This document describes the features, functions, operation of the Wireless System for DPT®
transceiver system for use with Hospira Transpac IV® and Hospira Transpac IT® disposable
pressure transducers.
The base system includes a transmitter module and a minimum of 2 receiver channels to support
the wireless transmission of 2 invasive blood pressure signals. Additional receiver modules can be
purchased to support up to 5 transducers per system.
This manual is intended for use by trained medical clinicians familiar with multi-parameter patient
monitors.
INDICATIONS FOR USE
Wireless System for DPT® is indicated for use when invasive blood pressure monitoring is needed
and a cable-free connection is desired between Transpac IT® or Transpac IV® transducers and a
patient monitor. Wireless System for DPT® supports only pressure transducers provided by
Hospira.
CONTRAINDICATIONS
The use of Wireless System for DPT® is contraindicated:
•
Do not use to synchronize external devices.
•
Do not use during MRI or PET scanning.
•
Do not use to trigger aortic balloon assist devices.

BATTERY LEDS
The battery indicator has 3 LEDs to indicate battery charge (full, medium, low). See [insert cross
reference to go to the Battery LED table in chapter on Troubleshooting]
When not connected to AC, the system powers-off after 60 minutes if the battery discharges to a
predefined safe low voltage.
When the transmitter is connected to AC, the LEDs flash to indicate that the battery is charging.
ALARM LED
The Alarm LED flashes to indicate and alarm state.
See [insert cross reference to go to the Alarm LED table in chapter on Troubleshooting]
POWER ON/OFF
The transmitter is switched ON or OFF by pressing the power button.
OK
The OK button is used during the wireless linking process.. A Wireless System for DPT equipped
monitor will display a triangular “linking” waveform prior to the formation of a wireless link to a
Wireless System for DPT transmitter. Press the OK button to immediately confirm the link.
The OK button is also used during ZERO ALL. When a calibration signal is displayed, press the OK
button to zero all channels. See Zeroing on page 13 for more
information.
NEXT
The NEXT button cancels a wireless linking process if pressed while the “linking” signal is displayed
on a monitor. The wireless linking process is then initiated with the next available monitor.
If the NEXT button is pressed while the transmitter is already linked, the link is broken and a
wireless linking process is initiated with the next available monitor.
BATTERY
The Li-ion battery is accessed via the back panel. A built-in battery charger automatically charges
the battery whenever the transmitter is connected to AC power.
Battery replacement should only be done by a trained technician.
Contact Hospira customer support for replacement batteries.

Receiver Modules
Wireless System for DPT receiver modules are connected to the IBP sockets of a patient monitor
and present the same electrical load and response as industry standard 5 µV/V pressure
transducers. They are powered by the monitor and contain no batteries or other serviceable parts.
The illustration shows the modules with GE Solar
customer service to order adapters for monitors from other manufacturers.

RECEIVER MODULE 1(REQUIRED)
Receiver module number 1 is required. It simulates the presence of the transducer connected to
transmitter socket “P1” and is color coded red.
RECEIVER MODULE 2 (REQUIRED)
Receiver module number 2 is required. It simulates the presence of the transducer connected to
transmitter socket “P2” and is color coded blue.
RECEIVER MODULES 3, 4, & 5 (OPTIONAL)
Receiver modules for channels 3, 4, and 5 are optional. The channel number is selected by the
switch shown below.
RECEIVER CABLES (REQUIRED)
The receiver cables distribute power and data between the modules.
MONITOR ADAPTERS (REQUIRED)
The receiver modules require plug adapters that are often unique to each monitor manufacturer.
Contact Hospira customer service for a list of compatible monitors and to order adapters.

System Overview
The Wireless Transducer is designed to eliminate the wires and cables that tether patients to
monitoring equipment. The cable function is replaced by the Wireless Transducer.
The Wireless Transducer can be powered by a battery for portable use, but is intended to be
operated using standard AC power when available. While connected to AC power, the Wireless
Transducer also functions as a battery charger.
CALIBRATION BUTTONS
Five buttons provide calibration information. The Transpac Transducer sends a 100 mmhg
calibration signal on the selected channel for 10 seconds. The receiver and monitor use this
calibration signal for a secondary monitor and channel number confirmation. The calibration
buttons zero the channel if pressed while the calibration signal is

The Transpac Transducer is turned on by activating the power button.
TRANSPAC TRANSDUCER PIGTAIL SOCKETS
The Transpac Transducer Pigtail Sockets are color coded for jumper cable attachment. Inserting
the plug into the socket triggers a power on cycle.

BATTERY LED
The Battery LED indicates that the power is on.
When not connected to AC, the LED flashes and the system powers off after 60 minutes if the
battery discharges to a predefined safe low voltage.
ALARM LED
When the Transpac Transducer is connected to AC, the LED flashes to indicate that the Transpac
Transducer is charging.
The Alarm LED flashes when the alarm sounds. It blinks when wireless interference is
detected.
OK
Press the Ok button to immediately confirm and link. The monitor displays a corresponding “linking”
waveform on the monitor.
If you press the Ok button when a calibration signal is displayed, the output of all channels are set to
zero. See Zeroing on page 13 for more
information.
NEXT
The Next Button selects the next receiver if it is pressed when the “linking” signal is displayed. The
“linking” signal is redirected to the next receiver. The Next Button triggers new link.
If the Next Button is pressed when it is already linked, the link is broken, and “linking” signal is
displayed on the next available
monitor.
