When I first got this unit, I immediately installed the included AAA batteries and tested it by holding my breath. After 1 minute of holding my breath, then breathing heavily, I saw the readings begin to decrease at around the 55 seconds mark, continuing to decrease even when I started breathing heavily again, eventually bottoming out at a 90% SpO2 reading. After 2 minutes of holding my breath (and getting really dizzy, seeing stars in my visual field), I was able to achieve a 82% SpO2 reading. With normal breathing, I used the device throughout the day and found I was always between 96-99% SpO2. I was amazed at how quickly my SpO2 recovers to above 96% when I start breathing again after the holding-my-breath experiments above. It's fully recovered within 15 seconds of when I restart breathing again. I don't have access to a calibration standard or a calibrated hospital-grade pulse oximeter, so I have no idea exactly how accurate this thing is, but it very clearly detects blood oxygen level. At the very least, it seems plausible it could detect the "silent hypoxia" that some asymptomatic SARS-CoV-2 carriers have.

The pulse ox arrived just as expected. After putting in the batteries provided, it’s ready for use!!! Simple as can be. The 2 colors make a difference when reading levels assessed by the oximeter. It’s bright, concise and clear making it very easy to read. Use couldn’t be easier!!! No fumbling with it or repositioning for a reading. I’m a nurse and in comparison to oximeters used it’s accuracy is spot on. I probably researched over 50 oximeters before deciding to purchase this one. I’m glad I chose this one. I am critical of myself often times for spending so much time on researching items I purchase. Most often it’s totally worth the time and effort put forth to do so but not ALWAYS! I feel like this meter will will provide me with often critical information that is essential to caring for others! If at some point it doesn’t meet the expectations I have for this product I will update this review. Whether you’re medical personnel or just a person with the need to monitor your loved ones, anyone can use this and feel assured that it is providing you QUICKLY with accurate information. This is my own unbiased review. This a tool everyone in need should own. At this price point, there’s no reason not to have one in your tools of the trade or medicinal armor!

Ok, I want to first want to preface this by saying that I’m a medical doctor, so I do know a thing about pulse oximeters—both in theory and in practice. I noticed the top review has a picture of the pulse ox on a stuffed animal, showing at 99%, as “proof” it is inaccurate equipment. There are a number of problems with this supposition, and it shows a basic lack of understanding of how pulse oxes work. They are equipment that are designed to measure something specific under specific circumstances of being clipped to a fingernail with no opaque polish. NOT inanimate objects like markers and stuffed animals. A pulse ox works by shooting red light across the width of one of the middle fingers. Since tissues are translucent rather than totally opaque, the amount of light that is measured at the receiving sensor measures the proportionality of absorbed red light, which equals the proportion of material that absorbs it. This is called Beer’s Law. Pulse oxes are also governed by another law called Lambert’s Law, which says the amount of light absorbed is proportional to the length of the path that the light has to travel in the absorbing substance. The third law has to do with the fact that oxygenated hemoglobin (which in itself is red) absorbs more light than deoxygenated hemoglobin. This is due to the difference in wavelengths of red and blue light (red objects absorb more red light than blue objects). This is also why the test is not accurate if you have red nail polish on or your finger is not centered and light can move around it (or if you use a tiny pinky finger, for example). You can now see why it’s totally irrelevant how using a pulse ox on an inanimate object (especially, a bright red felt tail!) with totally different properties than an index finger is not a good way to judge accuracy. That’s like saying that your kitchen scale did not work well because you threw it in a swimming pool to measure the weight of the water. Equipment is only designed to work under particular circumstances and limitations. Anyway, I purchased this pulse ox for my father. He has COPD and a bunch of other risk factors for COVID-19, so I appreciate having a heads up if his oxygen sats dip. This is a good vital sign early marker for covid because it is an unusual disease, in that it causes what doctors have nicknamed “happy hypoxia”. You can google this to find out more, but it basically means that in other pneumonias that devolve rapidly into hypoxic conditions that require ventilation, their symptoms also crash, to the point where they lose consciousness or can barely talk. Covid-19 is more insidious and can creep up on some patients, who might be sitting up in bed (yes, symptomatic, but still conscious and talking), fooling even medical professionals into thinking their cases were not too serious until it was too late. This is the reason medical professionals find pulse oxes to be useful—they measure signs of disease (objective results from testing) rather than symptoms (subjective reports of feelings from patients). It gives me peace of mind to know my father has this and can measure it daily when he does his insulin shots and measures BP. He has chronic bronchitis, diabetes, stroke history, high blood pressure, obesity, and he is nearly 80, so he’s definitely in that very high risk category. On the actual unit, it was extremely easy to set up and use. You press a button and it turns on (once you put the batteries in the right way, lol); turns off automatically. I didn’t find anything inaccurate about it... and the hardest part of it was probably getting the lanyard in, haha (I advise using a needle to get the other end out of the hole; there’s no way a senior citizen could do this alone, so please help them). I’ve used many pulse oxes in my day. The professional ones in the hospitals are about 1% more accurate than these little portable, cheap pieces of equipment that you can buy for the home. I highly recommend them for any patients or elderly who have risk factors or disease comorbidities (especially, pulmonary). These little portable ones were sold out for months during the pandemic first peak (even hospital staff had trouble getting their hands on privately sold ones), so I’m glad to have one now.

This device is easy to set up and use. It reports %oxygen saturation and pulse rate on the face of it accurately. It comes with a cord that allows one to keep the device connected around your neck. It works great in that the results are instant, easy to read, and require only 2 x AAA battery power. I like the large size of the numerals on the monitor because I can read them without my glasses. It’s nice also that the power shuts off a few seconds after use so the batteries should last a long time. The fine prints are hard to read I wish there is a video link tutorial on how to follow in a more user-friendly manner

I would like to start out saying that I am a RN who has worked in the emergency room and throughout the hospital system for over 20 years. I’ve even done home health. My mother required emergency surgery and had to have heart stents put in after going into CHF. We live over 1000 miles away so when I went up to see her, get her out of the hospital and take her home and care for her for a month at home, this is one of the items I bought. The thing about oxygen sensors is this – you can buy them anywhere. You can buy them inexpensively and you can pay a boatload of money for one. At the end of the day it doesn’t mean it’s going to be exactly correct so it’s important to find one that actually works! Fast forward, I brought this pulse ox , A manual blood pressure cuff and a scale in my luggage to my mothers house to care for her. Her fingers were freezing cold. As with any oxygen sensor, cold fingers can indeed give you a lower, false reading… if you get one at all. This pulse ox actually read my mother’s oxygen saturation with zero difficulty. I tested it on my cell as well as my mother and even the home health nurse! The home health nurse had her own pulse ox, she would have trouble getting a reading off of my mother… So we wound up using this pulse ox I got off of Amazon here. I’ve tried many throughout my years. From the highest of high tech to the ones off of the shelf at Walgreens. This by far and hands-down is the best pulse ox I have used. And for the money I paid for it? Wasn’t even that expensive. Blew my mind. I typically don’t write very many reviews but this item I highly highly suggest buying if you need to monitor your oxygen saturation It’s not expensive, it’s durable , it’s dependable, it is very easy to work. Simply put it on your finger and press one button. Even my non-tech mom can use this

I'm 72 years old. I've never smoked, but I do have a pacemaker. I had a pulmonary infection from some unknown cause that required me to take an ambulance to the ER. After they ruled out COVID-19 and heart problems the hospital simply sent me home. I had periods where I simply couldn't get my breath. I ordered the oximeter to give me some feedback on how well I was absorbing oxygen. It worked perfectly. I tried to rehab myself by taking short walks, and I had problems walking even a short block before I had to stop and get my breath. I was worried about how well my lungs were working, but using the oximeter while I was walking reassured me that my blood oxygen level was 96-99 percent. A couple of times when it got down to 95% I supplemented my breath from a canister of oxygen I got from the sporting goods store. I found it took about 90 seconds before the oximeter recorded an increase in blood oxygen. This helped me balance my effort to what I could actually do. I have both a Fitbit and a Polar chest-strap heart rate monitor. My Fitbit was showing major fluctuations in my heart rate, so I also started wearing the Polar for my walks. The two devices were showing different heart rates, but by comparing the two devices to the readout on the oximeter I was able to determine that the Polar device was malfunctioning, and once I cleaned the lights on the Fitbit, it was almost exactly comparable to what the oximeter was showing. All told, this device has been a great help in my recovery. There is a major reassurance to knowing that the chest discomfort from exercising is a result of low conditioning and that I wasn't starving for oxygen. This is a great device! My pulmonary infection went away after about 92 days. My resting heart rate went down from the upper 80s back down to a normal 71 bpm. These days my blood oxygen level reads a normal 90-99% and I trust this device to report it correctly. If it ever breaks, I will buy another just like it. The price was right (about 1/3 the price at Walgreens), it is comfortable to use, and I can see the readout clearly at a glance, even while I'm walking fast.

Due to a serious Lung Disease, I have to monitor my Oxygen Saturation several times a day so i now have 5 of these (1 in my car, 1 tethered to my Portable Oxygen Concentrator, and the other 3 are in various rooms in my house for quick easy access). I started out with one, and when i took to a doctor appt I compared it with her office unit and it consistently matched it exactly. I bought a few more, took them to various other doctor visits and they also matched theirs. I even put all 5 on various fingers on both hands to test and they all read the same, or bounce up or down a point as i move around. But they're all virtually the same across the board. I've bought a few others with an LCD Sceen for bright daylight but these were 2 to 4 points different than my 5 SantaMedical units so i returned those. I also have an Innovo Deluxe iP900AP and it's also accurate and reads the exact same. The only issue is that the OLED Screens on both brands are hard to see when outside in the sun. The LCD unit was easier to see outside but the few I tried weren't accurate so i'll just find some shade to read mine when outside. Update - they're still working perfectly, but i've noticed the battery cover on this model slides off very easily (it barely latches closed) and all 5 of mine have this issue. I think i've seen it mentioned in other reviews too. My workaround is to place a big piece of light blue painters tape on that cover extending to the top to keep the cover from sliding down, with the added benefit that i have used that tape to label each unit for the room it belongs in (Bedroom, Living Room, Kitchen). When i replace the batteries, i carefully peel the top of the tape away just enough to get the cover off, then i press it back down when i'm done so i don't have to make a whole new label.
