Wave Sectors 2-4
Wave Sectors 2 through 4 are automatically populated when parameter sources (cables/tubing) are
connected to the HeartStart MRx. If the parameter source is the configured choice of a particular wave
sector, it is displayed in that wave sector. If you connect a parameter source that is not configured to be
displayed, it is displayed in the first empty wave sector. If you subsequently connect the configured
parameter source, it replaces the current parameter. For invasive pressures, you should label your
waveforms as they are connected to avoid possible confusion.
Changing Displayed Waveforms
Wave Sector 1 has a dedicated Lead Select button to change the displayed lead/source. Waveforms
displayed in other wave sectors may be changed for the current patient through the menu. See
“Menus” on page 19.
Parameter Blocks
Measurements for monitored parameters are provided in the parameter blocks. Parameter Block 1
always contains the heart rate and HR alarm settings. The position of the other parameters are in fixed
locations depending upon the options which were included in your HeartStart MRx. Each
measurement is labeled and displays the current value and the high and low alarm limit settings or the
(alarms off) icon. A “-?-” is displayed until a valid measurement can be obtained.
Your parameter text colors will always match their corresponding wave.
Parameter Alarm Messages are displayed in the space above each numeric value, replacing the
parameter label, except HR.
Turning Parameters On/Off
SpO2, Invasive Pressures, EtCO2 and Temperature parameters are activated when the associated
parameter cable/tubing is connected. To turn the parameter off, disconnect the cable/tubing from the
HeartStart MRx. A prompt message (see Figure 8) alerts you that the parameter has been disconnected
and requests confirmation to turn the parameter off.
Figure 8 Parameter Message
Turn off SpO2?
Yes
No
Press the Menu Select
button to select Yes, confirm your action and turn off the parameter. If you
do not wish to turn the parameter off, use the Navigation Buttons to highlight No. Press the Menu
Select button to keep the parameter on and reconnect the cable/tubing. You can also ignore the
message and reconnect the cable/tubing. The HeartStart MRx will detect the connection and remove
the message.
Soft Key Labels
The four soft key labels correspond to the soft key buttons located immediately below. These labels
change, as appropriate, according to the current display view and function. Soft key labels appearing as
gray text indicate that the soft key is inactive.
