APK offers a broad portfolio of SpO2 sensors, including both reusable and versions for different applications and Patient categories. The principle of pulse oximetry was developed by Nihon Kohden researcher Takuo Aoyagi in the early 1970s. Pulse oximetry measures blood oxygen saturation (SpO2) non-invasively with an infrared sensor on the fingertip. Before that, the measurement of blood oxygen saturation required arterial blood sampling. Thanks to pulse oximetry, the critical parameter of SpO2 can be measured painlessly, continuously, and in real-time. If you want to find professional and reliable SpO2 sensor suppliers, look no further than APK Technology.
SPO2 Sensor Working Principle
How is SpO2 probe working? The reusable SpO2 sensor is mainly composed of a connector, cable, and sensor.
SPO2 Sensor Uses
Intended to be used on corresponding parameter monitors or pulse oximeters by healthcare professionals to collect and transfer the SpO2 and pulse rate signals of the patient.
Plug the sensor SpO2 into the monitor and verify proper operation as described in the manual.
Select a proper contact position of the patient for the sensor, the preferred position is the index finger, alternative recommends the thumb or little finger.
Reference to the instructions as below, the patient finger must be inserted correctly to the end of the sensor.
The cable of the SpO2 sensor should be placed along the patient's dorsal side and parallel to the arm.
