Rad-5/5v Signal Extraction Pulse Oximeter Operator’s Manual 4-15

Trend Setup and Use (Rad-5 only)

INTRODUCTION

The Rad-5 can store 72 hours of SpO

and Pulse Rate and Perfusion Index trend data,

captured at 2 second intervals. This trend data can then be transferred to a PC for evalu-

ation.

Trend data is stored in non-volatile memory, so it is not erased when the unit is shut off or

when the batteries are replaced.

A special serial cable (see Section 10,

Accessories

) is required to connect the sensor con-

nector of the Rad-5 to the PC. Patient monitoring is not possible while trend memory is

being transferred to a PC.

A trend data download is initiated using the TrendCom utility which downloads the trend

data and saves it to a space-delimited ASCII text (.out) file.

TRENDCOM UTILITY INSTALLATION

Copy the TrendCom utility from the CD onto a PC running MS-Windows.

TRENDCOM UTILITY OPERATION

1. Disconnect patient sensor and/or cable from the Rad-5.

2. Connect the mini-D end of the PRONTO serial cable to the Rad-5 patient cable

connector (see Section 2,

Rad-5 front panel controls

) and connect the DB-9 end to

a COM port on the PC.

3. Turn the Rad-5 on

4. Start the TrendCom Utility

5. Select the appropriate COM port number, if necessary.

6. Push the RETRIEVE TREND button on the TrendCom utility.

Select the desired location and assign a filename for the trend file. Press Save.

7. The Rad-5 will display “dat out” while trend data is being transferred.

A progress bar will advance to indicate the status of the download.

Larger trend files will take longer to download. Transfer time is approximately 20

seconds per hour of trend data.

Note: During download of trend information, all normal Rad-5 functions are unavail-

able and the keypad is locked, except for the power button.

8. When trend data transfer is complete, close TrendCom and disconnect the Rad-5

from the PRONTO serial cable.

9. Turn the Rad-5 off to exit the trend download mode.

Note: USB to serial port adapters are not supported for trend transfer.

Note: Enabling trend (setting Trend to “ON”) will erase all trend information in the Rad-5.

ERASING TREND MEMORY

To erase (clear) the trend memory, turn the trend off and back on again. Enabling trend

(setting Trend to “ON”) will erase all trend data.

Note: Turning trend off will not erase trend memory. You may turn trending off and still

retrieve the trend data using TrendCom.

Turning the Rad-5 off or replacing the batteies will not erase the trend data.

Turn trending off before storing the unit for any length of time.

TREND DATA FORMAT

After a successful download of the trend data, a .out file will be created containing the

trend-dump information in ASCII delimited format. The format is defined in the following

table.

Exception

Messages

The exceptions are displayed as a 3 digit, ASCII encoded, hexadecimal

value. The binary bits of the hexadecimal value are encoded as follows:

000 = Normal operation; no exceptions

001 = No Sensor

002 = Defective Sensor

004 = Low Perfusion

008 = Pulse Search

010 = Interference

020 = Sensor Off

040 = Ambient Light

080 = Unrecognized Sensor

100 = reserved

200 = reserved

400 = Low Signal IQ

800 = Masimo SET. This flag means the algorithm is running is full SET

mode. It requires a SET sensor and needs to acquire some clean

data for this flag to be set
