Types of SpO2 Sensors
The accuracy of the SpO2 readings will depend on the type of pulse oximeter probe you use, meaning it’s crucial to choose a suitable one. Here are the most common sensor types:
- Neonatal SpO2 sensors: In addition to the saturation number, neonatal SpO2 sensors can check sinus arrhythmia.
- Infant SpO2 sensors: They check the oxygen saturation levels in infants and plethysmographic waveforms.
- Pediatric SpO2 sensors: Pediatric SpO2 sensors check oxygen and heart rate for neonates, babies, or children. Place this sensor on the toes or fingers. The child’s weight can help determine if the sensor is suitable for use on the patient.
- Adult SpO2 sensors: They are used in adults to measure arterial blood and pulse rate.
The sensors are categorized into the following groups:
- Disposable SpO2 sensors: Perfect for single-patient use, these sensors are widely used in emergency rooms, operating rooms, ICU, NICU, or hospital wards where patients need continuous monitoring. They help prevent cross-contamination and provide comfort to patients.
- Reusable SpO2 sensors: These can be used multiple times or on different patients. They are easy to clean and disinfect, hence reducing cross-contamination.
Some new generation pulse oximeters have sensors capable of connecting to a smartphone through Bluetooth. The sensor measures blood saturation and pulse rate and transfers the data wirelessly to your phone.
The pulse oximeter uses a cold light source that shines a light through the fingertip, making the tip appear to be red. By analyzing the light from the light source that passes through the finger, the device is able to determine the percentage ofoxygen in the red blood cell.
PULSE OXIMETER quickly measures SpO2 levels, blood oxygen saturation levels, pulse rate, perfusion index (PI), which helps to better understand the …
