Measure the pressure on the reliable old-fashioned

It's only in small provincial hospitals can meet hand-held devices for measuring pressure, they are also still used by doctors with extensive experience. But the latest electronic pressure gauges often lies as established researchers.

Experts from Good Samaritan Hospital in Los Angeles, decided to conduct an experiment and compare the results measuring blood pressure Holding an old hand and new electronic devices. It turned out that the new technique consistently lowers indicators, at least two or three points. However, in the age group of patients over 65 years these differences were even higher, although it is for such people the most important thing to know exactly its pressure.

Old auskultatsionny method (from the Latin word meaning "listening) measuring blood pressure using a stethoscope and a mercury manometer. The stethoscope is placed on the artery of the patient, allowing the physician or nurse to hear sounds when return pulse (systolic blood pressure) and then disappear again (diastolic pressure), while the arm cuff is inflated and deflated, the blood flow flowing in the artery.

New electronic device calculates systolic and diastolic pressure on the basis of the average pressure in the artery. Oscillometric measuring blood pressure It requires less skill than the previous auskultatsionnaya system, so a similar device can manage, and untrained people. One needs only to press the button.

At the moment, the majority of doctors and medical centers refused to older devices, but the study found that the accuracy is still superior, and sometimes very significantly, evidence of new instruments. Earlier, there were conflicting views on this matter, but US scientists have conducted rigorous research by measuring the pressure of the same patient is connected to a cuff at a time old and new instrument for measuring pressure.
