Preparing to Take Measurements
9650-0914-01 Rev. C R Series Non-Invasive Blood Pressure (NIBP) 15
Auto Adjust
The R 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 R 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 R 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 12.
The R Series unit displays the Cuff Inflation menu:
2. Press the Next softkey until Auto Adjust is highlighted.
3. Press the Inc softkey until Auto Adjust is set to OFF:
4. Press the Return softkey to return to NIBP menu.
The R Series unit repeats the selected cuff inflation pressure for every measurement.
