Determine the best location to attach the patch and optional lead wire onto the patient, but do not attach at this time
Prepare the patient’s skin. If the patient has hair in any of the patch site, shave it with a safety razor. Use an alcohol pad and rub the sites briskly until the skin reddens. Let the skin air dry before proceeding.
You do not need a Bluetooth USB Adapter to use the DR400, however, a Sena Parani Bluetooth USB Adapter for Serial Port is required to view live ECG using the PCPatch utility. Contact your distributor to find out more about this feature.
When the data on the DR400 is erased using the PCPatch utility, the date and time on the recorder will be updated to match the date and time on the PC. After erasing, you can view the date/time on the right-hand side of the PCPatch Settings screen.
Using a USB power source, it should only take about 10 minutes to recharge the recorder after a 24 hour study. The battery will take at most, 2 hours to fully recharge if fully depleted. The light will be a solid orange when the battery is fully charged.
If the DR400 is used frequently, for example, not left in the charger for more than a day or two, it is fine to keep it plugged in between uses. If you use your DR400 less frequently, for example it might be left in the charger for more than a few days, it is best to remove the DR400 from the charger once full charged. You will then want to plug it in again to ensure it is fully charged before your next study, but that should only take a few minutes.
I just hooked up a patient and pressed the Event button to start the DR400. How do I know if the DR400 is currently recording?
First, to start recording, you must hold the EVENT button down for 3 seconds, until the green light goes off. If you did this, and you then saw the green light flash for about 30 seconds, this indicates that the DR400 started a new recording.
If you are still concerned, you can confirm that you are recording by recording an event. To record an event, quickly press the EVENT button and the recorder will flash green for about 10 seconds. If the recorder did not flash green or responded in a different way, refer to the second page of the Quick Start Guide “TO START RECORDING” to determine what is happening.
We expect the electrodes to last for about 3 or 4 days, but of course this may vary for each patient. Patients can and should wear the electrodes while taking a light shower, but swimming and bathing are not recommended as this will shorten the life of the electrodes and possibly damage the recorder.
The PCPatch utility can be used to upload the recorder data to either the HE/LX Analysis or LX Remote software. By using the PCPatch to upload the data, you are still able to use the analysis software for other patients while the file is being uploaded. Once uploaded, you can open the patient record in the Holter software to update patient information and start analysis.
