reusable or repairable, the Hewlett-Packard Sales Office will provide information about proper
packaging materials and methods.
1.1.6 Functional Description
The Hewlett-Packard HP M1403A Digital UHF Telemetry System consists of a pocket-sized
transmitter with removable lead set, a modular receiver, and a mainframe that accommodates
up to eight receiver channels.
System Functions.
The HP M1403A provides ECG information, alarms, inoperative indications
(INOPs) and status information for up to eight patients. Installed on a Serial Distribution
Network (SDN), the HP M1403A functions like eight individual bedside monitors with patient
data appearing either at an HP Central Monitor or at
an
HP 78508A Patient Information Center
(PIC). A receiver mainframe with eight receiver modules is equivalent to eight patient bedside
stations, and a maximum of 24 patient bedsides may reside on one SDN system. Displays,
control functions (such as gain), recordings and alarms are controlled from the central station.
Recordings also may be initiated from
the
transmitter. Extended system functions such as
bedside overview, remote arrhythmia monitoring, remote data management, and remote
clinical data access is provided by some central stations.
Operation.
Using UHF radio waves, the transmitter sends two digitized ECG signals to a
receiver module in the associated mainframe. These signals (ECG 1 and ECG 2) can either be
passed on directly for display over the SDN, or can be used to derive other cardiac vectors
(reconstructed leads).
The transmitter supports a three-electrode set for single lead operation, and a four- or
five-electrode set for dual-lead operation. Both ECG leads have pace-pulse detection in the
transmitter, which improves detection of pacemaker signals. Each channel
has
user-selectable
bandwidth and gain setting to optimize display and Cardiotach monitoring, and minimize false
alarms.
General l-3
When the system is monitoring two leads at the same time, either of these signals may be
displayed and used for heart rate. When the four-wire cable is used with standard electrode
placement, any two of the following leads can be selected for display or used for heart rate:
Leads I, II, III, aVF, aVR or aVL.

can
be powered by any standard nine-volt battery, subject to the
life-expectancy limits listed in ‘Pdble l-3, Specifications, for different types of batteries.
The transmitters’ button may be configured at installation to transmit a nurse-call request
and/or generate a strip recording, or may be permanently disabled. The button functions
can be disabled by the user with the button on-off key at the central station on a per-patient
basis. Because no other controls are patient-accessible, the transmitter cannot be turned off
inadvertently.
To eliminate the potential confusion of displaying incorrect patient data due to crosstalk or
malfunction, each transmitter transmits a unique identity (ID) code. The transmitter button is
used during installation to set up the transmitter ID code with a companion receiver.
The diference between the HP M1400A and HP M1400B is in output power only. The HP
M1400A transmits at 2 milliwatts; the HP M1400B transmits at 4 milliwatts.
Receiver Mainframe.
The HP M1401A Receiver Mainframe contains up to eight HP M1402A
Receiver Modules, each of which is frequency-matched to the corresponding transmitter.
The mainframe provides indicators to identify hardware and software failures. It calculates the
heart rate from ECG A for each receiver module, and transmits the result with the ECG wave
information and any alarms, INOPs, and status information over the SDN.
In the event of an electrode INOP condition in multi-lead configurations, the receiver
mainframe can be configured for fallback mode so it will switch automatically from the
inoperative lead (normally ECG A) to a secondary lead (normally ECG B), if available. Under
extended monitoring, with the four-electrode lead set, if both the ECG A and ECG B leads are
inoperative, the Cardiotach will switch to another lead, if available.
The mainframe also initiates a recording and/or nurse call alarm at the central station if the
transmitter button is pressed. These functions are enabled or disabled during configuration.
A BNC connector on the mainframe is used to connect with the antenna system output. The
BNC connector is connected to a network that distributes the combined RF signal to each
receiver module.
The Patient
Monitor/Halter Recorder Interface option (hereafter referred to as the Analog Output option)
increases the capability of the HP M1403A by providing
an
analog version of ECG waveforms
to bedside monitors and Holter recorders. The option also provides synthesized pace pulse
waveforms, and a Leads Off INOP when leads-off, battery-dead, invalid data and system
malfunctions are detected.
ST Segment Analysis and Two-Channel Delayed Recording Option.
The ST Segment
Analysis provides the capability to calculate ST segment depression or elevation simultaneously
on two channels of ECG. The two measurements are updated every 15 seconds and are
continuously displayed. In addition, the user can enable and disable individual ST channels,
and is notified of INOP due to artifact.
l-4 General
With the Two-Channel Delayed Recording option, the user can initiate two-channel manual
or automatic delayed recordings through a PIC-manually by pressing the nurse call button,
or automatically by patient alarm. The recorder strip contains data beginning 10 seconds
prior to the initiation and ending 5 seconds after the initiation, for a total run time of 15
seconds. Delayed recordings may be preempted by recordings of a higher priority and saved as
superseded data. Delayed recordings can be cancelled entirely by pressing the STOP button on
the
recorder faceplate.
Antenna System.
The Dynamic UHF Antenna System minimizes signal-to-noise degradation by
using high-performance, active antenna/combiners with integrated amplifiers to ensure uniform
performance throughout the covered area.

Note
frequencies listed for each country have been approved, or are
pending approval. However, transmitter HP M1400B-with 4 milliwatt outputis authorized for use in the USA only, regardless of frequency.
Channels legal in the United States of America, including service channels,
are listed in ‘Ihble l-l. Channels 11 through 28 are used for U.S. Government
institutions (Veterans Administration, US Army, US Navy, US Public Health
Service, and others). These institutions do not require an FCC license, but
U.S. Government use of these channels outside of the range of 11-28 requires
Federal Communications Commission (FCC) approval.
