b. Set Start Mode.
• Clock: after the first measurement, the monitor automatically
synchronizes NIBP automatic measurements with the real time clock.
• Interval: after the first measurement, the monitor automatically repeats
measurements at set interval.
c. Select the Main Menu quick key or to return to the main display.
Set A Non-Invasive Blood Pressure Measurement Interval
The N Series bedside monitor allows the clinician to set a pre-configured interval
for a NIBP measurement to be obtained automatically. To set an automatic
interval on the N Series bedside monitor:
a. Select the NIBP Measure quick key.
b. Select the desired interval.
Or
a. Select NIBP tile on the main screen to access the NIBP dialog.
b. Select Interval to select the desired interval from the dropdown list.
• Intervals include: 1 min, 2 min, 2.5 min, 3 min, 5 min, 10 min, 15 min,
20 min, 30 min, 1 h, 1.5 h, 2h, 3h, 4h, 8h: The monitor automatically
measures NIBP based on the specified time interval.
• Select Sequence to automatically measure NIBP based on the sequence
customized by the user in the Sequence tab.
c. Select the Main Menu quick key or to return to the main display.
Configure A Custom Sequence
To configure a custom sequence:
a. Select NIBP tile on the main screen to access the NIBP dialog.
b. Set Interval to Sequence.
c. Select Sequence tab.
d. Set Duration and Interval for each phase in the measurement cycle.
e. Select the Main Menu quick key or to return to the main display.
Factors that Affect Blood Pressure Measurement Accuracy
The accuracy of non-invasive blood pressure (BP) measurement has been shown

to be affected by numerous factors. Some of the more important aspects (based
on published literature) to consider while measuring BP are:
• The cuff should fit snugly, but with enough room for two fingers to be
placed between the cuff and the patient’s arm (on adults), and loosely on
neonates with little or no air present within the cuff.
• Use the Guidance Table provided to select the proper size cuff. Too small
a cuff has been shown to result in the overestimation of BP (systolic and
diastolic) while too large a cuff results in the underestimation of BP.
Ensure that the cuff is wrapped directly over the patient’s skin. BP measurement
could be 10 to 40 mmHg higher or lower than actual when the cuff is applied
over clothing.
• The cuff should be applied so that the center of the bladder in the cuff is
over the brachial artery. Use the reference marker for ver.
• For best results, the cuff should be placed on the arm at heart level and
the lower arm supported passively. Published data indicates that BP can
increase about 2 mmHg for every inch that the cuff is below heart level and
decrease by the same amount if above heart level.
• Avoid compression or restriction of the pressure hose. Do not place the NIBP
cuff on a limb that is being utilized for any other medical procedure, for
example, an I.V. catheter.
• Have the patient sit quietly for several minutes before BP measurement and
remain still during measurement to avoid unnecessary motion artifact. If the
patient has not rested before measurement, BP could be elevated by 10 to
20 mmHg.
• Do not talk to the patient during BP measurement as talking has been
shown to result in a 10 to 15 mmHg overestimation of BP.
• The patient’s back and feet should be properly supported with the legs
kept uncrossed. Unsupported back and feet could increase BP by up to 15
mmHg, while crossed legs could result in a 4 to 12 mmHg increase.
• Other factors that have been shown to result in an overestimation of BP are
labored breathing (5 to 8 mmHg), full bladder (10 to 15 mmHg), pain (10 to
30 mmHg).

INVASIVE BLOOD PRESSURES (OPTIONAL)
The N Series bedside monitor allows a clinician to monitor up to 8 invasive blood
pressures (IBP) simultaneously.
Adjust Invasive Blood Pressure Label
To adjust the label on an invasive blood pressure:
a. Insert IBP Module as needed.
