Trend Setup and Use
INTRODUCTION
The Rad-57 can store 72 hours of SpO
2,
Pulse Rate, SpCO*, SpMet* and Perfusion Index
trend data, captured at 2 second intervals. This trend data can then be transferred to a
PC for evaluation.
Trend data is stored in non-volatile memory, so it is not erased when the device is shut off
or when the batteries are replaced.
A Pronto serial cable is required to connect the sensor connector of the Rad-57 to the
PC and TrendCom software is required to download the trend data on to the PC. Refer
to Section 10 - Accessories and contact Masimo to acquire these optional items. 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.
*See Model Summary for applicable device.
TRENDCOM UTILITY INSTALLATION
Copy the TrendCom utility from the CD onto a PC running MS-Windows.
TRENDCOM UTILITY OPERATION
