Blood Pressure Analysis

AcqKnowledge Stellar BP Data

AcqKnowledge extracts various cycle-by-cycle measures from arterial blood pressure (ABP) and ECG signals. Use an NIBP100D Noninvasive Blood Pressure system, or other, continuous blood pressure amplifier to record blood pressure, or use a catheter to record direct arterial blood pressure. The software can measure Systolic BP (SBP or PSys), Diastolic BP (DBP or PDias), Mean BP (MAP or Pmean), Heart Rate (BPM), Peak to Peak Blood Pressure (PPBP), and dP/dt max and min on a cycle-by-cycle basis for real-time display of the data.

The software also includes a fully automated analysis routine that scores the waveform and exports all of the results to a text file or to a spreadsheet.

  • If the ECG and blood pressure signals have not been classified when this analysis is performed, events for diastolic, systolic, and ECG boundaries will be inserted as necessary.
  • If systolic, diastolic, and Q events are already present on the signals, however, they will be used.

On a cycle-by-cycle basis, the arterial blood pressure analysis transformation extracts the following measures:

Ejection timeET
Heart rateHR
Maximum dP/dtdP/dt max
Mean blood pressureMBP
Minimum dP/dtdP/dt min
QA IntervalQA

When textual output is used, the average of all of these measures will be output as the last row of the table.
