Other parameters are defined/established by the PortiLab™ system

2.1.11 SON™ Format - CED Cambridge Electronic Design™ (*.SMR)

A multichannel data file describing the ECG and BP signals (and, optionally, also other signals) created by the CED™ Cambridge Electronic Design™ acquisition system.

The channel containing the ECG and BP signal can be selected by the operator. If necessary, the operator may invert the ECG trace, modify the ECG zero line offset and the rescale factor for the ECG and BP signal.

Other parameters are defined/established by the CED ™ system

2.1.12 SIGMA Medizin-Technik VAGUS™ Format (*.CVA)

A multichannel data file describing the ECG and BP signals (and, optionally, also other signals) created by the SIGMA Medizin-Technik GmbH VAGUS™ acquisition system.

The channel containing the ECG and BP signal can be selected by the operator. If necessary, the operator may invert the ECG trace, modify the ECG zero line offset and the rescale factor for the ECG and BP signal.

Other parameters are defined/established by the VAGUS ™ system.

2.1.13 Text format (*.TXT or any other extension, e.g. *.ABT)

Text files with a freely modifiable extension provide compatibility e.g. with Axon™ text files format (*.ABT). 

 

2.2 The following RRI and BP (SBP, MBP and DBP) files can be used:

2.2.1 BRH Format (*.BRH)

The input file for analysis (extension BRH) is a text (ASCII) file, a five-column table. The columns from left to right and delimited by Space are as follows: Running Time in ms, RRI's in ms, Systolic Blood Pressure (SBP) in mmHg, Mean BP (MBP) in mmHg, Diastolic BP (DBP) in mmHg. 
E.g.:
3320 932 122.30 93.60 79.24
4238 918 120.74 92.47 78.33
5154 916 119.57 91.25 77.08
6036 882 118.74 90.87 76.94
…. …. …. …. …. …

2.2.2 BMEYE™ Nexfin™ CSV files (*.CSV)      

                                             
The Nevrokard BPV and BRS Analysis software can analyze CSV files recorded with the Nexfin™ hemodynamic diagnostics and short-term monitor (BMEYE, Amsterdam, The Netherlands). This is a multichannel system capable of monitoring a number of hemodynamic parameters.

E.g.:

time(ms),"IBI(s)","HR(bpm)","SYS(mmHg)","DIA(mmHg)","MAP(mmHg)","LVET(s)"...
21425,"0,795","75,25","141,75","84","103"...

22220,"0,775","77,25","145","89,5","107,25"...
....

2.2.3 Finometer™ Format -Beatscope™ Files

A multichannel data file created by the Finometer™ or Portapres™ with the Beatscope™ software from the Finapres Medical Systems™.

2.2.4 MS-Excel files (*.CSV)

Nevrokard BPV and BRS are compatible with all multi-column Microsoft™ Excel files, regardless of the number of columns. The locations of signals ECG (RRI, HR or Running Time), SBP, MDP and DBP in the available channels, gain and offset can be freely selected.

2.2.3. PowerLab™ Chart text files

The software can analyze data files recorded with the PowerLab™ acquisition system and exported as text files (extension TXT) from the Chart™ software designed by  ADInstruments™.  

2.2.5 Text format (file extension can be modified).

Multichannel text files using any delimiter (tab, comma, space, semicolon) and any extension (which can be freely modified) are compatible. The locations of signals ECG (RRI, HR or Running Time), SBP, MDP and DBP in the available channels, gain and offset can be freely selected. This feature provides compatibility also with the Finometer™ and old MS-DOS Finapres™ recordings.

 

3. Nevrokard CVP Analysis The following data formats can be used: 3.1 Finometer™ Format - Beatscope™ Files  (file extension can be modified) A multichannel data file created by the Finometer™ with the Beatscope™ software from the Finapres Medical Systems™ (http://www.finapres.com/).   3.2 Niccomo™ TXT Format Files (*.TXT)   A multichannel data file created by the Niccomo™ non invasive continuous cardiac output monitor manufactured by Medis Medizinische Messtechnik™ (http://www.niccomo.com/).

 

The following data formats can be used:

4.1 Binary Format (*.BIN)

This file may be either an independent recording or one of the channels in multiple channel recordings, to be separated off-line by the Nevrokard HPMA File Preparation module.

Type: Small Integer
Range: -2048..+2048 (!!)
Format: signed 16 bit

4.2 Laser Doppler Format (LDDA v.5.0 and more), (*.LDF);

4.3 LDDA v. 4.0 Compatible Format (*.LDD);

4.4 LDDR Compatible Format (*.LDR)

These formats are compatible with older versions of the Nevrokard LDDA software.

4.5 Moor™ Compatible Files (*.TXT)

These up to four-channel  data files are recorded by the Moor Instruments™ laser Doppler blood perfusion monitor. The channel of the LD signal can be selected by the operator. Other parameters are defined/established by the Moor™ system.

4.6 PeriSoft™ Format (*.TXT)

These files are compatible with ver. 5.0 of the PeriSoft™ software.

4.7 Text Format (*.PRN)

This is a two-column text (ASCII) file. The first column is running time in ms, the second column is Laser Doppler data in PU. The columns are delimited by Space.

E.g.:

1000140
