BIOPAC NIBP100D Noninvasive Blood Pressure Monitoring System

Overview

The BIOPAC NIBP100D Noninvasive Blood Pressure Monitoring System is designed for measuring blood pressure in subjects ranging from small children (approximately 4-5 years) to large adults.

Key Features

• Accurate noninvasive blood pressure values
• Comfortable for subjects to wear
• Real-time, continuous, noninvasive blood pressure
• Easy to use

System Description

The NIBP100D system provides a continuous, beat-to-beat blood pressure signal recorded from the fingers. It outputs a waveform similar to a direct arterial pressure waveform and displays systolic, diastolic, mean blood pressure, and heart rate.

It utilizes a double finger cuff, comfortable and easy to place, available in three sizes to accommodate various age groups and sizes. The system interfaces with BIOPAC MP160/150 or MP36/36R/35/45 Data Acquisition Systems via specific interface connectors and cables. The AcqKnowledge or BSL PRO software visualizes the blood pressure signal and provides detailed beat-to-beat analysis.

The NIBP100D is calibrated using a standard blood pressure cuff on the upper arm. The unit automatically takes a measurement for calibration. During recording, it alternates between fingers to relieve pressure, with user-selectable intervals up to 60 minutes. Calibration readings are taken periodically to ensure accuracy.

Setup and calibration take less than three minutes. The system employs a vascular unloading technique, a refined version of the Penáz principle, for continuous noninvasive blood pressure measurement using concentrically interlocking control loops.

Hyperbaric/Hypobaric Chamber Setup Guidelines

• Cuff controller and CNAP monitor must be in the same chamber with identical pressure environments, as both have pressure sensors for surrounding pressure.
• Pressure changes should be continuous, not abrupt.
• For hypobaric environments, take measures against device overheating (e.g., dim CNAP display, do not restrict airflow).
• Ensure no draught on the cuff.
• Maintain the hand at heart level in a steady position.
