Introduction

The M3000A Multi-Measurement Server, the M301 A and M3016A Measurement Server Extensions and the M3046A Compact Portable Patient Monitor form a flexible, portable, battery or line powered patient monitor.

The M3000A Multi-Measurement Server acquires the physiological signals ECG, respiration, invasive and non-invasive blood pressure, oxygen saturation of the blood, and temperature. These signals are converted into digital data, and processed before being communicated to the Monitor.

The M301 A/M3016A Measurement Server Extensions acquire the physiological signals invasive blood pressure, CO2 respiratory gas measurement, and temperature. These signals are converted into digital data, and processed before being communicated to the Monitor.

The M3046A Compact Portable Patient Monitor receives the processed data from the Measurement Server, and, if present, the Measurement Server Extension, examines it for alarm conditions and displays it. The Monitor also provides operating controls for the user, and interfaces to other devices.

The M3080A #C32 12V adapter allows use of a vehicle power supply for the instrument and the M3080A #C30 battery charger allows the recharging of batteries for the instrument.

In this Book

This Service Guide contains technical details on the Monitor, Measurement Server and Measurement Server Extensions.

The purpose of this book is to provide a technical foundation for the monitoring system in order to support effective troubleshooting and repair. The book is not intended to be a comprehensive, in-depth explanation of the product architecture or technical implementation. Rather, it is developed to offer enough information on the functions and operations of the monitoring systems so that engineers who repair them are better able to understand how they work.

It covers the physiological measurements that the products are designed to provide, the Measurement Server that acquires those measurements, and the monitoring system that displays them.

Introducing the Instrument Components

The M3000A and M3000A #D06 Multi-Measurement Servers, the M3015A and M3016A Multi-Measurement Server Extensions and the M3046A Compact Portable Patient Monitor

form a flexible, portable, battery, or line-powered patient Monitor. (Note: The combined devices are referred to as the ,QVWUXPHQW in this manual.)

The M3000A Multi-Measurement Server acquires the physiological signals ECG, respiration, invasive and non-invasive blood pressure, oxygen saturation of the blood, and temperature. The M3000A #D06 Multi-Measurement Server acquires the physiological signals ECG, respiration, non-invasive blood pressure, and oxygen saturation of the blood. The signals are

converted into digital data, and processed before being communicated to the Monitor. (Note: The server device is referred to as the Measurement Server or simply the 6HUYHU in this

manual. As well, unless specified, documentation intended for the M3000A Server is also intended for the M3000A #D06 Server.)

The M3015A Measurement Server Extension acquires the physiological signals invasive blood pressure, temperature and partial pressure of carbon dioxide (via sidestream sampling). The M3016A Measurement Server Extension acquires the physiological signals invasive blood pressure, temperature and partial pressure of carbon dioxide (via mainstream sampling).

When using the M3015A and M3016A, all the signals are converted into digital data, and

processed before being communicated to the Monitor. (Note: Server extension devices are referred to as the Measurement Server Extensions or simply ([WHQVLRQV in this manual.)

The M3046A Compact Portable Patient Monitor receives the processed data from the Measurement Server and the Measurement Server Extension, examines it for alarm conditions, and displays it. The Monitor also provides operating controls for the user, and interfaces to other devices. (Note: This monitoring device is referred to as the Monitor in this manual.)

Section 1 - Monitor Description

The M3046A Patient Monitor is a small size, lightweight monitor with a TouchBar human interface. The monitor has a color display with a wide viewing angle, and excellent visibility from a distance, so that data can easily be recognized. For applications where a larger display is required, an additional display can be connected to the monitor via the standard VGA output.

Trend data, and manual and automatic event storage, together with a range of report styles are available for tracking and documenting the patient’s progress.

The Monitor receives the processed data from the Measurement Server and the Measurement Server Extension, examines it for alarm conditions, and displays it. The Monitor also provides operating controls for the user, and interfaces to other devices.

1-10 Introduction to the Instrument

M3000A/M3046A/M3015A/M3016A Service Guide

Monitor Theory of Operation

The Monitor receives data passed from the patient through the Measurement Server and, where present, the Measurement Server Extension. The Monitor displays the data in numerics and waves on the screen.

The Monitor is prepared with a number of software modules, which communicate with each other as shown in the diagram below. The Monitor software communicates with the Measurement Server and, where present, the Measurement Server Extension via a normal local area network (LAN) link. Data from the Monitor can be output to a printer via an infrared serial link or via the LAN connector to a central print server. The Monitor can communicate with an Agilent Information Center via the LAN Connector (wired network) or via the Wireless LAN Assembly (wireless network) when the appropriate options are present.

'LVSOD\ DQG 8VHU ,QWHUIDFH 6RIWZDUH 0RGXOH

The Display and User Interface Software displays measurement data and status information on the color LCD display, and processes the operator inputs from the HIF Controller. The interface consists of the following sub-modules:

•Screen Configuration.

•Numerics and Wave Presentation.

•Key and TouchStrip Processing.

•Alarm and Status Presentation.

$ODUP 0DQDJHU 6RIWZDUH 0RGXOH

The visual and audible alarms generated by the Measurement Server, the Measurement Server Extension or by the Monitor software modules are assigned priorities by the Alarm Manager. The Alarm Manager also:

•Monitors the “alarm suspended”, “alarm silence” and “alarm reminder” functionality.

•Manages alarm latching (alarms remain in effect until reset or turned off by the user).

•Triggers the Nurse Call Relay.

•Generates alarm event triggers for any user-defined trigger conditions.

$GPLW 'LVFKDUJH 7UDQVIHU $'7 6RIWZDUH 0RGXOH

This module maintains the patient’s demographics and controls the upload of trend data from the Measurement Server and the Measurement Server Extension. It allows the user to:

•Admit a new patient.

•Transfer a patient to another Monitor.

•Discharge a patient.

7UHQG 6RIWZDUH 0RGXOH

This module manages a trend database. It stores physiological values from the Measurement Server and from the Measurement Server Extension in two separate databases, a short-term and a long-term database. The contents of these databases is battery-buffered, so that no data is lost in the event of a power failure.

(YHQWV 6RIWZDUH 0RGXOH

The events software module allows the user to take snapshots of the Monitor state and store them for later viewing or printing.This can be done automatically, triggered by alarms, if the monitor is configured appropriately. The types of data that can be captured are as follows:

•All physiological values.

•All current alarms.

•The last 20 seconds of wave data.

3ULQWHU 0DQDJHU

The printer manager formats and prints the following reports on either a locally attached printer or a remote printer connected to the Instrument via the M3 Print Server:

•7DEXODU 7UHQG 5HSRUW—The printer manager takes raw data from the trend module and generates a formatted report. The user can specify whether to print short-term or long-term trend data, and the period for which the data should be printed.

•(YHQW 5HSRUW—The printer manager takes raw data from the event module and generates a formatted event report. The user can specify a manual event, an alarm event, or a print screen report.

•(YHQW /LVW 5HSRUW—The printer manager takes the raw event list data from the events module and generates a formatted event list report.

See Chapter 2, Installing the Instrument for more details on connecting to a printer.

A number of drawing functions support the printer manager and provide it with graphics capabilities. The output from the printer manager is in PCL (Printer Command Language) format, and is fed to the locally attached printer, which is connected via an infrared data link, or to a remote printer. If the link to the printer is interrupted for a certain time, the printer manager displays a prompt of the color LCD display, notifying the user.

,U'$ 0DQDJHU

The IrDA manager is responsible for sending raw data to the local printer in a format that complies with the IrDA (Infrared Data Association) standard. The IrDA manager provides a general printer device interface to the printer manager, and maps the general printer services to the IrDA protocol. The general printer services are as follows:

•Establishing and terminating the printer connection.

•Transferring data to the printer.

•Retrieving the printer status.

The IrDA manager feeds the printer status (time out, paper out, and so on) back to the printer manager, which in turn notifies the user of any errors in the print process.

&RPPXQLFDWLRQ 6RIWZDUH 0RGXOH
