USING THE RECORDER

Starting a Recording Session
1. Insert a proprietary Welch Allyn SD card and a new AA battery.
2. After the battery door is closed, H12+ will power up and perform software and battery tests.
This takes a few seconds while the Hillrom splash screen is displayed. When finished, the
duration and sample rate are displayed.
3. Verify the set duration and sample rate.
a. If necessary, navigate to the CONFIGURE menu
to change the set duration and sample rate (see
Changing Duration and Changing Sample Rate).
4. Hookup the patient (see Patient Preparation).
5. Verify the quality of the hookup by checking the
impedances. Scroll through the main menu until
LEAD CHECK is displayed, press
Enter .
Note: Main menu options are displayed in the
middle of the screen with Up
‘▲’ and Down ‘▼’
indicators above and below the option to indicate
how to scroll to the next option. The current time
and date are displayed at the bottom of the LCD
screen.
Checking Impedances
LEAD CHECK is a valuable tool for verifying and optimizing signal quality after patient hookup and
before starting a recording.
From the main menu, scroll to LEAD CHECK, press
Enter .
A graph depicting the impedance measured at the
right arm (RA), left arm (LA), left leg (LL), and V1
through V6 electrodes is displayed from left to right in
vertical columns on the screen. The higher the solid
black oval indicator, the better the contact is between
the skin and the electrode.
An oval indicator positioned at the top the vertical
line means optimal high quality and good electrode
contact. For good-quality recordings, the bars
should reach or exceed the horizontal line on the
display. A low bar graph means poor electrode-to-
skin contact and high-electrode impedance. The
skin preparation should be repeated, and the
electrode(s) replaced.
Once acceptable impedance levels are verified, press
any of the three keys to return to the main menu.
6. Verify the amplitude and signal quality by displaying each of the leads. Scroll through the main menu
until DISPLAY ECG is displayed, press Enter .
