Good night. I want to ask about tensimeter if the needle is not at zero point does it affect the results if used for attention? Because the tension point of the needle that I used was not a needle point at zero but a 300 point needle. Thank you

Hello Anggi Nawang Wulan,


Tensimeter is a blood pressure measuring device. Now there are many choices of tensimeter, ranging from mercury tensimeter, needle tensimeter, and digital tensimeter. Needle gauge is one of the blood pressure checks manually. The tensile needle / aneroid tool consists of several parts namely:

Rectangular cuffs that are generally wrapped around the arms
Pressure gauge - there are moving needles that show certain numbers (blood pressure results in mmHg units)
Pump balloon
The hose that connects the cuff to the pressure gauge
The hose that connects the cuff to the pump

Needle gauge has the advantage of mercury tensimeter, which is easier to carry everywhere. However, it is necessary to periodically calibrate the needle tensimeter so that the measurement results remain accurate. The measurement method must also be correct, namely:

The patient sits or lies down, with arm height measured by heart
Instruct the patient to rest about 5 minutes before measurement
Remove the air from the cuff / must be completely deflated
Place the cuff on the upper arm, 2-3 fingers fold from the elbow. Attach the cuff is not too tight and not too loose, usually there are markers / lines that indicate it must be placed in the brachial artery
Place the stethoscope under the cuff in the area of ​​the brachial artery (inside side of the arm)
Make sure the needle starts at 0
Turn the knob on the pump until it is closed and no air flow is out
Non-pumping fingers feel the radial arteries
Pump the balloon until the radial artery is not palpated, then the pump to add pressure of about 20 mmHg again
Turn the knob slowly so that the pressure on the meter decreases slowly
Listen to Korotkoff's voice from the stethoscope and record the measurement results of the systole diastole

If the needle of the tensimeter that you are using does not start with the number 0 it will certainly affect the results of the examination. It is recommended that you recalibrate the device before reusing it. Thus the explanation from me, hopefully useful.
