User's Manual

The 3160 MRI Physiological Monitoring System includes the following Vital Sign
Parameters:
1.1.3
User Interface. A simple to use interface has been developed to minimize operator learning
time. On the Display Control Unit (DCU), there is a Rotary Knob (which detents from selection to
selection) that is used to access the parameter menu's, access the various setup features and finalize any
changes to the setup of the monitor. Frequently used menus (such as: Alarms, Trends and Recorder)
have a Control Key which, when pressed, will open the associated menu. On the Wireless Processor
Unit (WPU), the operator needs an external display and a keyboard to access the various features.
1.1.4 Versatility. With its diverse offering of vital sign parameters, the 3160 MRI Physiological
Monitoring System may be configured to meet the monitoring needs of a wide spectrum of patients
from Neonate to Adults. Every available parameter may be easily accessed and adjusted to the unique
needs, condition and situation of each patient.
1.2 Wireless Processor Unit (WPU). The WPU contains wireless transceivers, data acquisition
and processing circuitry that communicate with the wireless Display Control Unit (DCU), ECG
(WECG) module and SpO2 (WSpO2) module.
1.2.1 Operating Environment. The WPU is designed to operate at the 5,000 Gauss line in the
generated RF field of an MRI system measured from the center line of the bore.
1.2.2 Power Supply. The WPU Power Supply is designed to operate on the floor at least 10 feet
from a 1.5 Tesla unshielded MRI system (200 Gauss). When attached, the power supply charges the
WPU battery pack whether the WPU is operating or not.
1.2.3 Battery Operation. The WPU will operate at least eight (8) hours with EtCO2 and all optional
devices running with NIBP performing automatic readings at five (5) minute intervals.

1.3 Patient Connections. The physical patient connections for NIBP and the Anesthetic Agents
options are located on the Patient Connection Unit (PCU, See Figure 1-1). ECG, SpO2 and
Respiration all use wireless technology to deliver their measurements to the Wireless Processor Unit
(WPU).
1.3.1
NIBP and Agent Monitoring. The PCU contains the physical connections for the Non-
Invasive Blood Pressure (NIBP) and, when installed, the optional Anesthetic Agents parameters. If
Anesthetic Agents is installed, the PCU also contains a water trap to prevent moisture contamination of
the agent components.
a. Operating Environment. The PCU is designed to operate at the 5,000 Gauss line in
the generated RF field of an MRI system measured from the center line of the bore.
