START-UP AND USE Basic Operation Alarms Trend Data Battery Operation Disposal of Device Components Performance Considerations BASIC OPERATION WARNING: The NPB-290 is a prescription device and is to be operated by qualified personnel only. WARNING: Do not lift the monitor by the sensor cable or power cord because the cable or cord could disconnect from the monitor, causing the monitor to drop on the patient. WARNING: The NPB-290 is intended only as an adjunct in patient assessment.
Start-Up and Use Ensure that the voltage selector switch on the rear panel is set to the proper voltage. Power-On Self-Test (POST) WARNING: Ensure that the speaker is clear of any obstruction. Failure to do so could result in an inaudible alarm tone. 1. Plug an appropriate Nellcor sensor firmly into the MC-10 or SCP-10 and lower the MC-10 or SCP-10 sensor lock over the sensor connector until it clicks into place. Insert the MC-10 or SCP-10 into the NPB-290 sensor port.
Start-Up and Use the numbers and have them available prior to requesting technical assistance. 5. If the NPB-290 detects an internal problem during the selftest, an error tone sounds and the monitor displays an Error Code and corresponding number (see the Troubleshooting section). 6 Upon successful completion of the self-test, the NPB-290 sounds a 1-second tone indicating that the monitor has passed the test. WARNING: If you do not hear the POST pass tone, do not use the monitor.
Start-Up and Use Monitoring During monitoring, the NPB-290 displays SpO2 and pulse rate readings with each pulse beat. %SpO2 is displayed for values between 0% and 100%. Pulse rates are displayed for values from 20 to 250 beats per minute, and for zero beats per minute. Note: Pulse rates below 20 (except zero) are displayed as 20, and pulse rates above 250 are displayed as 250. A pulse rate of zero is used to indicate that the monitor is not monitoring a pulse.
Start-Up and Use At Initial Power-Up Immediately after the NPB-290 displays its software version numbers and POST is completed, the monitor enters Pulse Search (the Pulse Search indicator lights), if a sensor is properly connected to the monitor. During this Pulse Search, the display reads zeroes while the monitor searches for a valid pulse. When a valid pulse is detected, the NPB-290 begins monitoring.
Start-Up and Use ALARMS Description of Alarms The NPB-290 has three levels of audible alarms. 1. High-priority alarm: Indicated by a fast-rate, high-pitched, pulsing tone. A high-priority alarm sounds after loss-ofpulse is detected. Refer to the “Management of the Loss-of-Pulse Alarm” paragraph later in this section for a detailed description of the loss-of-pulse alarm. 2. Medium-priority alarm: Indicated by a medium-rate, medium-pitched, pulsing tone.
Start-Up and Use Adjusting Alarm Limits WARNING: Each time the monitor is used, check alarm limits to ensure that they are appropriate for the patient being monitored. Overview When the NPB-290 is first powered on, alarm limits are set to their power-on default values. Power-on default alarm limits can be changed by qualified service personnel, using the instructions described in the NPB-290 service manual. You can temporarily change alarm limits from their default values if necessary, as described below.
Start-Up and Use To view the current lower alarm limit value for SpO2, press the Lower Alarm Limit button. The number displayed in the %SpO2 field represents the current SpO2 lower alarm limit. A series of dashes are displayed in the Pulse Rate field. Since the parameter being displayed is a lower limit, these dashes appear in the lower portion of the Pulse Rate display, as shown: To view the current upper alarm limit value for Pulse Rate, press the Upper Alarm Limit button twice.
Start-Up and Use To change an existing alarm limit, first enter the viewing mode for that value, as described earlier in “Viewing Current Alarm Limits.” Once the value you wish to change is displayed, press the Adjust Up or Adjust Down button to adjust the value as needed. Alarm Limits Changed Indicator If alarm limits are changed from the NPB-290’s power-on defaults, a decimal point appears after the displayed value, during patient monitoring, or when alarm limits are viewed.
Start-Up and Use Viewing Current Alarm Silence Duration To view the current audible alarm silence duration, press and hold the Alarm Silence button for less than 3 seconds. The display will show the current duration in seconds, as shown: To adjust the audible alarm silence duration, while holding down the Alarm Silence button, use the Adjust Up or Adjust Down button to set the duration to 30, 60, 90, or 120 seconds, or OFF (Alarm Silence mode).
Start-Up and Use Alarm Silence Reminder The alarm silence reminder (three beeps) sounds at least every 3 minutes while the alarm silence duration is set to OFF. The alarm silence reminder may also be disabled by service personnel using the procedures described in the service manual. The factory default is that the reminder is enabled.
Start-Up and Use alarms are distracting and potentially time-consuming. However, if interference persists, an alarm should notify the attendant. The NPB-290 loss-of-pulse alarm is designed for use in environments in which the pulse can be obscured by interference. Most loss-of-pulse alarms are attributable to interference from patient motion, which typically is brief.
Start-Up and Use SPORADIC OR LOST PULSE WITH CONTINUOUS MOTION Low priority alarm sounds Pulse Search Indicator lights continuously Pulse Search Indicator flashes %SpO2 and Pulse Rate Displays alternate between previous display and dashes Zeros displayed Motion Indicator lights continuously* 0 seconds 10 seconds 60 seconds 50 seconds SPORADIC OR LOST PULSE WITHOUT CONTINUOUS MOTION High priority alarm sounds Pulse Search Indicator lights continuously Pulse Search Indicator flashes %SpO2 and Puls
Start-Up and Use During that data evaluation period: • If the patient is not moving (for example, because of cardiac arrest, shock, paralysis, anesthesia) and has no qualified pulse for 6 seconds, a high-priority alarm immediately sounds, the Pulse Search indicator flashes, and the data displays flash zeroes. • If the patient is constantly moving, the NPB-290 searches for qualified pulses for up to 50 seconds. Each time a qualified pulse is detected, even during motion, the data displays are updated.
Start-Up and Use Nurse Call Feature WARNING: The nurse call feature should not be used as the primary source of alarm notification. The audible and visual alarms of the monitor, used in conjunction with clinical signs and symptoms, are the primary sources for notifying medical personnel that an alarm condition exists. The nurse call feature of the NPB-290 works in conjunction with the nurse call system of your institution when the monitor sounds an audible alarm.
Start-Up and Use To access the menu options, simultaneously press the Upper and Lower Alarm Limits buttons. Then, using the Adjust Up and Adjust Down buttons, scroll through the available menu options, as follows: #1: Trend Print. Sends the existing trend data to the NPB-290 serial port. #2: Trend Clear. Deletes the existing trend data. #3: Language Selection.
Start-Up and Use Menu Items 8 and beyond are for use only by qualified service technicians. Information about these options is available in the NPB-290 service manual. BATTERY OPERATION The NPB-290 has an internal battery that may be used to power the monitor during transport or when AC power is not available. A new, fully charged battery provides a minimum of 8 hours of monitoring time if there are no alarms or serial or analog output devices connected.
Start-Up and Use Note: As the battery is used and recharged over a period of time, the amount of time between the onset of the low battery alarm and the instrument shut-off may become shorter. It is recommended that the internal battery be replaced by qualified service personnel every 24 months. Caution: If the NPB-290 is to be stored for a period of 2 months or longer, remove the battery from the monitor prior to storage. Recharge the battery when it has not been charged for 2 or more months.

APPENDIX A: PRINCIPLES OF OPERATION Oximetry Overview OXIMETRY OVERVIEW Pulse oximetry is based on two principles: that oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light (i.e., spectrophotometry), and that the volume of arterial blood in tissue (and hence, light absorption by that blood) changes during the pulse (i.e., plethysmography).
Appendix A: Principles of Operation determine SpO2. This resistor is read when the monitor is turned on, periodically thereafter, and each time a new sensor is connected. Additionally, to compensate for differences in tissue thickness, the intensity of the sensor’s LEDs are adjusted automatically. Functional versus Fractional Saturation This monitor measures functional saturation — oxygenated hemoglobin expressed as a percentage of the hemoglobin that can transport oxygen.
