Recently while reading a newspaper, a small article caught my attention. It was written by a doctor from Mumbai regarding Blood pressure measuring apparatus.
Sphygmamanometer is the instrument which uses mercury as the prime element to measure the blood pressure of the patient. There are digital variants too but medical fatarnity still go by the golden standard of this sphygymeter.
The cause for concern is that these instruments need to be caliberated frequently. It seems the doctor has 5 different apparatus and each give different readings for the same patient immideatly.
So the doctor advices not to take high readings from one sphygmomonometer seriously and various readings from different doctors are consistently in the same band, you can be concluded to be hypersensitive.
The problem, doctor describes is more rampant in costal areas, where mercury expands and contracts due to pressure at costal regions. The same is true about our faithfull old thermometers measuring temperature..
So folks, take care about your BP and body temperature when measured by analog devices – they can be wrong too but dont ignore constant readings out of band.
