  • Page 34: Theoretical Principles

    Theory of Operations Theoretical Principles The monitoring system uses pulse oximetry to measure functional oxygen sat- uration in the blood. Pulse oximetry works by applying a Nellcor™ sensor to a pulsating arteriolar vascular bed, such as a finger or toe. The sensor contains a dual light source and a photodetector.

  • Page 35: Automatic Calibration

    Functional Testers and Patient Simulators Some models of commercially available bench top functional testers and patient simulators can be used to verify the proper functionality of Covidien Nellcor™ monitoring systems, sensors, and cables. Reference the individual testing device's operator's manual for the procedures specific to the model of tester used.

  • Page 36: Unique Technologies

    Theory of Operations While this will not affect use of the simulator for verifying system functionality, displayed SpO measurement values may differ from the setting of the test device. For a properly functioning monitoring system, this difference will be reproducible over time and from monitoring system to monitoring system within the performance specifications of the test device.

  • Page 39: Satseconds™ Alarm Management Parameter

    System Features SatSeconds™ Alarm Management Parameter 3.7.2 The monitoring system monitors the percentage of hemoglobin binding sites saturated with oxygen in the blood. With traditional alarm management, upper and lower alarm limits are set to alarm at specific SpO levels. When the SpO level fluctuates near an alarm limit, the alarm sounds each time it violates the alarm threshold.

  • Page 40: Figure 3-4. First Spo 2 Event: No Satseconds Alarm

    Theory of Operations First SpO Event Consider the first event. Suppose the SatSeconds alarm limit is set to 25. The patient’s SpO drops to 79% and the duration of the event is two (2) seconds before saturation again exceeds the lower alarm threshold of 85%. 6% drop below the lower alarm limit threshold x 2 second duration below the lower threshold 12 SatSeconds;...

  • Page 41: Figure 3-5. Second Spo 2 Event: No Satseconds Alarm

    System Features Second SpO Event Consider the second event. Suppose the SatSeconds alarm limit is still set to 25. The patient’s SpO drops to 84% and the duration of the event is 15 seconds before saturation again exceeds the lower alarm threshold of 85%. 1% drop below the lower alarm limit threshold x15 second duration below the lower threshold 15 SatSeconds;...
  • Page 42 Theory of Operations Third SpO Event Consider the third event. Suppose the SatSeconds alarm limit is still set to 25. During this event, the patient’s SpO drops to 75%, which is 10% below the lower alarm threshold of 85%. Since the patient’s saturation does not return to a value over the lower alarm threshold within 2.5 seconds, an alarm sounds.

  • Page 43: Oximax Spd™ Alert Parameter

    System Features The SatSeconds Safety Net The SatSeconds “Safety Net” is for patients with saturation levels frequently below the limit, but not staying below the limit long enough for the SatSec- onds time setting to be reached. When three or more limit violations occur within 60 seconds, an alarm sounds even if the SatSeconds time setting has not been reached.

  • Page 44: Figure 3-7. Clinically Significant Desaturation Patterns

    Theory of Operations Figure 3-7.  Clinically Significant Desaturation Patterns The SPD parameter detects patterns of desaturation in adults that are indicative of repetitive reductions in airflow through a patient's upper airway into the lungs. Rel- ative reductions in a patient's minute ventilation over a period of time may cause a progressive drop in alveolar partial pressure of oxygen, leading to arterial desat- uration.

  • Page 45: Pulse Rate Delay Alarm Management Parameter

    System Features When the indicator reaches capacity, indicating the SPD limit has been reached, an audible alarm sounds and an alarm warning flashes. The default setting of one (1) is the most sensitive to desaturation patterns and results in more frequent alarms. For less frequent alarms, use a less sensitive setting of two (2) or three (3).
