Measurement and Information
5.1 Overview
Continuous non-invasive pulse SpO
2
oximetry is employed for SpO
2
measurement. It measures the luminous flux of light of specific wavelength emitted by
the luminous light source of SpO
2
probe after absorption by oxyhemoglobin in the
patient’s tissue and arrival at the photoelectric detector, thus to obtain SpO
2
and PR.
This oximeter has been calibrated to display functional SpO
2
.
The oximeter provides:
1. Time
2. Bluetooth connection state
3. Battery level
4. SpO
2
: The percentage of oxyhemoglobin in total hemoglobin.
5. PR: The detected number of pulses per minute.
6. Bar chart: The amplitude of bar chart represents the level of pulse strength.
7. PI: Perfusion index.
8. Measurement duration: Records the duration of measurement.
9. Main unit operating state: The current state of the main unit.
10. PR measurement trend graph
11. SpO

measurement trend graph
12. Pulse wave
13. ID: User’s ID code (where applicable)
Statement: All waveforms displayed have been normalized.
5.2 Safety Information
WARNING
When the patient has the hypoxia tendency, the blood sample should be
analyzed so as to completely know the patient’s condition.
Avoid using the oximeter when MRI equipment is used; otherwise, the
