This is the Patent design of oximeter, which features parameters: SPO2, PR, PI

PI Indicator: Perfusion Index. It reflects the amount of blood flow being measured by the oximeter. A health care professional tests blood flow to establish norms and aid in identifying changes in a patient’s condition.
Colored display: Two colors OLED display
Multi-direction display: Rotatable multidirectional display. 4 directions, 6 modes, allow you to view your results in any direction.
Alarm function: Set the alarm and beep according to your needs. There will be a warning once the measured values go beyond the setting. Know it immediately.

SpO2 measurements may be adversely affected in the presence of high ambient light. Shield the sensor area if necessary
The following will cause interference to the testing accuracy of the Pulse Oximeter:
- High-frequency electrosurgical equipment
- Placement of the sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
- Patients with hypotension, severe vasoconstriction, severe anaemia or hypothermia -The patient is in cardiac arrest or is in shock
- Fingernail polish or false fingernails may cause inaccurate SpO2 readings
