Propaq M Overview

This chapter includes step-by-step procedures for the following types of maintena nc e tests:

• Calibration and Calibration Checks

• NIBP Valve, Pump, and Tubing Integrity Tests

• Operational Tests

• Functional Verification Tests

At a minimum, a trained biomedical technician must perform a CO
calibration check once per year. A CO

The Troubleshooting chapter in this manual may recommend performing one of more of the
NIBP valve, pump, and tubing integrity tests to help identify and correct potential issues with
the NIBP valve, pump, and/or tubing.

It is necessary to perform Functional Verification Tests after a module is repaired to en sure that
the functions of the Propaq M unit work properly.

Because the Propaq M units must be maintained ready for immediate use, it is important for
users to conduct the Operator’s Shift Checklist procedure at the beginning of every shift. This
procedure can be completed in a few minutes and requires no additional test equipment. (See
the ZOLL Propaq M Operator’s Guide for the Operator’s Shift Checklist.) It is highly
recommended that the Operational Tests be performed at regular intervals to augment the
automatic testing the Propaq M does to ensure readiness.

Overview

This chapter contains functional descriptions of the components contained in the Propaq M and
the Propaq M options.

Circuit Distribution

The Propaq M unit consists of one key PCB assembly, the Monitor Board, as well as a few
modules and assemblies: the Front Panel Keypad assembly, Status LCD Board, Dock
Connector Board, and Display. The NIBP, CO2, and SpO2 circuitry reside on modules that
connect to the Monitor Board.

Chapter 6

Functional Description

Monitor Board

The Monitor board integrates the analog circuitry and interface circu itry for patient parameters,
a digital processing section as well as user interface controls, audio control, and power circuitry
for the entire system and charging circuitry for the battery. The Propaq M system relies on a
centralized dual processor engine for its computing needs. The Main Processor (MP) serves as
the primary user interface engine and provides connectivity needs, while the Patient Processor
(PP) controls the patient monitoring function. An additional power controller micro-controller
(PC) controls the power sequencing, and battery/charger interface.

9650-0804-01 Rev. A ZOLL Propaq M Service Manual 63

CHAPTER 6FUNCTIONAL DESCRIPTION

Main Processor (MP)

The MP section controls the user interface, connectivity needs, as well as data logging,
printing, and general system control. It consists of the CPU, program memory Flash and
SDRAM, Communication with modules/circuits: USB Client, USB Host, Debug Ports
(JT AG,Serial), Storage memory for 24 hour disclosure data, Internal VGA display and interface
circuit, LED indicators, Key Pad, and Audio circuit. The MP also controls the real-time clock
and interface to the power controller processor, battery and charger.

Patient Processor (PP)

The Patient processor circuitry supports the data acquisition, signal processing and
conditioning, analysis and control algorithms required for the physiological senso rs. It consists
of the processor, program memory Flash and SDRAM as well as interface circuitry to
physiological sensor modules/circuit s .

Power Controller (PC)

The Power Controller (PC) micro-controller controls the power sequencing to turn the dev ic e
on and off when the power switch is pressed. It also communicates to the battery charger and
battery via a serial SPI bus. Additionally, the PC controls the Status LCD and communicates
battery and charger status to the MP.

ECG 3/5 or 12 Lead Circuitry

Propaq M supports 3/5 lead and 12 lead ECG acquisition. Analog circuitry provides signal
conditioned data through an A/D converter to the PP. All of the signal processing, lead
derivation, fault detection is performed by the PP. The ECG circuitry utilizes a CPLD for
control of analog circuitry and transmission of data to the PP across an isolation barrier. A
common connector is used to receive 3/5 Lead ECG cables with a 12 Lead ECG extension. The
ECG signals from the external connector on the left side panel are connected to the monitor
board through a flex cable to J28.

Impedance Respiration

Propaq M provides the circuitry for impedance respiration measurements in 3/5 and 12 lead
configurations. This circuitry provides a low-current 72kHz AC signal across leads I and II of
the ECG cable. The signal is passed through a synchronous demodulat or and decoded by the PP
through the ECG CPLD.

Blood Pressure NIBP

The Propaq M NIBP circuitry resided on module that connects to the Monitor board through
J32. The PP communicates to the NIBP module via a bi-directional, serial bus. The NIBP
module supports both dual lumen and single lumen cuffs. The NIBP pump and valve hoses are
connected to the cuff con nector on t he left side pa nel and to th e filter on the rear e nclosure. The
pump and valve are connected to the NIBP module by short, 2-wire cables.

Invasive Blood Pressure (IBP)

Propaq M supports up to 3 IBP measurement channels. The IBP circuitry supports AAMI
BP-22 transducers (5uV/V/mmHg). The PP communicates directly to the IBP ADC over an
isolated serial bus through the FPGA. The IBP probes connect to the monitor board through
the IBP/Temp wire harness which connects to J33 of the Monitor board.

End tidal CO2 (CO2)

Propaq M supports an Oridion Microstream® CO2 module. The CO2 module mounts to the
Monitor board and communicates to the board through a cable connected to J50. Serial

communications from the monitor board is implemented via a UART on the PP. The CO
module obtains gas samples from the sampling lines through tubing and a 3-wire cable

connected to the left side panel.

Thermometry

Propaq M supports two simultaneous temperature measurements. YSI400/YSI700 series
probes are used to make temperature measurements. Data is communicated to the PP from the
Temperature ADC via and isolated SPI bus through the FPGA. The Temperature probes
connect to the monitor board through the IBP/Temp wire harness which connects to J33 of the
Monitor board.

Power Circuitry, Battery Charger, DC-DC converters

Power circuitry for all subsystems reside on the Monitor Board. Auxiliary Power and Battery
Power are automatically switched to provide constant current, the unit draws current from
auxiliary power when present. There is a smart battery charging circuit that will charge the
battery when Auxiliary power is present. Switching mode DC-DC converters are utilized to
make internal 6V, 5V, 3.3V, 1.8V and processor core voltages. Regulators are used to provide
regulated supply voltages with low dropout for low current consumption circuits. Each of the
isolated modules, Temp/IBP, ECG, SpO2 have independent power supplies. Isolated power
supplies are designed for isolating Patient Applied Parts. The MP via the FPGA GPIO has the
ability to shut down voltage rails or power to individual patient parameters. Power from the
battery connects to the Monitor board through J29. Auxiliary powe r connects to the Monitor
board through J31.

USB Host Port

Propaq M Monitor Board incorporates one USB Host ver 1.1 port. The port uses the USB
controller built into the PXA270 Main processor. Full speed of 12 Mbps and Low speed

1.5Mbps are supported. The Host port supports a U S B flash memory stic k for d ata ex po rt . The
USB host connector is in the right side panel and connects to the Monitor board through J44.

Lithium Ion Battery

The portable Propaq M device is powered by a removable Lithium Ion bat tery pack. This
battery pack incorporates protection circuitry and "smart battery" circuitry. The battery power
is routed from the 2-pin connector on the rear of the device to J29 of the Monitor board. The
