Every action has an equal and opposite reaction: the more firmly the cuff applies pressure to the arm, the stronger the blood will push against it as it moves through the vein, meaning a clearer reading. If the cuff is too loose and is not applying pressure, it won't be able to read pressure very well.
I would suggest purchasing a smaller one or tighten it if possible. If not, I'm sure your local drug store could help you with taking your BP free of charge.
You need to get a new one or you Will hurt if you dont
then blood pressure will read low.
It may be inaccurate.
error in blood pressure measurement
The medical term for a blood pressure cuff is a sphygmomanometer.
To take someone's blood pressure you will need a blood pressure cuff and stethoscope. Have the person place their arm on a table, with their feet flat on the floor. Put the blood pressure cuff around their arm, snug but not tight, about an inch above the bend of the elbow. Place the stethoscope in the center of the bend of the elbow, tighten the knob on the pump, then inflate the cuff to around 180. Loosen the knob slightly in order to slowly release the air from the cuff and listen carefully. When you begin to hear the heartbeat through the stethoscope, that is the systolic blood pressure. When you cease to hear the heartbeat, that is the diastolic blood pressure.
A device to check your blood pressure manually. (Blood pressure cuff)
A blood pressure cuff is a sphygmomanometer. Better check the crossing word in the puzzle :)
When the blood pressure cuff is inflated, the blood flow is stopped. Slowly the cuff is decreased. When the technician starts to hear the blood flow, these are called Korotkoff Sounds. This pressure point defines the systolic pressure.
The pressure in the cuff drops further, the sounds change in quality, then become muted, then disappear altogether. As the pressure in the cuff drops below the diastolic blood pressure, the cuff no longer provides any restriction to blood flow allowing the blood flow to become smooth again with no turbulence and thus produce no further audible sound.
The real name for a blood pressure cuff is sphygmomanometer.
systolic/diastolic measured by blood pressure cuff
At an exam with your doctor, they will put a cuff on your arm and inflate it just enough to feel the pressure, then the cuff is let go to deflate. The time it takes for your body to deflate that cuff counts as your blood pressure, counted by the doctor or nurse you will see.
If an automatic blood pressure cuff will not register your blood pressure, it is probably broken. If you don't think that is the reason. you should consult your physician and ask he/she to take it for you. If it still does not show up, then you may want to discuss with the doctor why it does not show.
