PATIENT SETUP
Admit Patient And Enter Demographics (Manual Entry)
The Patient Management dialog allows the clinician to admit a patient and enter
patient demographics. Admitting also restores default (preconfigured) settings
and clears the previous patient’s information.
After a patient is manually discharged, the monitor automatically admit a new
patient. To manually admit a patient on the N1 monitor:
a. The monitor prompts to admit a new patient in the following situations:
• After being switched off for the selected time period*, the monitor
automatically discharge the previous patient and admit a new patient at
startup.
• If the monitor has not detected certain patient vital signs (ECG, SpO2, PR,
RR, NIBP) for 30 minutes, the clinician will be prompted to admit a new
patient once continuous monitoring is detected.
*Time period configurable.

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

10
BeneVision N1 Quick Reference Guide
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).
