2 Patient Safety Pulse oximetry is a non-invasive method of monitoring the oxygen saturation of arterial blood. Pulse oximeters display oxygen saturation of functional hemoglobin and therefore the accuracy may be interfered with by carboxyhemoglobin or other dyshemoglobins present in significant concentrations. Oxygen saturation monitoring is intended to be used in a variety of clinical situations, including, but not limited to respiratory therapy, anesthesia, intensive care, and emergency.

4 Summary of Operation This section gives a brief description of the operation of the Model 515B/C monitor. For more detailed information refer to the Model 515B/C User’s Manual (Cat. No. 6500-23/6550-23). 4.1 Turning the monitor ON/OFF The key controls powering the monitor on and off. To charge the battery from AC mains ensure that the power cord is connected and plugged into a hospital grade three prong outlet. Set the rear panel power switch to | (ON).
4 Summary of Operation Adjusting Volume Levels To activate auto alert limits press and hold either the key for saturation, or the key for pulse rate. The monitor will temporarily display the new upper, then lower limits on the saturation or pulse rate display, depending upon which limits were set, then return to normal operating mode. 4.4 Adjusting Volume Levels Both pulse beep and alert volume can be separately adjusted.
5 Electronic Theory of Operation The electronic theory of operation of the Model 515B/C Pulse Oximeter is detailed in the subsections below. Refer to Section 13, Schematics and Assembly Drawings, on page 63 for schematics and assembly prints. 5.1 2532/2725 Power Supply Board The Power Supply Board contains the circuitry needed to charge the battery from the AC Mains (line voltage). The monitor may be supplied with either the 2532 or the 2725 power supply board.
5 Electronic Theory of Operation Main Board Q1 is biased off by R1, R2, and D3. This prevents the battery from trying to power the battery charger regulator. The output of switching regulator IC1 pin4 is rectified and filtered by D4, C4, and L1, then fed to the battery through current sense resistor R3 and fuse F302, to J302 pin 1 (VBAT+). The battery float charge voltage is maintained at 13.2 volts except for fast charge that is regulated at 14.4 volts.
Electronic Theory of Operation Main Board 5 IC4 pin 5 low, biasing Q2 on (page 4 on schematic). With Q2 on, Q8 and Q10 will be biased off, shutting down IC17 which turns the monitor off. 5.2.2 Power Supplies and Voltage References See page 4 on schematic. The 5 volt supply VDD is regulated by IC18, a low dropout regulator. The -VA supply is generated by IC19 from the LEDPWR supply. This supply is synchronized to front end timing signals by the SYNC line via C82, R127, R120, D35, and Q7.
5 Electronic Theory of Operation Main Board (no connection between IC28c pins10 and 11) except as noted above for the switch at IC28b pins 6-8. As a result, the IC21b pin 7 voltage passes undisturbed to the high pass filter consisting of R70 and C28. The ASAMP* signal is active low whenever either sensor LED is turned on. This causes Q5 to turn off and the signal at C28 passes through to IC21a pin 3. The ASAMP* line returns to a logic high when neither LED is being driven, causing Q5 to turn on.
Electronic Theory of Operation Main Board 5 The CS5503 converter continuously samples its input, converts the value to a digital word, puts the word in its output buffer (overwriting previous buffer contents), then repeats the process by again sampling its input. The frequency of the sample/convert/overwrite-buffer sequence is based on the 3.2768 MHz clock signal at the ADC pin 3 (ADCCLK) input. The microprocessor starts a read cycle of the Infrared channel by bringing IC23 pin 16 (ADCIRCS*) low.
5 Electronic Theory of Operation Main Board signals control the sensor LED drive and the photodiode’s return path circuitry during normal operation and calibration. The RESET and SC1 lines control when the outputs of IC13 are active, both these lines must be low in order for IC13 to operate normally. The RESET line controls IC13 during power up, while the SC1 line is under processor control and will toggle when a probe off patient alert exists and during the power up self test. Signal 5.2.
Electronic Theory of Operation Main Board 5 BATLEV1: Battery Level 1 The monitor’s battery voltage is divided down by R94 and R106. The voltage at IC25 pin 1 is monitored, and if its magnitude is less than a predetermined value (encoded in the software) the monitor indicates a low battery warning. BATLEV2: Battery Level 2, this signal is not used as of this writing. LINEST: The LINEST line from the power supply is divided down by R94 and R106.
5 Electronic Theory of Operation Main Board After all three ADCs have been read, the CPU sets the AA1 and AA0 decode lines to exert the internal TEND signal and set the 8-bit ADC to the next channel (so that it has time to settle before the next read of the ADC). This re-enables the CPUINIT line. At this point the CSI/O controller is reset awaiting an INT5MS pulse to begin the cycle again. 5.2.11 Microprocessor and Memory The Model 515B/C is controlled by IC1, an 8 bit microprocessor running at 6.
Electronic Theory of Operation Main Board Name 5.2.13 5 Function PORT2WR Port #2 Write Controlled by the WR* line and PORT2CS* from IC11. This line will enable writing to IC14. The 20 bit A/D converter CAL line, front panel LEDs, and power off control are handled by IC14. RDKEY* Read Keypanel The KEYS* and RD* control this line that enables IC5 to read the keypanel for key depressions and the configuration header J406.
5 Electronic Theory of Operation Signal PWROFF 5.2.15 Main Board Description Turns the monitor off, under processor control. Displays The front panel visual interface is made up of LEDs, the only exception is the Model 515C graphic display (an LCD DOT matrix). Both saturation and pulse rate displays consist of three seven segment displays with decimal points (for a total of six displays). The signal bar is a 10 segment LED array, the remaining indicators are LEDs. See page 2 on schematic.
Electronic Theory of Operation Main Board 5.2.17 5 Keypanel and Configuration Header The processor continually scans the keypanel for a key depression, see page 2 on schematic. The keypanel inputs enter the board at J402, these inputs are tied high by pull up resistors R33-40. When a front panel key is pressed the appropriate line is brought low. When a key is pressed the corresponding input to IC5 is brought to a logic low, this is then transferred to the appropriate output pin.
