and digital BP apparatus.Mean and SD of systolic (66.27±6.9)and diastolic (107.92±9.4)BP measurement obtained by one stage approach was similar to measurement obtained by digital BP apparatus whereas Mean & SD of systolic (55.15±6.71)and diastolic (103.52±9.23)BP measurement obtained by two stage approach are different.Systolic & Diastolic BP measurement taken by one stage approach and digital BP apparatus were similar and interchangeable and with two stage approach measured signifi cant difference indicate measurement may not be accurate.
