Preparing to Take Measurements
9650-1214-01 Rev. G 9
Note: The following procedures assume that you are
already in the NIBP menu.
Selecting Cuff Inflation Settings
Before taking a measurement, ensure that the cuff
inflation settings are appropriate for the patient. To
measure a patient’s blood pressure, the cuff begins the
measurement cycle by inflating to a pressure higher than
the patient’s systolic blood pressure. This value is called
the cuff inflation pressure. During an NIBP
measurement, the E Series unit may increase the cuff
inflation pressure over the initial value to obtain a systolic
reading.
By default, the cuff inflation pressure for the first
measurement after power-up is set to 180 mmHg
(24.0 kPa).
Use the default setting unless it is clearly inappropriate.
Any changes to this setting remain in effect until either
the setting is changed or 10 seconds after the E Series
unit is turned off (returning the setting to its default).
As a safety feature, the cuff can never be inflated to more
than 300 mmHg (40.0 kPa).
Setting Cuff Inflation Pressure
Before taking a measurement, check that the cuff
inflation pressure is appropriate for the patient. The cuff
inflation pressure options are:
• 120 mmHg (16.0 kPa)
• 140 mmHg (18.7 kPa)
• 160 mmHg (21.3 kPa)
• 180 mmHg (24.0 kPa)
• 200 mmHg (26.7 kPa)
• 220 mmHg (29.3 kPa)
• 240 mmHg (32.0 kPa)
• 260 mmHg (34.7 kPa)
See the E Series Configuration Guide for information on
reconfiguring the cuff inflation pressure default setting.
To set the cuff inflation pressure:
1. Press the Cuff Inflation softkey from the NIBP menu.
If the Cuff Inflation softkey is not displayed, see
“Displaying the NIBP Menu” on page 8.
The E Series unit displays the Cuff Inflation menu:
2. Press the Next softkey if “Inflation Pressure” is not
highlighted.
3. Press the Inc or the Dec softkey to select cuff
inflation pressure.
4. Press the Return softkey to return to the NIBP menu.
The cuff inflation pressure is set.
Auto Adjust
The E Series unit automatically adjusts the cuff inflation
pressure for all subsequent measurements to 30 mmHg
(4.0 kPa) greater than the systolic value of the previous
measurement. This default setting is called Auto Adjust.
For example, the cuff inflates to 180 mmHg for the first
measurement and the unit obtains a systolic reading of
110 mmHg. For the next measurement, the cuff inflates
to 140 mmHg (i.e., 110 + 30 = 140).
If the Auto Adjust feature is set to OFF, the selected cuff
inflation pressure is used for all measurements. If the
Auto Adjust feature is set to ON, the selected cuff
inflation pressure is used for the first measurement only.
Turning Off Auto Adjust
You should turn off the Auto Adjust feature in situations
where the E Series unit might inflate the cuff to levels
that can cause discomfort or harm to the patient. For
example, when the patient is:
• being transported over a very bumpy road
• moving the monitored arm
• a small child
When you turn the Auto Adjust feature off, the E Series
unit repeats the same cuff inflation pressure for every
measurement. Because this method does not readjust to
the patient’s previously measured blood pressure, do not
use fixed cuff inflation pressures unless you have
received the proper training.
To turn off Auto Adjust:
1. Press the Cuff Inflation softkey from the NIBP menu.
If the Cuff Inflation softkey is not displayed, see
“Displaying the NIBP Menu” on page 8.
The E Series unit displays the Cuff Inflation menu:
WARNING
Do not set cuff inflation pressure too high, particularly
for pediatric, or frail patients. Serious injury can
result.
