Noninvasive Blood Pressure Measurement

NIBP Data Recording and Analysis from BIOPAC

The NIBP100D noninvasive blood pressure system provides a continuous, beat-to-beat, blood pressure signal recorded from the fingers of a subject.

   

finger cuff BP sensorsThe noninvasive blood pressure (NIBP) monitoring system uses a double finger cuff that is comfortable for the subject to wear and easy to place on the hand. Includes three cuff sizes to accommodate small children through large adults. The system is very user-friendly and the initial setup and calibration period takes less than three minutes—that time includes placing the cuff around the upper arm and the sensor on the fingers. Placing the finger sensor is as simple as sliding the subject’s fingers through the two cuffs.

The system outputs a continuous blood pressure waveform that is similar to a direct arterial pressure waveform. The monitor displays values for systolic, diastolic, mean blood pressure, and heart rate.

The NIBP100D interfaces with an MP150 data acquisition system or third-party data acquisition system via a DA100C and TCI105 Interface Connector. AcqKnowledge software displays the blood pressure signal, plus systolic, diastolic, mean blood pressure and heart rate, and will also provide a detailed beat-to-beat analysis of the blood pressure signal.

Continuous and noninvasive blood pressure control

The NIBP100D is calibrated using a standard blood pressure cuff that is placed around the subject’s upper arm. The unit automatically takes a blood pressure measurement from the subject and uses the value for calibration purposes. During the calibration process the system locates the pulse at the finger and performs a partial occlusion. It will switch from one finger to the next during the course of the recording to relieve the pressure from the occluded finger. The interval between finger rotations is user-selectable and can be as long as 60 minutes. During the rotation, the system takes another calibration reading to ensure that values are accurate.

The system employs a vascular unloading technique to measure blood pressure at the fingers. A refined version of the Penáz’ principle is used to deliver a continuous noninvasive blood pressure signal. The method is based on concentrically interlocking control loops for accurate long-term readings of finger blood pressure.

The NIBP100D can be used in hyperbaric and hypobaric chambers (see specifications for setup guidelines).
