Omron HEM-7121 Automatic Blood Pressure Monitor
How to measure blood pressure using a manual monitor-
Have your child rest their arm, palm facing up, where it will stay still. The Omron (HEM-7121) cuff will need to be placed at about the same level as the heart.
Put the cuff on a bare arm.
For a semi-automatic device:
- Manual, or aneroid, equipment includes a cuff, an attached pump, a stethoscope and a gauge.
- This equipment requires coordination. It's difficult to use if you're hearing or visually impaired or if you're unable to perform the hand movements needed to squeeze the bulb and inflate the cuff.
- When you're ready to take your blood pressure, sit quietly for three to five minutes beforehand.
- To begin, place the cuff on your bare upper arm one inch above the bend of your elbow. Pull the end of the cuff so that it's evenly tight around your arm. You should place it tight enough so that you can only slip two fingertips under the top edge of the cuff. Make sure your skin doesn't pinch when the cuff inflates.
- Once the cuff is on, place the disk of the stethoscope facedown under the cuff, just to the inner side of your upper arm.
- Next, place the stethoscope earpieces in your ears, with the earpieces facing forward, pointing toward the tip of your nose. Rest the gauge in the open palm of the hand of your cuffed arm so that you can clearly see it.
- Then, squeeze the pump rapidly with your opposite hand until the gauge reads 30 points above your usual systolic pressure. (Be sure to inflate the cuff rapidly). Stop squeezing. Turn the knob on the pump toward you (counterclockwise) to let the air out slowly.
- Let the pressure fall 2 millimeters, or lines on the dial, per second while listening for your heart sounds. Note the reading when you first hear a heartbeat. This is your systolic pressure.
- Note when you no longer hear the beating sounds. This is your diastolic pressure.
- Rest quietly and wait about one to two minutes before taking another measurement. Record your numbers either by writing the information down or by entering the information into an electronic personal health record.
- To monitor your blood pressure using an automatic blood pressure monitor, find a comfortable place to sit with good back support at a table or desk.
- When you're ready to take your blood pressure, sit quietly for three to five minutes beforehand.
- Place your feet flat on the floor and rest your arm on a tabletop even with your heart. Lean against the back of the chair. Stretch out your arm, palm upward.
- Place the cuff on your bare upper arm one inch above the bend of your elbow. Make sure the tubing falls over the front center of your arm so that the sensor is correctly placed. Pull the end of the cuff so that it's evenly tight around your arm. You should place it tight enough so that you can only slip two fingertips under the top edge of the cuff. Make sure your skin doesn't pinch when the cuff inflates.
- To get started, wait a moment, then press start. Remain still and quiet as the machine begins measuring. The cuff will inflate, then slowly deflate so that the machine can take your measurement. When the reading is complete, the monitor displays your blood pressure and pulse on the digital panel. If the monitor doesn't record a reading, reposition the cuff and try again. Rest quietly and wait about one to two minutes before taking another measurement.
- Record your numbers, either by writing the information down or by entering the information into an electronic personal health record. Some monitors can upload your blood pressure readings automatically into a computer or mobile device.
Have your child rest their arm, palm facing up, where it will stay still. The Omron (HEM-7121) cuff will need to be placed at about the same level as the heart.
Put the cuff on a bare arm.
- The bottom edge of the cuff should be about 1 inch above the bend in your child’s elbow.
- Find the symbol or arrow on the edge of the cuff to know where to position the cuff over the artery.
- Wrap the cuff snugly. The tube(s) should hang freely toward your child’s body.
For a semi-automatic device:
- Before putting on the cuff, make sure that there is no air in it. You may need to push an air release button near the bulb to let out the air.
- Put the cuff on and squeeze the bulb quickly to fill (inflate) it with air. The cuff should inflate to a number at least 30 higher than the expected systolic pressure. If your child is taking their own Omron (HEM-7121), they should grasp the bulb with the hand opposite the arm the cuff is on.
- The cuff will become tight and hurt a little, but only for a few seconds.
- The machine will beep to let you know when the cuff is inflated enough. After you hear the beep, press the air release button, and lay down the bulb. Have your child relax and sit quietly. The device will do the rest of the work.
- As the device slowly lets air out (deflates), you will see numbers change and a flashing arrow pointing down. When the device senses a pulse, a heart symbol in the display starts to flash. You will hear a beep for each heartbeat.
- When done, the display will show the systolic and diastolic blood pressures and the
- heart rate.
- If the machine was not able to take the Omron (HEM-7121), the display would show a flashing arrow pointing up. You will need to start over. This time, pump the bulb a little higher than
- 30 above what you think the systolic pressure will be. Remind your child to sit still.
- After you press the START button, the cuff will fill with air. The device can sense how much to inflate the cuff. It will become tight and hurt a little, but only for a few seconds.
- As the device lets air out, you will see numbers and a tiny heart symbol flashing. The flashing heart is your child’s heartbeat.
- When done, the display will show the systolic and diastolic blood pressures and the heart rate.
- If your child moved or if the cuff was not put on right, the device may show an E or error message. When this happens, repeat steps 1 and 2.
- It is important to keep a record of your child's blood pressure. Use the Blood Pressure Record or write the readings down on a calendar. Take the record with you whenever your child sees their doctor or health care provider.
