How do We Review Pulse Oximeters for Sale

After we decided to carry finger pulse oximeters in our website, our first tasks were to research the market, understand what customers wanted and determine what were available. After some studies, we decided that people wanted quality, values, and options. We compared and reviewed pulse oximeters from various brands and offer you what we believe to be the best.

A pulse oximeter is a medical device and accuracy is of paramount important. Since we do not have expensive equipment to do appropriate technical testing, we rely on FDA approval to assure the device effectiveness and safety. Our review focuses on usability and manufacturing quality. We select 5-20 units from each model and perform the following tests on them:

• Visual inspection
• Accuracy and consistency
• Ease of use
• Features

Visual Inspection: We look for construction defects. A well-built unit is normally a sign of good overall product quality. The following pictures show examples of shabby constructions:

Accuracy: We take measurements (SpO2 and pulse rate) for each unit and compare the readings with others to determine if the readings are within tolerance. If we find one or more readings that fall outside of the limits, the model is rejected.

In one particular case, a model was rejected because one unit had a SpO2 reading of 94% while all others had readings of 97% to 99%.

Ease of Use: We try the units ourselves and also ask the opinions of others regarding ease of use. Because of the nature of this product, it has not been a major issue for all models.

Functionalities: We test all the features specified in the owner's manual and make sure that they work well.

After a model passes these tests, we compare its cost and features with others on the market. We also look at the manufacturer's reputation, manufacturing capacity and other issues before we make a decision of selling the model on our website.
