9.1.2 The Oscilometric method vs. the Korotkoff Sound Method
Blood pressure measurements by the oscillometric method and Korotkoff sound method have good correla-
tion with the invasive blood pressure measurement. Notwithstanding, any of the non-invasive blood pressure
measurements has its one-sidedness when it is compared to the invasive measurement. Studies show that,
the oscillometric method has its advantages over the Korotkoff sound method in less error, higher reliability
and stability especially in critical cases such as arrhythmia, vasoconstriction, hypertension, shock, etc.
9.2 Safety Information
 When taking the blood pressure measurement on a neonate patient. DO NOT operate in the Adult mode.
The high inflation pressure may cause lesion or even body putrescence. Even though the monitor can iden-
tify the cuff type so it will stop inflation and indicate “Cuff error” when taking the blood pressure measure-
ment for a neonate in the “Adult” patient type setting. The user (doctor or nurse) should pay more attention
to select the correct patient type.

It is recommended to take the blood pressure measurement manually

NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell disease,
otherwise, partial bleeding will appear.
 DO NOT wrap the cuff on limbs with transfusion tube or intubations or skin lesion area, otherwise, injury
may be caused to the limbs.

If the patient is moving or suffering tremble, hyperkinesia or arrhythmia, it may cause the inflation time of
inflatable balloon endures longer, which may not only prolong the measurement time, but also result in the
body wrapped by the cuff is troubled by purpura, hypoxemia and neuralgia because of the friction.

Before the measurement is carried out, select an appropriate measuring mode depending on the patient
type (adult, pediatric or neonate).

The air-hose which connects the cuff and monitor should be straightway without any tangle.
 When an adult patient is monitored, the device may fail in giving the blood pressure measurement if the
pediatric patient type is selected.

Prior to use of the cuff, empty the cuff until there is no residual air inside it to ensure accurate measurement.

DO NOT twist the air tube or put heavy things on it.
 When unplugging the air tube, hold the head of the connector and pull it out.

The NIBP measurement will not be affected when the monitor is connected to the patient on whom the
electro-surgical unit and defibrillator is being used.

The appearance of arrhythmia results in irregular heart beat which may affect the accuracy of NIBP meas-
urement. It is recommended to take the measurement again at this situation.

The blood pressure measurements determined with this device are equivalent to those obtained by a trained
observer using the cuff/stethoscope auscultatory method, within the limits prescribed by the American Na-
tional Standard, manual, electronic, or automated sphygmomanometers.
 The monitor can be used on the patients who are pregnant or pre-eclamptic, but close attention should be
paid to such patients.

The performance of NIBP function can be affected by the extremes of temperature, humidity and altitude,
please use it within the appropriate working environment.
9.3 Measurement Limitations
1. Serious angiospasm, vasoconstriction, or too weak pulse.
2. When extremely low or high heart rate or serious arrhythmia of the patient occurs. Especially auricular fibril-
lation will lead to unreliable or impossible measurement.
3. Do not take the measurement when the patient is connected with an artificial heart-lung machine.
4. Do not take the measurement when the patient uses diuresis or vasodilator.
5. When the patient is suffering from major hemorrhage, hypovolemic shock and other conditions with rapid
blood pressure change or when the patient has too low body temperature, the reading will not be reliable,
for reduced peripheral blood flow will lead to reduced arterial pulsation.
6. Patient with hyperadiposis.
9.4 Measurement Mode
There are three measuring mode for NIBP measurement:
•
Manual
: measurement on demand.
•
Auto
: continually repeated measurements at set intervals.
• STAT : continually rapid series of measurements over a five minute period, then return to the previous mode.
