Do oximeters need to be expensive?

The oximeter is an instrument for measuring the oxygen saturation of human blood, which is often used in hospitals, athletes, mountain explorers and other people. There are generally two types of oximeters: pulse oximeters and non-pulse oximeters.

Pulse oximeters measure blood oxygen saturation by detecting pulse waves from fingers, toes, or pinnae. They are generally small, portable, and suitable for everyday use. However, the measurement accuracy of the pulse oximeter may be affected by factors such as respiratory rate, finger pulse state, temperature, humidity, etc., so it is not suitable for clinical testing.

Non-pulse oximeters measure blood oxygen saturation through optical principles. They generally have higher measurement accuracy and are suitable for clinical testing, but are bulky and inconvenient to carry.

The price of an oximeter is generally related to factors such as brand, model, and function. You don't have to buy expensive ones, you can choose the right oximeter according to your needs and budget.

The choice of oximeter should also consider its function. Oximeters on the market generally have functions such as displaying blood oxygen saturation, heart rate, and respiration rate, as well as supporting Bluetooth connection, data recording, and electronic reporting. For an oximeter for daily use, it is enough to display the blood oxygen saturation; for professionals or people with special needs, you can consider purchasing an oximeter with more functions.

Besides price and features, there are a few other factors to consider. For example, the convenience, accuracy, quality, and after-sales service of the oximeter. When purchasing an oximeter, you should start from many aspects, comprehensively consider various factors, and then make a decision.
