Pulse Oximeter Review Article Text

Jonathan Friesen - Writing Coach

published: 16 july 2015 pulse oximetry is universally used for monitoring patients in the critical care setting. This article updates the review on pulse oximetry that was published in 19 in critical care. A summary of the recently developed multiwavelength pulse oximeters and their ability in detecting dyshemoglobins is provided. The impact of the latest signal processing techniques and reflectance technology on improving the performance of pulse oximeters during motion artifact and low perfusion conditions is critically examined. Finally, data regarding the effect of pulse oximetry on patient outcome are discussed. This is an open access article distributed under the terms of the creative commons attribution license pulse oximetry is ubiquitously used for monitoring oxygenation in the critical care setting.

By forewarning the clinicians about the presence of hypoxemia, pulse oximeters may lead to a quicker treatment of serious hypoxemia and possibly circumvent serious complications. In this review, i update the principles of pulse oximetry from my article in 19 and discuss recent technological advances that have been developed to enhance the accuracy and clinical applications of this monitoring technique 1 . Finally, available studies evaluating the impact of pulse oximetry on patient outcome will also be reviewed.

6 comments usually those things don t really work for exercising you have to stand still as a stone for it to read anything not good for cycling, running, swimming basically good for nothing nothing in this article says any different accurately measures oxygenation while in motion ok seeing is believing. These things have been around 40 years they are ok for lying in a hospital bed not for exercising wle 4th january, 2013 @ a.m. California time this might be a convenient device but working against it are the following issues: 1 cost. Really outrageous, considering its just a finger tip sensor and old style cable 2 most times sao2 is needed in a continuing readout.

Packaging several separate devices into one unit has serious drawbacks eg, if the phone dies, so does the sao2. 4 the ready availability of dedicated 'finger clip on' sao2 devices for as low as $30 represents serious competition. California time madrummond knows for a fact that it works when you move, because go ahead and google ' mike drummond masimo' and you'll see he's their pr guy. At least i can look right at my finger and not have to deal with a bunch of cables that way. California time is it worth paying an extra $200+ for a masimo's measure through motion technology, and b the ability to sync with your iphone? jamal el jamal 31st january, 2014 @ a.m.

California time 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. These new entries are significantly cheaper than those from nonin as much as 50 70%. 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.

Which one is the best pulse oximeter? we have designed multiple experiments and asked an independent testing lab to perform the experiments for us. Remember that a bad reading at outside normal operating range does not mean the oximeter is bad. We have just received the final report from the testing lab and completed the last article in the series. 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. 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. Signal strength for a normal healthy adult is around 5% 6% level 0.3% signal strength is very low.

The motion test was inconclusive however the nonin oximeters appeared to have an edge. According to our research, masimo pulse oximeters have outstanding record in very low perfusion and motion situations. Of all the oximeters, only md300c63 displays the plethysmograph, which provides important information related to your blood flow. 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.

We selected four different oximeters for the study: nonin onyx 9500, nonin go2 achieve, choice md300c1 and choice md300c63. The nonin oximeters are purchased for $200 and $100 respectively from an internet store we obtained the choice oximeters from our inventory and they are listing at $65 and $109 at the time of this writing. The simulator can simulate many clinical conditions, such as high pulse rate, poor blood circulation, low sp02 saturation, motion. These four oximeters were sent to the testing lab for the experiments the simulator is an expensive equipment and we cannot afford to purchase one. we are not testing for the accuracy of individual oximeters as this would require arterial blood samples with sao2 measured using a laboratory co oximeter. The cost will be prohibitive and our sample size would be too small to draw any conclusion. Our objective is to compare them. furthermore, the biotek simulator is not designed for testing accuracy.
