Estimate Cardiac Output from Arterial Blood Pressure (ABP): this automated routine requires a continuous noninvasive blood pressure waveform—such as the signal from the NIBP100D module—and uses the Liljestrand and Zander estimator to calculate stroke volume and cardiac output on a cycle-by-cycle basis. Output results to speadsheet, journal, and waveform. This is a new feature available for AcqKnowledge 4.4 and above.
Focus Areas is a powerful analysis tool available in AcqKnowledge 4.3 or above. Focus Areas allow the user to specify and mark areas of interest in the data for further analysis. Next, automated analysis routines or the cycle detector can be run specifically on the Focus Areas instead of the entire data file. This in-depth tutorial covers the basics of Focus Areas as well as specific examples for Automated BP Analysis (2:12), Automated EDA Analysis/ GSR analysis (5:52), Automated Ensemble Averaging (9:39), and Automated Find Cycle Analysis (13:20). AcqKnowledge Data Acquisition & Analysis Software
This screencast shows how to use the Focus Areas > Define Between Events utility that is accessible from the Analysis menu in AcqKnowledge 4.3 or above. This automated utility is a simplified alternative to using Find Cycle tools to create Focus Areas. The example demonstrates how to create Focus Areas from digital inputs.

Introduction to the AcqKnowledge Gastric Wave Analysis and Gastric Wave Coupling routines. These routines use autoregressive time frequency analysis to determine the classification of gastric waves present in an EGG file. The waves are divided into three primary categories – normal, bradygastric and tachygastric and the percentage for each category is determined. The coupling analysis determines the degree of coupling between two channels of EGG data and can be used to determine the degree of slow-wave propagation across the stomach.

AcqKnowledge 4.3 implements a new routine that locates and marks animal ECG complex boundaries. This routine functions the same way as the Locate Human ECG Complex Boundaries routine contained in previous AcqKnowledge versions but it optimized for the faster heart rates of small animals. Simply enter in the average heart rate for the file and run the routine to locate and mark ECG complex boundaries. AcqKnowledge Data Acquisition & Analysis Software
