15.3 NIBP Measurement Limitations
• The effectiveness of the sphygmomanometer has not been established in pregnant, including pre-
eclamptic patients.
15.4 NIBP Display
• If NIBP measurement fails, “XX” is displayed; if NIBP measurement is not taken, “--” is displayed.
• Outlined NIBP numerics indicate that the measurement exceeds the NIBP timeout. So these NIBP
values are not recommended for reference. The setting of NIBP timeout can be changed in the
Configuration mode only. For more information, see 24.7.4.8NIBP Setup Tab.
15.5 Preparing for NIBP Measurements
15.5.1 Preparing the Patient for NIBP Measurements
• It is recommended that the patient calms down and relaxes as much as possible before performing
the measurement and that the patient do not talk during the measurement.
• It is recommended to have the patient sit quietly for several minutes before taking the
measurement.
• Other factors that have been shown to result in an overestimation of blood pressure are labored
breathing, full bladder, pain etc.
15.5.2 Placing the NIBP Cuff
• Using a cuff of wrong size, or a cuff with twisted bladder and kinked air tubing, can cause inaccurate
measurements.
• Do not touch or apply external pressure against the cuff and air tubing during NIBP measurement.
This may cause inaccurate blood pressure values.
• Use care when placing the cuff on an extremity used for monitoring other patient parameters.
15.6 Changing NIBP Settings
• For known hypertensive patients, you need to set initial cuff pressure to a higher value to reduce the
measurement time.
