Chapter 1 Maintenance Tests Propaq MD Overview This chapter includes step-by-step procedures for the following types of maintenance 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 CO2 calibration and an NIBP calibration check once per year. A CO2 calibration check may be performed at any time to verify the CO2 calibration.
CHAPTER 1 MAINTENANCE TESTS This chapter describes the following maintenance tests: Calibration and Calibration Checks • NIBP Calibration Check • CO2 Calibration Procedure • CO2 Calibration Check NIBP Valve, Pump, and Tubing Integrity Tests • Leak Test • Deflation Test • Inflation Test Operational Tests • Physical Inspection of the Unit • Keypad Test • LED Test • LCD Test • RFU Indicator Test • Audio Test • Printer Test • Battery Test • Fan Test • NIBP Test Functional Verification Tests • Leads Test • Hear
Calibration and Calibration Checks Calibration and Calibration Checks NIBP Calibration Check Equipment Single lumen BP hose, a 500 cc volume, and a calibrated manometer or pressure gauge (< = 1mmHg accuracy). If a 500 cc volume is not available, an Adult BP cuff wrapped around a rigid cylinder (such as a glass jar) will suffice. Note: This test is to be performed for the following target pressures: 50 +/- 5 mmHg, 150 +/- 5 mmHg, and 250 +/- 5 mmHg. Procedure 1. Power on the Propaq MD. 2.
CHAPTER 1 MAINTENANCE TESTS Acceptable Results The unit passes the test if Pd-Primary is less than or equal to 3.0 mmHg and Pd-Safety is less than or equal to 4.0 mmHg for all three target pressures. Corrective Action If readings fail to meet the required accuracy, the NIBP module requires replacement or factory analysis and realignment. 8 9650-0801-01 Rev.

The SpO2 module communicates across an isolation barrier using a UART on the PP. Signals from the probe are routed to the SpO2 module through a flex cable that connects to J41 of the Monitor board.
CHAPTER 6 FUNCTIONAL DESCRIPTION module contains power supplies, charging and discharge circuitry, pacing circuitry, and the Pads/Paddles ECG preamplifier and impedance circuitry. Communication with the Defibrillator/Pacer module is a function of the PP. The ECG-Charger board contains the charger circuit, ECG acquisition circuitry, and protection components. The Processor-Bridge-Pacer board contains the micro controller, CPLD, Pacer, and defibrillation shock delivery circuit.
Overview Printer Propaq MD uses an internal thermal printer of 50 mm paper size that is built into the Defib section of the enclosure. Communications with the printer is bi-directional, serial, (Main CPU to/from printer) and complies with the software/hardware interface of the internal printer. Communications are implemented using hardware Universal Asynchronous Receiver. Transmitter (UART). The printer is controlled by the MP and is connected through a cable to J46 and J49 of the Monitor board.
