![]() ![]() The sample size is way too small to make any general statements however the experiment does give us a glimpse into the performance of these four particular oximeters. The experiment was conducted on ONE oximeter from each model. Of all the oximeters, only MD300C63 displays the plethysmograph, which provides important information related to your blood flow. The motion test was inconclusive however the Nonin oximeters appeared to have an edge.Īccording to our research, Masimo pulse oximeters have outstanding record in very low perfusion and motion situations. Signal strength for a normal healthy adult is around 5%-6% level 0.3% signal strength is very low. In one low signal strength test, Onyx 9500 passed all levels, while GO2, MD300C1 and MD300C63 failed to show any reading when signal strengths were at 0.1%, 0.2% and 0.3% respectively. In general, both Choice and Nonin oximeters worked equally well in all cases except under two conditions - very low blood perfusion (signal strength) and motion. The whole exercise is a learning experience for us. We have just received the final report from the testing lab and completed the last article in the series. ![]() We would report the results as they become available. Remember that a bad reading at outside normal operating range does not mean the oximeter is bad. We will push the oximeters far beyond their normal operating ranges. We have designed multiple experiments and asked an independent testing lab to perform the experiments for us. The same question keeps popping up - "are these oximeters as good as the name brand ones." We know that our products are solid based on our own testing and customer feedback however we do not know how good they are when compared with Nonin Onyx 9500 or Nonin GO2. We have served thousands of customers and sold thousands of pulse oximeters. These new entries are significantly cheaper than those from Nonin (as much as 50-70%). Nonin Onyx 9500 pulse oximeter has been very popular on the market for quite a few years and then Nonin later introduced a new lower price model GO2 Achieve to compete with newer models introduced later by other new companies. ![]()
