The MLS370/8 Blood Pressure Module Version 8 for Windows and MAC automatically detects, analyzes and reports a set of cardiovascular parameters from arterial or ventricular pressure signals, either online or offline. The Blood Pressure Module should be used with the latest version of LabChart.
The Classifier View allows for easy selection of pressure waveforms for further analyses. Pressure cycles that are contaminated by artifact, have abnormal cycle heights or cycle durations (frequency) can be excluded using the classifier. In addition, the classifier can be used to select pressure cycles that have increased frequency and/or amplitude for analysis. For example, increased heart rate in response to pharmacological agents is easily identified by a group of pressure cycles with decreased duration.


The Analysis View displays pressure cycles beat-by-beat or as the average of a specified number of cycles. Depending on the type of
signal under investigation (ventricular or arterial), commonly reported parameters specific to the type of signal (i.e. systolic pressure, EDP etc.) are labelled. These measurements are logged in the Table View for easy exporting.

The module also allows for these measurements to be displayed in LabChart as continuous data on separate channels. Raw data is unaltered by any calculations ensuring that the ventricular or arterial signals can be re-analyzed at any time.

Classifier View:

The Classifier View allows selection of cycles based on height and duration. The edges of the red boxes represent the cycle classification limits and can be dragged using the mouse to include or exclude detected cycles, in the analyses.

Detection & Analysis Settings:

The BP Settings dialog is used to set blood pressure detection parameters. The detection algorithm uses minimum cycle height and minimum cycle duration, with each detected cycle labelled. By selecting ventricular or arterial pressure, specific waveform parameters are calculated by the Module. Cycle averaging and isovolumic relaxation (Tau) options are also set in the window.

Analysis View:

Every beat, as well as the average of beats, is displayed in the Analysis View with vertical markers displayed for each ventricular or arterial cycle parameter. Scrolling horizontally will display each beat or average of beats in succession.

Table View:

All parameters calculated by the Module are recorded in the Table View. Table rows are linked to beats in the Analysis View so that highlighting a row will automatically show the corresponding beat(s) in the Analysis View as well as the original data in the LabChart View.

Available as Part of LabChart Pro:

The Blood Pressure Module is also available as part of LabChart Pro. Visit the LabChart Pro information page prior to making a purchasing decision. Existing LabChart users and PowerLab system purchasers can upgrade to LabChart Pro at a special price.
