Features of the Product
OMRON IntelliSense™ Blood Pressure unit, Model HEM-907 is developed to measure blood
pressure and pulse rate accurately and simply in a doctor's office, examination room, or patient
bedside.
• One-button operation
Simply wrap the cuff and push the START Button. Blood pressure and pulse rate are automatically
measured by the oscillometric method.
• Automatic pressure setting
When the P-SET (Pressure Setting) Knob is set to "AUTO," the unit will automatically inflate the
cuff to the optimal pressure according to each patient's blood pressure. Pre-setting inflation level is
not necessary.
• Noiseless operation
This unit operates so quietly that it can be used in the patient room at night.
• Average Mode (AVG Mode)
In the AVG Mode, this unit will automatically measure for two or three times. The average of
systolic and diastolic blood pressures and pulse rate are displayed. Each measurement can also
be shown individually. The number of measurements, waiting time before first measurement, and
the interval can be changed.
• Auscultation Mode (MANU Mode)
You can measure auscultatory blood pressure by using a stethoscope, with automatic cuff inflation
and deflation by this unit. Because the cuff pressures during deflation are displayed digitally and
synchronized with the heart beat, they can be read with accuracy. After taking systolic reading you
can accelerate cuff deflation to shorten measurement time.
• Large and easy to read display
Large and easy to read figures are displayed on the LCD display.
INTELLISENSE™ blood pressure monitor is a global brand name of blood pressure monitor
equipped with bio-information sensing and high performance fuzzy logic technology, which are
the key technologies of OMRON. With this excellent sensing technology, the monitor can
achieve “accurate” and “fast” measurement.

Features and Functions
Functions setting
(1) Inflation level setting
AUTO (Automatic setting): Can be used when the SINGLE, AVG, or MANU Mode is selected.
The unit estimates the systolic blood pressure during inflation and inflates to a proper cuff pressure
(approximately 30-40 mmHg above the patient’s systolic pressure).
Manual level setting: Inflation level can be set manually between 100 and 280 mmHg. Set the
level to 30 to 40 mmHg higher than the expected systolic pressure.
• To set the P-SET to "AUTO," turn the P-SET Knob counterclockwise as far as it goes until you can hear a click.
• In the "AUTO" setting, inflation level may not be set automatically when the systolic blood pressure is more than
220 mmHg. Use the unit in the manual setting.
• If the cuff has not been inflated to the necessary level, it may be re-inflated automatically.
(2) Non-display function
Use to prohibit the display of measurement results. However,
the cuff pressure during measurement is displayed.
This function can be used in the SINGLE and AVG Modes.
By pushing the Button, display or non-display of status
is switched alternatingly.
(3) Manual deflation control
Accelerate deflation by pushing the DEFLATION (deflation
control) / Measurement Result Display Switch Button during
deflation in the measurement by the MANU Mode.
With each push of the Button, cuff is deflated rapidly
in increments of 5 to 10 mmHg.

How to Apply the Cuff
General advice
• Do not inflate the cuff without being wrapped over
the arm.
• Do not use a damaged cuff.
1. Select the cuff according to the arm size
Arm circumference Name of the cuff
(7” - 9”) 17-22 cm HEM-907-CS19(Small)
(9” - 13”) 22-32 cm HEM-907-CR19 (Medium)
(13” - 17”) 32-42 cm HEM-907-CL19(Large)
• Check the following before applying the cuff:
1) The bladder is correctly installed in the cuff.
2) The bladder is not twisted inside the cuff.
3) The bladder tube is protruding from the cuff as shown in
the Figure on the right.
2. Connect the air tube securely.
• Connect the air tube to the main unit by securing
the air plug to the base of the air connector.
• Securely connect the air tube and the cuff/bladder
set by rotating the luer connection as shown in the
Figure on the right.
Do not wrap the cuff over on arm to which
intravenous injection or transfusion is being
conducted, or when otherwise contraindicated.
Do not connect the air tube or the cuff to other
equipment which is connected to intracorporeal
organ. Air embolisms may result.
The cuff of OMRON IntelliSense™ Blood Pressure Monitor HEM-907 plays an important role of
collecting the information on blood vessels. Please wrap the cuff according to the procedure, below.

patient's arm circumference and wrap it again.
• Wrap the cuff so that you can insert only one finger between the cuff and arm.
7. Keep the level of the cuff at the same
level as the heart during the
measurement.
3. Place the hand of the patient with the
palm of hand facing upward.

How to Check Pressure Accuracy (CHECK Mode)
Accuracy of pressure display can be checked in the CHECK Mode.
What you need to prepare
(1) Calibrated mercury manometer (including inflation bulb), (2) T-tube, (3) two air tubes, and (4) a
sturdy cylindrical shaped object on which the cuff is wrapped.
Check result
Accuracy of the monitor is controlled by ±3 mmHg or 2% of standard manometer reading. If your result
shows a difference exceeding the tolerance, contact Omron repair department (1-877-216-1336).
How to check
1. Connect the manometer,
inflation bulb, cuff, and the
monitor with the T-tube as
shown in the figure on
the right.
2. Tightly wrap the cuff over a
sturdy cylinder.
3. Release the valve of inflation
bulb to remove the air inside
the cuff completely.
4. Push the ON/OFF (power) Button to turn on the monitor.
5. Set the MODE Selector to “CHECK”.
6. Close the valve of inflation bulb and inflate the cuff to the
pressure to be checked, based on the manometer read.
7. Compare the pressure values displayed on the monitor to
the one on the manometer.

• This is a trouble of the main unit of the
monitor.
How to correct
• Confirm that the air tube connecting the cuff and
the main unit is connected securely.
• Confirm that the air flow in the air tube
connecting the cuff and the main unit isn’t being
restricted.
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Check bladder for leaks and, if necessary,
replace the bladder with new one (option).
• Confirm that air flow in the air tube connecting
the cuff and the main unit isn’t being restricted.
• If the measurement is made by setting the PSET to "AUTO", ask the patient not to move
during the inflation.
• Confirm that the P-SET is securely set to
"AUTO". Turn the Knob counterclockwise as far
as it goes until you can hear a click sound.
• If the measurement is made by manual inflation
level setting, set the value to 30 to 40 mmHg
higher.
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Ask the patient not to move during the
