Disposable SPO2 Sensor User Manual

Intended Use & Indications for Use

The disposable SpO2 sensors are indicated for continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin(SpO2) and pulse rate(PR).

They are fully compatible replacement sensors intended for use with major brands of pulse oximeter. The SpO2 sensors are designed to match the specifications of the original equipment manufacturer, therefore ensure the appropriative sensor model number is selected for a particular pulse oximeter technology.

The models of disposable sensors suit for the following patients size:

  1. Adult (weight greater than 40 kg)
  2. Pediatric (10-50 kg weight)
  3. Infant (3-20 kg weight)
  4. Neonate (weight less than 3 kg)

Principle of Operation

The sensors shall be connected with its corresponding monitor. Oxygenation of blood is measured by detecting the infrared and red light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient's finger. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions.

Installation/Utilization/maintenance

  • Connect the sensor cable to the adaptor cable that fits your oximeter. Then turn on the oximeter and verify proper operation
  • Select the sensor site on the patient. The preferred sensor sites are the index finger for adult and children, the great toe for infants, and on the foot below the toes for neonate.
  • Apply the sensor on the patient:
    • Position the emitter and detector directly opposite each other.
    • Apply the sensor firmly but not too tightly.
  • Visually monitor the sensor site to ensure the integrity of the skin.
