User & Service Manual
Natus Quantum Amplifier
73
13. Pulse Oximeter
NOTE:
Refer to the Instructions for Use for any pulse oximeter sensors prior to use.
The following topic lists the specifications for the Nonin Oximeter sensor that is used with the Quantum or
Quantum 64 breakouts. The Quantum Amplifier provides power and isolates the oximeter from the main
power and ground.
The user of this medical equipment can verify the operation of the pulse oximeter by appropriately
applying the proper sensor, and viewing the displayed SpO2 signal and pulse rate display using the
NeuroWorks/SleepWorks
software. The
NeuroWorks/SleepWorks
software currently provides two types
of SpO2 data: a 4 beat averaged pulse rate based on the previous four continuous acceptable pulse
rates, and a beat to beat pulse rate value which is calculated based on the previous beat.
NOTE:
The SpO2 and pulse rate waveforms are not normalized.
13.1. Pulse Oximeter Specifications
Pulse Oximetry Specification
Displayed Oxygen Saturation Range (SpO2)
0 to 100%
Displayed Pulse Rate Range
18 to 321 beats per minute (BPM)
13.2. Pulse Oximeter Instruction for use
The indication of a signal inadequacy and/or probe faults for the SP02 sensor is alarmed through the
Neuroworks 9.0 software and is displayed on the computer monitor. Software will indicate the following if
an anomaly, signal degradation, or probe fault is noted during monitoring:
1. Oximeter Event, notes the time of the event and is recorded
2. Pulse rate Event, notes the time of the event and is recorded
3.
“Channel Off” indication
4. Low Quality
5.
“-----” indication if the probe is misaligned or is not receiving a signal.
13.3. Pulse Oximeter Accessories
Oximetry Sensors: Measure the light absorption of blood from two light emitting diodes
(LED’s). Oxygen
saturated blood absorbs light differently compared to unsaturated blood. The amount of light absorbed by
the blood is used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood.
The Nonin Xpod pulse oximeter may be connected to the Quantum or Quantum 64 breakouts, providing
oxygen saturation (SpO2) and pulse rate information via the NeuroWorks/SleepWorks software.
Reusable and disposable Nonin pulse oximeter sensors may be used with the Nonin Xpod device. A list
of commonly used sensors is shown below.
