16 Non-invasive blood pressure

Overview

The non-invasive blood pressure (NIBP) measurement uses the oscillometric measuring
principle. The cuff is inflated with a pressure slightly higher than the presumed systolic
pressure, then slowly deflated at a speed based on the patient's heart rate, collecting data
from the oscillations produced by the pulsating artery. Based on this data, the unit calculates
values for systolic, mean and diastolic pressures.
Blood pressure measurements determined with this device are equivalent to those obtained by
an intra-arterial blood pressure measurement device. Multiple intra-arterial sites were used.
You can set the NIBP module into an automatic cycling mode to make measurements at
desired time intervals. You can also measure NIBP continuously for five minutes in STAT mode
or take separate single measurements.
NOTE: Intervals below 10 minutes and STAT measurements are not recommended for
extended periods of time.
WARNING The NIBP measurement is indicated for patients weighing over 5 kg (11 lb).

Module description

NOTE: In the monitoring system, use only one module at a time for measuring NIBP.
