C. Tips for Using the IQmark VSM IrDA Interface

If your computer is equipped with an IrDA sensor, you can capture vital signs

measurements simply by pointing the IrDA sensor at the front panel of the IQmark VSM

and displaying the Control Panel. This topic presents some tips and suggestions on the

best practices for using the IrDA interface of the IQmark VSM.

MDG provides the IrDA interface as an easy way to obtain a snapshot of the vital signs

measurements into a patient's medical record. MDG does not intend that the IrDA link be

used as an alternative to a USB or serial port connection to the IQmark VSM for

extended monitoring periods. The software does not allow the user to initiate a new NIBP

measurement from the Control Panel (the Start button is disabled). The reason for this is

that the IrDA is a wireless data link and is not as inherently reliable as the USB or serial

port connections.

MDG recommends the following workflow when using the IrDA link to communicate

with the IQmark VSM.

1. First use the IQmark VSM to acquire the desired vital signs measurements.

2. When you are satisfied with the measurements displayed on the front panel of the

IQmark VSM, align the IrDA sensor of your computer with the front panel of the

IQmark VSM.

3. The maximum range of the IrDA link is approximately 3 feet (one meter) so be

sure that you are holding the computer close enough to the IQmark VSM.

4. Display the IQmark VSM Control Panel by clicking on the New Vital Signs

button.

5. The measurements will appear on the displays of the Control Panel dialog box.

6. Click on the OK button of the Control Panel dialog box. The software will

disconnect from the IQmark VSM and the measurements will be added to the

patient's medical record.

Notes:

1. When you display the Control Panel, the Status indication in the lower portion of

the dialog box will indicate "IrDA --Connecting...". It normally requires around

five or six seconds to establish a link. However, it occasionally requires as long as

10 seconds to establish a connection.

2. When the IQmark VSM detects a valid communications link with the PC it will

sound a tone sequence indicating a successful connection. The tone pattern is a

low frequency tone followed by a high frequency tone. The Status indication will

show "IrDA -- Connected".
