Datex-Ohmeda S/5 Collect

Selecting the displayed waveforms

The waveform selection list on the left (Waveforms) defines the waveforms that are available for viewing in the boxes. The list contains all the waves the maximum monitor configuration can measure.

•To select only one wave, click the wave in the list, and to select more waves, hold down Shift and click the desired waves.

•To deselect waves in the list, hold down Shift and click the wave.

•After selecting the wave(s), click the arrow button next to the waveform selection box and select the wave you wish to see in the waveform box.

NOTE: When using the 12-lead ECG module, only ECG1, ECG2 and ECG3 are available.

Changing the waveform sampling interval

Click Freq and select the frequency. The sampling frequency in the online mode can be selected from 300 to 1 Hz.

During network communication the maximum number of waves that can be requested is 24.

During serial communication, the maximum frequency available depends on which waveforms are being collected. For example, ECG has 300 Hz, hemodynamic waveforms 100 Hz and gas and spirometry waveforms 25 Hz.

4–6

Using S/5 Collect online

If too many waves are selected, a prompt to reduce the amount of waveforms is displayed. The limit is a total of 600 samples per second; for example

2 * 300 Hz or

1 * 300 Hz + 3 * 100 Hz or

6 * 100 Hz or

2 * 100 Hz + 6 * 25 Hz or

8 * 25 Hz.

If you are collecting data from a longer period of time to an ASCII file, select a low frequency to reduce the file size.

NOTE: With certain monitor software versions, there may be a risk that the waveform transfer is interrupted after selecting the 1 sec as the trend sampling interval. In such case, you will also be prompted to select less waveforms.

Data file size

The table on page B-6 in "Appendix B" shows the frequency for each wave. The value must be multiplied by 2 to get the number of bytes/second. The overhead each second is 40 bytes. Trend data takes about 1500 bytes per request.

An example of asking parameters each hour for a total period of 2 days (all trend parameters are saved in the .drc file regardless of your selection):

(2 x 24) x 1500= 72 kB.

An example of collecting 2 waveforms per hour and trend data each 5 seconds:

3600 seconds	2 x InvBP waves +	trend each 5 seconds =
3600 x	2 x (100 x 2 + 40) +	3600/5x1500 =
864 kB + 144 kB= 1008 kB

It is not possible to predict the exact file size of the ASCII files. The number of characters in the values may make a big difference in the file size, for example, if the invasive pressure is 3.00 mmHg or 120.00 mmHg there are 4 or 6 characters written in the file.

The online data collecting shows the file sizes while saving the data and the data rate in kB/min. From these values, you can estimate the hard disk occupation and when the saving can be made.

NOTE: The frequency selection does not affect the data transfer rate, which is always the maximum. The data is stored in .drc files for each wave at its individual rate. The data is displayed and saved in ASCII files at the chosen frequency.

4–7

Datex-Ohmeda S/5 Collect

Changing the period of waveform display

Click Period and select 5 sec, 10 sec, 30 sec, 1 min., 5 min.

When you change the period of the waveform display, the start and end times on the scroll bar at the bottom of the page change accordingly. By moving the scroll box you can move to the desired part of the waveform.

The recommended value depends on the selected waveform. For example, if you select 1 minute for ECG waveforms, the artifacts cannot be read from the displayed waveforms. When you change the period, for example, to 10 seconds, the waveform becomes much clearer.

Auto-selection of displayed trends

Clicking Auto Select will select and display all data with a positive value greater than 1 times the resolution as defined by the divider for the parameters in the configuration window.

Checking the latest numerical parameter value

The latest read numerical parameter value is shown to the right of the trend box under the trend selection box in a digit field. The latest read values are also displayed next to the parameters in the Parameters list.

4–10

Using S/5 Collect online

Changing the trend sampling interval

Click Interval and select 1 sec, 5 sec, 10 sec, 30 sec, 1 min, 5 min, 10 min, 30 min or 1 hour.

NOTE: 1 sec and 5 sec are not available during network connection.

When you want to see quick changes in the trends, select a short interval, for example, 5 seconds. When you want to see the overall direction of the trends, select a longer interval, for example, 1 minute. If you are collecting data from a long period of time, for example several hours, and have selected a short interval, the .drc file becomes quite large.

NOTE: With certain monitor software versions, there may be a risk that after selecting the 1 sec trend interval, the waveform transfer is interrupted. In such case, you will be prompted to select less waveforms.

Changing the trend scale

Click Scale and select the desired trend time scale from values 1 min, 5 min, 10 min, 20 min, 30 min, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours,

24 hours and Auto. The trend boxes start showing trends using the selected scale. The start and end times under the trend panel change accordingly.

If you select Auto, the time scale is autoscaling all the time: the start time is the start of the collection period, or the moment the graph was cleared last, and the end time is the time of the last package received.
