1 Product overview
1.1 Introduction
This document provides information for maintenance and service of the Patient Data Module
v2, hereafter referred to as PDM v2.
NOTE: Some information in this document may vary compared to older PDM v1 Module version.
If needed refer to earlier document version(s) for more information about older PDM v1 Module
version.
NOTE: If you are not using the PDM with the CARESCAPE Monitor B850, refer to the Patient Data
Module (PDM) Service Manual.
The PDM is a data acquisition device for a GE modular system. It provides a connection from
the patient monitor to the patient, processes the patient data signals and stores a limited
amount of patient data (24 hours captured at 1 minute resolution) for seamless transport.
The PDM contains software and hardware to monitor the following parameters:
•
ECG/respiration
•
Noninvasive blood pressure
•
Pulse oximetry
•
Up to four channels of invasive blood pressure
•
Cardiac output or two temperature channels
•
Defibrillator sync/analog out interface
1.2 Measurement principle
The PDM is a portable acquisition device. It collects data from a patient, converts the data to a
digital form for processing, and sends the data to a bedside, transport or surgical monitor for
further processing and display.
The data that it collects, converts, and sends includes the patient’s vital signs and physiological
waveforms. It also stores patient history including trends and special events, and setup
information such as blood pressure zero points and alarm limit settings. The patient history is
stored so that the collected information is transferred with the PDM when a patient is
transferred to a different monitor.
