Operation
SatShare Operation
When the SatShare cable is connected to the Radical-7 Pulse CO-Oximeter and to a
multiparameter patient monitor, the Radical-7 Pulse CO-Oximeter automatically starts to operate
in the SatShare mode.
In the SatShare mode, Radical-7 Pulse CO-Oximeter operates as follows:
■ All visual alarms remain active.
■ All audible alarms may be disabled by software configuration of the Radical-7 Pulse
CO-Oximeter. Refer to Section 4, Alarms.
■ The SpO
2
and pulse rate numbers may or may not be displayed on the Radical-7 Pulse
CO-Oximeter display depending on the SatShare Numbers setting of the General menu.
Refer to Section 3, SatShare Setup.
■
All other items are displayed, including the alarm limits, the plethysmogram and Signal IQ waveform.
■ The user can access the menu system.
■ If the SatShare cable is connected to the Radical-7 Pulse CO-Oximeter only, and not to a
patient monitor, the SatShare cable type is flashing on the LCD screen.
■ Once the Radical-7 Pulse CO-Oximeter detects the presence of a patient monitor, the
SatShare cable type remains constantly displayed on the LCD screen.
■ Patient Alarms of the multiparameter patient monitor will be triggered by the alarm setting
of the patient monitor and not the Radical-7 Pulse CO-Oximeter. To synchronize the alarm
events set the alarm limits of the Radical-7 Pulse CO-Oximeter to those of the patient
monitor, or vice versa.
■ Once the Radical-7 Pulse CO-Oximeter detects that the SatShare cable is disconnected
from the patient monitor, or if the patient monitor is turned off, the Radical-7 automatically
returns to normal, standalone operation.
■ In the SatShare mode, the pulse beep tone of the Radical-7 Pulse CO-Oximeter is initially
set to the lowest volume (mute). The pulse beep volume can be manually increased. Refer
to Section 4, Traditional User Interface.
■
The Radical-7 Pulse CO-Oximeter may automatically set the averaging time during SatShare
operation. For averaging times of 10 seconds and higher, the Radical-7 Pulse CO-Oximeter
will automatically set the averaging time to 8 seconds during SatShare operation. Averaging
times of 2, 4 or 8 seconds remain unchanged during SatShare operation. When the Radical-7
Pulse CO-Oximeter returns to non-SatShare operation, the Radical-7 Pulse CO-Oximeter will
maintain the averaging time setting used in the SatShare mode.
■ When the Radical-7 Pulse CO-Oximeter starts to operate in the SatShare mode the
sensitivity mode is set to Normal sensitivity. The sensitivity mode can manually be set to
Maximum or APOD sensitivity. Refer to Section 2, Handheld Front Panel.
■ While operating in the SatShare mode, the Radical-7 Pulse CO-Oximeter may automatically
disable the SatShare interface if the perfusion index drops below 0.1% while the sensitivity
is set to Max sensitivity. To enable the SatShare interface again, set the Radical-7 Pulse
CO-Oximeter to the Normal or APOD sensitivity mode, increase the perfusion at the
measurement site (by warming the patient or sensor site), or move the sensor to a site with
better perfusion.
