What is a pulse oximeter? Why use a pulse oximeter?

Pulse oximeter is often called finger clamp pulse oximeter, finger pulse oximeter, pulse oximeter, oxygen saturation detector, etc.
It is used to monitor the peripheral blood oxygen concentration, play a monitoring role, and monitor changes in the condition. It is commonly used for hypoxia caused by respiratory diseases. Frequently used is the pulse oxygen at the fingertips of the fingers. Its normal value is recommended to be above 90%, and above 93% is the best. If it is below 90%, it indicates that the patient has severe hypoxia. At this time, the arterial blood gas oxygen partial pressure does not refer to the oxygen saturation of oxygen, and the oxygen partial pressure value is basically about 60%, so this is a state of multiple hypoxia. Patients with severe pneumonia or chronic obstructive pulmonary disease, as well as those with recurrent respiratory failure, can choose monitoring. It includes some patients with sleep apnea, who are treated with respirators, and who are monitored with pulse oximeter.
Main advantages of finger clamp pulse oximeter
Compact and portable, with high accuracy, moderate price, easy operation, and no difficulty for middle-aged and elderly people. It belongs to Class II hospital equipment and is a brand with a registration certificate, with high credibility. There are various options on the market now, and the most popular one is blood oxygen monitoring for watch tests. In fact, many buyers have been taken away and must check if they have medical qualifications (Class II medical device registration certificate).
