Pulse oximeter is one of the most widely used anesthesiology devices in medical diagnostics. It is applied for monitoring a person’s oxygen saturation of hemoglobin of capillary arterial blood.
The device becomes extremely necessary in case of hypoxia, the disease that is characterized by the lack of oxygen. If a person suffers from hypoxia, the pulse oximeter should be used almost constantly to avoid complications during treatment and diagnostics.
The special feature of the device is noninvasive (without physical interference) measurement method. The blood oxygen content is measured with a photosensor and two light sources (red and infrared). The degree of light absorption depends on blood saturation with oxygen, which is the basis of the functioning of the device.
The only difference between all devices is their mobility, which naturally affects the overall functionality. Accordingly, two types of this medical equipment can be distinguished:
Besides, there is a classification based on the patients’ age. Regular pulse oximeters are designed for both children and adults and are considered standard. The equipment for newborn babies has a number of particular advantages: weighs less, is equipped with a special lock and an alarm probe for notification of the medical staff in case of a significant decrease in the level of oxygen in the blood.
One should remember about the special sensitivity of these devices. The bright light, shivers and sharp movements can affect the accuracy of measurement. Moreover, various dyes, which include nail polish, can significantly reduce saturation rates, thus depriving the doctors of the opportunity to make an accurate diagnosis timely and precisely.
The price of pulse oximeter can be as low as 100 USD or less, while the newest, high-tier systems may cost as much as 1000 USD. Well-known brands of insulin infusion pump in the United States are Better, Nellcor and Datex Ohmeda. Outside of the US, top-selling brands are Masimo and Mindray. Besides, one should understand that new and demo machines will cost more than refurbished or used pulse oximeter for sale. What is the difference? New machines have never been used. They have the manufacturer’s warranty. Demo machines are, as a rule, exhibition models. They have not been used in clinical practice but they have been often presented at exhibitions. As a result, the pulse oximeter price is lower. Refurbished machines are used machines that have undergone improvements (refurbishment can be done at the manufacturer’s facilities or in private repair shops)
