What is an Aneroid Blood Pressure Monitor? How Does It Work?

Using an aneroid monitor, your blood pressure is manually checked. With a cursor on the dial, you can read its gauge. You inflate the cuff by hand by squeezing a rubber bulb around your upper arm.

It is not uncommon for aneroid monitors to be more affordable than digital monitors. They’re priced anywhere from $20 to $40, depending on the model.

A built-in stethoscope is included in the cuff. We already have one, so no need to purchase a new one. The cuffs can be put on using one hand if the device has that feature. It is also lightweight and portable, making it easy to move from one location to another.

Squeezable rubber bulbs and a gauge for taking blood pressure are all examples of manual devices. It’s necessary to use a medical stethoscope to hear the heartbeat.

The circular dial of the gauge shows your blood pressure as the needle moves and cuff pressure rises or falls.

When used properly, manual devices can be extremely precise. However, they aren’t the best option for people who want to monitor their own blood pressure at home.

How does it work?

A person can aneroid blood pressure monitor use it in the following ways:

  • Listen to what the stethoscope can hear. The ear buds should be positioned so that they face forward and away from your ears.
  • Place the stethoscope disc on your elbow’s inner side.
  • Squeeze the rubber bulb to inflate the cuff. As long as your systolic reading is 30- 40 points higher than the previous reading, you’re good to go. The systolic blood pressure reading is the highest number. Make sure to pump the cuff up quickly rather than slowly. A false reading will be obtained if the cuff is inflated too slowly.
  • Slightly loosen the unit’s valve and slowly release some air from the cuff. Remove 2 to 3 millimeters per second from the cuff. You won’t be able to take your blood pressure reading if you over-loosen the valve.
  • Once the cuff is deflated, you will hear your heart beating as you remove the air. When you hear something, pay close attention. Look at the needle on the dial to see if your blood pressure is within the normal range. This is your systolic pressure or the pressure in your arteries.
  • The cuff should be deflated further. Watch the rhythm of your own heart. At some point, you will hear the heartbeat stop. Take a look at the dial’s display. Your diastolic pressure is measured by this number.
  • Measure it and make a note of it in your book. It is the diastolic pressure that comes first. For instance, a 120/80 ratio
  • Wait 2-3 minutes prior to actually starting the measurement again if you do need to repeat it for any reason.

Tips for monitoring blood pressure

  • To ensure that you are taking your blood pressure correctly, practice using a monitor with the healthcare provider.
  • Your upper arm should be at the level of the heart and your feet should be on the floor so that your arm can be supported.
  • Before taking your blood pressure, sit down and relax for five minutes.
  • Stress, caffeine, or smoking in the last 30 minutes are all reasons not to take your blood pressure. If you’ve recently exercised, don’t take it.

Take at least two readings, one minute apart, in the morning and one minute apart during the evening. For the next five days, measure and record your BP, and then report the findings to your doctor.
