  • Page 32 Performance Verification Performance Verification This section gives instructions for running Performance Verification tests on the M3500B/M5500B. The tests are sequenced to check more basic functions first, and then build on that to check more complex functions. We recommend you perform these tests in this sequence. If desired, you can make copies of the Test Results Matrix (page 2-3) and use it to record results.
  • Page 33 Performance Verification Functional Checks The following functional checks exercise the basic functions of the defibrilla- tor/monitor. They are intended as a broad check of the unit’s performance, and are designed to complement (not replace) the Diagnostic Tests described later. If all elements of a test pass, record that test as a PASS and return to the main diagnostic menu by pressing .
  • Page 34 Performance Verification Shock Advisory Functional Check This section describes how to check the Shock Advisory function. 1. Connect the ECG simulator to the pads cable. Set the simulator for nor- mal sinus rhythm (NSR), 1mV amplitude, at some nominal rate (e.g., 60 bpm).
  • Page 35 Performance Verification Functional Check This check only needs to be performed if SpO is installed. 1. Attach the SpO transducer to your finger. 2. Activate Manual Mode and press the SpO softkey to turn SpO 3. The SpO value displayed should be in the range of 95-100%. If the value is less than 95%, check that your finger is fully inserted into the sensor and properly positioned.
  • Page 36 Diagnostic Tests Diagnostic Tests The M3500B/M5500B includes an extensive set of diagnostic tests, which test the major hardware components of the defibrillator. The System Log These instructions describe how to print the system log, which includes the unit’s serial number, hardware configuration, and a listing of error codes. The System Log should be printed each time a Performance Verification Test is run.
  • Page 37 Diagnostic Tests Extended Self Test The Extended Self Test checks that all internal processors are operating and communicating with each other. The instructions below describe how to run the Extended Self Test. If all results are as described, the unit passes this test.

Return to the main Diag- nostic Test menu by pressing . If there is any failure, begin trouble- MAIN shooting and repairing the unit as needed.
  • Page 50 Diagnostic Tests Safety Tests This section covers tests of the defibrillator’s electrical safety. These safety tests only need to be performed if the customer normally uses the defibrillator with the AC Power Module connected. If the defibrillator is nor- mally used on battery power only, these tests do not need to be performed. Using the procedures called out by the manufacturer of the analyzer in use, measure and record the following data.

  • Page 179 Theory of Operation Overview This chapter describes the internal operation of the M3500B/M5500B. This description is at the functional-block level. The information is presented in two ways: PCA Descriptions For each Printed Circuit Assembly (PCA), a description of the major functions performed on that PCA. System Functional Descriptions For each major system function, a description of how the signal is routed through the various PCAs.
  • Page 180 PCA Descriptions PCA Descriptions The sections following provide descriptions of the functions handled by each PCA. Control PCA The Control PCA performs the following functions: System level processing. System level control and clock functions, including: Control of power up and power down sequences. Storage of configuration selections made by the user.
  • Page 181 PCA Descriptions Interface PCA The Interface PCA performs the following functions: Interconnection site for: ECG leads cable and SpO module. All front panel keys. All front panel LEDs (Manual, Sync, Pacer). Ambient light sensor and IRDA interface. ECG analog front end for ECG from 3/5-lead cables. Detecting and initial processing of front panel key presses, except for keys OFF, 1, 2, 3 which only pass through the Interface PCA and are detected and processed on the Control PCA.

  • Page 185 System Functional Descriptions ECG Monitoring Functions There are two separate ECG front ends - one for signals coming in on the pads cable, and one for signals coming in on the 3- or 5-lead ECG cable. ECG - Pads The ECG signal picked up by the disposable defibrillation pads is carried by the pads cable to the pads connector, and then to the Power PCA.
  • Page 186 System Functional Descriptions Patient impedance functions The M3500B/M5500B measures patient impedance in 2 ways: an impedance measurement before the shock, and a resistance measurement during the shock. Before the Shock The M3500B/M5500B makes a small-signal AC impedance measurement (at 32 kHz) in the steady state situation before a shock is delivered. This mea- surement (called PCI) is used to determine whether the pads are connected to the patient, or not.
  • Page 187 System Functional Descriptions Defibrillation Functions The following sections describe the defibrillation functions. Charging There are 2 events that can initiate a charging cycle: In AED Mode, when the analysis algorithm determines a shock is needed and sends a signal to another section of the Control PCA. In Manual Mode, when front panel key #2 (CHARGE) is pressed, the keypress is transferred from the key to the Interface PCA via a flex circuit.
  • Page 188 System Functional Descriptions At any time during delivery of the shock, it detects an open circuit (voltage too high for that point in the waveform) or a short circuit (current too high for that point in the waveform). Should any of these conditions be detected, the Power PCA terminates deliv- ery of the waveform and disarms the capacitor.
  • Page 189 System Functional Descriptions Pacing Functions Pacing is initiated and controlled by pressing front panel keys. These key presses are transferred from the keys to the Interface PCA via a flex circuit. The key presses are detected and processed by the Interface PCA and then passed to the Control PCA via a large ribbon cable.
  • Page 190 System Functional Descriptions Audio Functions The M3500B/M5500B has 2 types of audio output: tones, and voice prompts. Both are generated and controlled by the Control PCA, which also amplifies the signals and passes them directly to the speaker via a dedicated connector and wire pair.
  • Page 191 System Functional Descriptions Indicator Functions All panel LEDs (Manual, Sync, Pacer) are controlled by the Control PCA. The LEDs are connected into the Interface PCA via flex circuits; they are then routed to the Control PCA via a ribbon cable. M3500B/M5500B Service Manual 6-13...
  • Page 192 System Functional Descriptions Key Functions All front panel keys connect to the Interface PCA via flex circuits. Main Keys The key presses from the 4 main keys (OFF, 1, 2, 3) pass through the Interface PCA and then on to the Control PCA via a large ribbon cable. The Control PCA then interacts with the other parts of the system as needed to respond to the keypress.
  • Page 193 System Functional Descriptions Printing Functions All printing data are handled by the Control PCA. Waveforms, graphics, numeric values, and messages are all generated and formatted by the Control PCA, using either data it has or data it receives from other parts of the unit. This data is then passed to the Printer via the printer ribbon cable.
  • Page 194 Main Fuse on the Battery PCA, and then through separate wires to the Power PCA for distribution to the rest of the unit. The Battery PCA also detects whether the installed battery is a Philips approved battery or not. It does this with a microswitch on the battery PCA, which detects if a dimpled recess is present in the end face of the battery.
