Pulse Oximeters

Choice M Med Finger Pulse Oximeter provides exceptional quality and performance in a small, robust design. 

The devices are commonly used to measure oxygen saturation levels and pulse measurement, to advise if oxygen supply is required and determine heart rate.


It is suitable for use on adults as well as paediatrics in a variety of applications like GP surgeries, Clinics, Dental surgeries, Ambulances, Hospitals, Homecare through to spot-checking before, during and after exercise.

Pulse oximetry is a noninvasive method for monitoring a person's oxygen saturation. Peripheral oxygen saturation (SpO2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (SaO2) from arterial blood gas analysis.

But the two are correlated well enough that the safe, convenient, noninvasive, inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use.
The most common approach is transmissive pulse oximetry. In this approach, a sensor device is placed on a thin part of the patient's body, usually a fingertip, earlobe, or an infant's foot. Fingertips and earlobes have higher blood flow rates than other tissues, facilitating heat transfer. 

The device passes two wavelengths of light through the body part to a photodetector. It measures the changing absorbance at each of the wavelengths, allowing it to determine the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) nail polish.
Reflectance pulse oximetry is a less common alternative to transmissive pulse oximetry. This method does not require a thin section of the person's body and is well suited to a universal application such as the feet, forehead, and chest, but it also has some limitations. Vasodilation and pooling of venous blood in the head due to compromised venous return to the heart can cause a combination of arterial and venous pulsations in the forehead region and lead to spurious SpO2 results. Such conditions occur while anaesthesia with endotracheal intubation and mechanical ventilation or in patients in the Trendelenburg position.
