NBP Monitoring
CAUTION – To obtain accurate blood pressure readings, keep the limb
and the cuff motionless.
CAUTION – The NBP cuff should be at the same level as the patient's
heart. If you cannot place the NBP cuff at this level, add to the measured
pressure values 1.4 mmHg for each 2 cm above the heart level, or
subtract 1.4 mmHg for each 2 cm below heart level.
CAUTION – NBP measurements may not be accurate if the patient is
convulsive, experiencing tremors, or is defibrillated during the
measurement.
CAUTION – NBP measurements may be affected by extremes of
temperature, humidity, and altitude. Always ensure that the Nightingale
PPM3 is operated and stored within its specified environmental conditions.
Note – Blood pressure measurements determined with this device are equivalent to those
obtained by a trained observer using the cuff/stethoscope auscultation method, within the
limits prescribed by the American National Standard, Electronic or automated
sphygmomanometers.
Note – The Auto Mode setting is remembered between power cycles. However, the
PPM3 does not start Auto Mode NBP measurements after power up until the NBP
Start/Stop key is pressed. This tells the PPM3 that the cuff has been applied to the
patient and that NBP monitoring should commence.
Note – NBP readings are not continuous, but are updated each time a NBP
measurement is taken. Use a shorter Auto Mode setting for more frequent updating of the
patient's blood pressure.
Note – During a measurement, a variety of safety checks are performed. These checks
can cause the measurement to be cancelled and pressure to be released from the cuff.
The safety checks include an overpressure check (to make sure the cuff pressure is not
greater than 270 mmHg), a check to make sure the measurement does not take longer
than 2¼ minutes, and other checks for technical problems such as a blocked line.
Note – This device functions according to specifications in the presence of common
arrhythmias such as atrial or ventricular premature beats or atrial fibrillation.
Note – This device can be used to determine blood pressure over a heart rate range of
30 bpm to 240 bpm.
