(see also Labgrab FAQ) (see also Spreadsheets FAQ) Q1: how many variables will Rugloop capture ? At what sampling frequency ? A1: Rugloop will always capture ALL processed variables from the connected monitors to write them to file, for offline processing. The Rugloop screen, of course, cannot display all variables, and will provide you with a selection of them. The sampling frequency is monitor-dependent and ranges between 1 to 10 s, the average being 5 s. Q2: does Rugloop support realtime data capture? A2: Yes, as an option wave capturing is available in Rugloop. For more information click here . Q3: what PC is required to run Rugloop? A3: You need a PC capable of running Win2K, WinXP or VISTA, with as many serial ports as you want to connect devices. For Rugloop monitor-only, a PentiumII-class PC or better is sufficient. Count at least 10MB of free HD space, plus 2MB per hour of patient data you want to record. Q4: I cannot get connection to my monitor. How can I find out what COM port I need to select for a specific monitor? A4: Unfortunately, no uniform answer exists. Since this is dependent on your
specific PC environment, a procedure is required for proper setup. Luckily,
Rugloop remembers your settings, so you have to do this only once. - WHEN USING EXTERNAL SERIAL PORT DEVICES (like Demed 2-Port), YOU SHOULD TAKE CARE TO ALWAYS USE THE SAME USB CONNECTION ON YOUR PC. When changing the USB port, Windows will re-enumerate all the serial ports, requiring full reconfiguration of Rugloop. - at first, you need to know what COM ports are avialable on your PC. A useful tool to do so can be found here. - Once you have written down the available ports, this is the Rugloop configuration procedure:
Q5: The Rugloop log for the A2000 sometimes has a different name for the BIS data A5: The first lines of a typical Rugloop-generated .asp file looks as RGL checked files (...) LineType (...) ch1 BISBIT00 ch1 B34U04 ch1 DB11U03 ch1 DB12U01 2 (...) BISBITch1 BISch1 BISAch1 BISA2ch1 A2000Data 25ms Q6: What is the data format of Rugloop file data & how can I open RugloopII(c) and Labgrab data in a spreadsheet A6: RugloopII(c) and
Labgrab files are 'pipe'-separated ASCII
text files that can be read using any spreadsheet program. Just open Excel, and
find the file you want to open. Excel will recognise that the file is a
text file, and will present you with a 'text import wizard'. The complete
procedure is described in detail in the Labgrab manual, which can be downloaded here. Q7: Why do the Rugloop files' numbers look strange ? A7: Rugloop uses the scientific notation in the files. A typical Rugloop file line in this notation looks as
which corresponds to
in 'standard' notation. Scientific notation is expressed as mantissa"E"exp,
and is calculated as mantissa*pow(10,exp).
In the Format cells dialog, set the cells to 'Number' format.
Q8: I am connected to the monitor (Rugloop status is green) but no data is coming in A8: Most probably, Rugloop is receiving its own frames back. The internal
modem of many notebooks will mirror sent frames. Since these frames are properly
shaped, the Rugloop algorithm assumes a device is connected and is answering
properly (but without data). Solution: after the modem is disabled, Rugloop will no longer receive its own frames. To disable the monitor:
Q9: the captured video blocks randomly while recording A9: for some reason some audio encoders interfere with the video encoding. This effect is most apparent but not exclusively related to less powerful PC's. The best approach to avoid this effect (at the expense of larger data files) is to only apply video encoding while using raw audio capture. Notorious encoders are:
OK:
Q10: the Cardinal Health (Alaris) Asena randomly connects / disconnects. Th epump alarms with a 'Comms Timeout' A10: Two possible reasons may exist. The first is that the optical isolation in the pump does not work properly with a low battery when the pump is not externally powered. You should make sure to either use mains power or a fully charged battery for operation. The second reason is when using an Asena PK for a standard Rugloop-controlled TCI application: the Asena PK is not suited for remote control. Please use an Asena CC,GH, or TIVA for this purpose.
Q11: I am having general connectivity issues wihen using the Demed 4-port USB A11: this device is suspected to produce data errors in the following situations: * when used in areas / cases where electrocoagulation is applied: in this case, the observed error may even go as bad as an unexpected, sudden complete application halt * specifically, when used in combination with the Danmeter A-line monitor: here, an incompatibility is observed between the 2 devices. It shows as a regular 'framing error' warning in Rugloop. To eliminate the first as possible cause, please run a 'dry' case without a patient connected, out of the environment. If no errors occur, Please contact Demed for further information & support. For the second possible cause, please use a different serial port device, or contact Demed.
(see also Rugloop FAQ) (see also Spreadsheets FAQ) Q1: do I need Labgrab to process Rugloop-generated data ? A1: No, Rugloop output data is generated in ASCII text formats, and can be readily opened in Excel. BUT .... since Rugloop output data contains a lot of variables in a specific structure, Labgrab greatly simplifies processing Rugloop data for your presentations. Also, the Labgrab sampling wizard enables you to subsample Rugloop data over multiple cases automatically, a task which would take you hours otherwise.
(see also Rugloop FAQ) (see also Labgrab FAQ) Q1: the "Calculate K41" button does not seem to be active in the Schnider's PK spreadsheet A1: the "CalculateK41" button is calling a macro embedded in the file. Most probably, your Excel security level is set too stringent to execute the macro. (Excel: tools Menu -> Macro -> security: should be set to "medium", is now probably set to 'high') Q2: I can not get Cp and Ce after I fill the "time" and "infused vol" fields A2: Some general
