NIBP is an abbreviation for automated non-invasive manometry, one of the data on the monitor that automatically detects and displays the patient’s systolic and diastolic blood pressure values at regular intervals. The NIBP is usually tied to the brachial artery of the arm with a restraint band and is often used during surgery or in intensive care units to facilitate the observation of patient vital signs and to avoid dangerous situations where blood pressure levels may change dramatically. The normal range is 90-140 mmHg for systolic blood pressure and 60-90 mmHg for diastolic blood pressure, and the patient should remain stable while the NIBP value is being measured; vigorous arm or body movement may affect the measurement and cause errors. Systolic or diastolic blood pressure above or below the normal range usually indicates that the patient has abnormal blood pressure and should provide timely feedback to the health care provider. If the blood pressure fluctuates significantly, medication can be applied as appropriate, such as oral medication as prescribed by the doctor or injectable medication added by the medical staff. However, it should be noted that the restraints should not be tied too tightly, and it is recommended that the restraints be loosened regularly to avoid affecting the patient’s blood circulation.
