Pulse oximeter (SpO2 or pulse oximeters) are non-invasive medical devices to measure continuous heart rate but also the rate of oxygen saturation of hemoglobin in the capillaries (pulse oxygen saturation or SpO2). These devices have many applications in pulmonology, anesthesia and especially in emergency medicine.
Oximeters are provided with a sensor consisting of a transmitter part and a receiver part. The sensor will emit two kinds of light (red light and infrared light). In contact with the pulsatile blood flow each of these two more or less light will be absorbed, depending on the type of hemoglobin met. The highly oxygenated hemoglobin (oxyhemoglobin or) preferably absorbs infrared light. Hemoglobin oxygen lightly loaded (or deoxyhemoglobin) preferably absorbs red light. By analyzing the light receuillies by the receiver determines the rate oximeter oxygen saturation of hemoglobin and displays the results (quasi-continuous) on the monitor.
Many of the oximeter monitor is integrated in the sensor. The size of the device is reduced and transport facilitated. On the other oximeter monitor is separated from the sensor and is connected thereto by a cable. The bulk of these models is most important, but their big advantage of being more versatile. In fact, the sensor is then often detachable and can be connected on the same monitor a sensor adapted to the patient (adult sensor, sensor pediatric, neonatal sensor).
Precautions:
Avoid using a Pulse oximeter in the presence of strong light (direct sunlight or under a strong lamp) because it can disrupt the infrared sensor and give erroneous results. If necessary cover the oximeter to protect it from light.
Do not put a pulse oximeter on one hand, if a monitor is already placed on the corresponding arm. Contraction / relaxation of the blood pressure cuff distort the measurement of pulse oximeter.
Most oximeters are not waterproof, so do not immerse in any liquid.
