Deluxe SM-110 Finger Pulse Oximeter with Carry Case and Neck/Wrist Cord

As a physician I am accustomed to using a pulse oximeter in the office setting to record what we consider to be the fifth vital sign, oxygen saturation. In my work setting this is a crucial measurement to determine how worried to be about someone complaining of cough or shortness of breath. Basically, these meters quickly and painlessly determine pulse rate and oxygen saturation with no more effort required than sticking a finger tip into the meter. For years pulse oximeters have been too expensive for most people to purchase for personal usage, but the cost has obviously dropped dramatically over the years. I purchased this Deluxe SM-110 two way finger pulse oximeter on a Gold Box offer for personal usage at home. It arrived very quickly after placing my order. The meter is quite small, and arrives safely packaged in a sturdy fabric carry case. Two different straps are included (wrist strap & neck strap) and a pair of AAA alkaline batteries. The included instruction sheet tells you everything you need to know. The battery compartment is a little odd: usually, the negative end of a battery goes against the spring, but with this product the positive tip of the battery goes against one of the springs and the negative end of the battery goes against the other spring. The battery configuration is clearly imprinted in the battery compartment, so you can easily see how to orient the batteries. Operation is very simple. Push the power button to turn the unit on and stick a finger in the meter. The meter opens somewhat like a clothes pin to create the spot to place your finger. The meter blinks to show it is detecting your pulse and oxygen saturation and will display both of these values in just a few seconds on the display. The "two way display" simply means you can read pulse rate and oxygen saturation from two different directions, which is handy if you are trying to measure them on yourself. When you are done with the measurement you can take your finger out of the meter, and it will turn itself off within a few seconds. Normal oxygen saturation will be above 88% on room air (i.e. without wearing supplemental oxygen). An oxygen saturation below 88% either on room air or while wearing supplemental oxygen means you should seek medical attention right away as your oxygen level is too low. Most healthy adults with good heart/lung function will have oxygen saturation well into the 90s on room air. This is a very handy device to have around, particularly for anyone with heart disease such as congestive heart failure or lung disease such as COPD or asthma, especially if they require usage of supplemental oxygen. The cost for this pulse oximeter is minimal and well worth the investment.

This pulse oximeter is simple to use and gives quick readings. It fits comfortably on the finger and the display is clear and easy to read. Results appear within seconds, which is convenient for quick checks. The device feels well made and consistent with repeated use. Overall, it’s a straightforward, reliable oximeter that works as expected and is easy to keep on hand.

I've used a different Oximeter...the Acc U Rate ($22) for about a year now and it's number for Pulse Ox is 1 to 2 numbers lower than this silver SM-110. I put the Acc U Rate (blue model) on my left index finger and this silver one on my right index finger. The silver one gave me a 96 while the blue one rated me at 94. I'll take them both with me to Rehab and check them out against the one the pro's use and come back and let you know the score. Okay....I took both Oximeters to my Rehab exercise class today and guess which one was accurate...the silver one, the one I'm doing the review on right now. So...actually that was good news for me personally because it shows my pulse ox is at least one number higher than i've thought it was for the last year. This silver one registered the exact numbers that the professional oximeter registered for my Pulse Oxygen. The pulse rate varied just a number or two but was jumping around a bit on all 3 oximeters, and the numbers on all three oximeters were very similar. This silver oximeter was very close if not the exact number of the professional model. I tested about 3 times after various exercises and 2 times at rest. Significantly, my pulse oxygen numbers on this silver oximeter were perfectly lined up with the professional mode every timel, and I mean to the exact number. So I'll be using this silver one daily and the blue one for backup (and just add a number or two to it). Packaging wasn't great. Slow shipping. No paperwork at all, so no physical receipt. The flimsy box was bent up like something you'd get from China, with the contents just stuffed inside. Anyway, that's too bad because this is a good product that deserves better. Oh...the readout on this silver one is choppy, just look at the display on it's page, whereas the display on the blue one is much easier to read because the lines showing the numbers are all connected, if you know what I mean. Maybe what I'm trying to say is...the number display on this silver Oximeter is like what you'd see if a dot matrix printer printed it out. Best interpreted at a distance. But again...you get an accurate reading with the silver one. Another thing...this silver one doesn't 'grasp' your finger quite tight enough. And the readout is rather upside down...and you can't change that. With some oximeters you can push the button to get various directional orientations, but evidently not with this one. I guess we're supposed to put it on our index finger and then turn our hand around with our palm-side facing us and then drop-down that finger and read it. Yeah...that works. But again, it's a loose fit, a little more prone to fall off. If I could have only one oximeter, I'd get this silver one because of its excellent accuracy. You get used to the other negatives I mentioned. Almost forgot...I like the little black case that you also get a lanyard to attach to. You also get another lanyard that attaches directly to the Oximeter. It's a little too long though...hits against everything. Will have to shorten it a bit. Lastly, be sure to put the batteries in the right way. I hear if you don't the whole world could blow up. :)

This pulse oximeter has been a helpful addition to our home. It's quick to give a reading, easy to use right out of the box, and the display is clear and easy to read- even in low light. The finger clip fits comfortably and I appreciate the compact design for travel or keeping in a drawer. I’ve used it to check oxygen levels and pulse during workouts and while resting, and the numbers have been consistent and in line with expectations. It brings peace of mind, especially during cold and flu season. Overall, it’s a great tool to have on hand for general wellness tracking. Highly recommend for anyone looking for a simple, no-fuss oximeter.

My 81-year-old mother-in-law has several medical conditions, including COPD. When she has a problem breathing, it's helpful for her to know her oxygen saturation, so she knows if it's "merely" the COPD or she is having some other decline in lung function. Unfortunately she also has arthritic and perpetually cold hands, and has found that many pulse oximeters have LOTS of trouble getting a good reading on her fingers. I read through LOTS of the Amazon reviews for pulse oximeters, and any time someone said they were an EMT or a nurse AND they found that a particular unit was more likely to work in difficult situations, those items would go onto my wishlist. After awhile, this and one other moved to the top of the list to try. (I wasn't eager to have to order several before we found one that worked.) In the end I chose between two -- this one, the Santamedical SM-110, which I think must be an older model, and a seemingly newer model of the same brand Santamedical SM-240 OLED Finger Pulse Oximeter . (We have NOT ordered the SM-240.) My mother-in-law and I discussed the merits of the two and we decided to try this older, less expensive one. It arrived VERY quickly, came with a nylon case, two lanyards and AAA batteries so it was immediately usable. The box and instructions contain some amusingly strange translated English (from Chinese, maybe?) but there wasn't any huge problem understanding how to use it. My mother-in-law seems happy with it; she hasn't had any trouble getting it to read, though she does have to warm her hand and switch among different fingers, just like with the ones at her physical therapists' and doctors' offices. This SM-110 has an "old fashioned" red LED display, which I imagine might be hard to read in bright sunlight. The Sp02 reading is near one end, and the pulse is near the other end, and all the digits are quite read-ably large. When you are getting a successful measurement, the reading comes up really quickly (just a few seconds), though when it's NOT being successful, the "bar graph" next to the digits doesn't move much. I presume as my mother-in-law gains experience using it, the pulsations of the bar graph will help her position the unit for the steadiest readings. One annoyance of the design is that if her hand is flat in front of her the numbers are "upside down" to her when she is wearing it. Obviously whoever designed it imagined a caregiver using it on other people, not using it on themselves. (I believe the SM-240 addresses that issue by having the display rotated 90 degrees, so you can more easily read it merely by rotating your hand toward yourself.) While she has only had it for a week, my mother-in-law seems satisfied, so we're not going to bother ordering the SM-240. I presume if the newer model works similarly to this one it should be a good risk, too, but this SM-110 was certainly a bargain and works well. There ARE a few even less expensive pulse oximeters on Amazon and other sites, but none of the others has as consistently a high rating here as the Santamedical SM-110 and SM-240 do.

My job: Find a Christmas present for a 93 mother, who has emphysema, COPD and atrial fibrillation. She was diagnosis with pneumonia a short while ago and hospitalized. They sent her home on 24/7 oxygen. I did not like the diagnosis, nor did she, of pneumonia. The hospital tests were inconclusive too. Most of the other symptoms I could attribute the exacerbations to stress of the holiday season. She was saying that she 'walked' to the dining, while eating ran out of oxygen switched O2 tanks walked back to her apartment and found she'd forgotten to turn it on but felt fine. She also related a few other incidents. She told me she was thinking about getting one she saw in a mail order catalog, about a week before Christmas. I told her to hold off and let me look into it. I came across this one, it had a wrist strap, neck strap, bag. I thought it was darn near perfect. The price was good, so I ordered it. It arrived within 48 hours! THANK YOU AMAZON! I tried it out. My daughter tried it out. Then we wrapped it and gave it to her. She was delighted. I did have to explain certain things, like when she is sitting and it goes up, she could be causing that rise from 'nerves' and to take a deep breath and relax, calm down and the numbers would respond accordingly. She got nervous when her pulse was at 70/75 because it was too low, so I showed her mine which was at 60/65 and told her that was normal for me. Told her yes, it's been that way for most of my life! She loves it because it gives her more control over her life. She realizes that she needs the oxygen, but maybe not as much as the doctors are saying she does. She checked it at the doctors and it was very close to thier readings. I told her since it's small she could check it a few more times. She loves it, it's small, appears to be well built, the numbers are large and the price can't be beat, not for something of decent quality. I really don't see her abusing it. I am also very glad I came here to check it out and read the reviews first, so I knew I was buying something of quality and it is performing as advertised and reviewed! (I am now out of the dog house for awhile, thanks to everybody!)

I started out looking for a Heart Rate Monitor (HRM) and ended up testing these 3 items. Over the course of a few days, during simultaneous tests (at rest & during light workouts), their readings were so indistinguishable from one another that I cannot honestly declare one better than the others. In that respect, all three are very good. All three use Finger Pulse technology, so no straps are needed. Here are some observations that I hope will help folks make an informed decision: 1- The Omron looked stylish from the picture on Amazon, but in reality, looked like an oversized, clumsy toy to me; I also did not like the digital display (the font style); Timex looks more graceful, and the display is better. 2- The Omron shows just the Heart Rate whereas the Timex shows not only the Heart Rate, but also the Relative Heart Rate (HR / Max. HR), and whether the HR is within the set Target HR Zone, over it, or under. That is nice. 3- Both watches have calories burnt feature, and stop watches; but Timex also has a Countdown Timer, and a second Time Zone (so one can set up clocks for 2 different parts of the world) 4- The night-light in the Timex also seems better to me, compared with the Omron 5- Omron uses two fingers for measuring HR, while Timex uses one. 6- Timex offers 2 sizes, midsize vs. fullsize; I recommend fullsize, because the display is bigger and much easier to read during any activity; seems more like normal to me, than the impression that "fullsize" conveys; and its cheaper than the midsize. I would have called them standard vs. small. 7- During setup, Omron does not incorporate gender, while Timex does; it's not that important but helps in setting up Target HR Zone. 8- I think that the Finger Pulse Oximeter SM-110 is good for the whole family; the user setup on the watches ties them to the wearer, while the Oximeter does not need any setup; it will dutifully do its job, and can be used for family fun and health; of course, it also shows the Oxygen Saturation level; and it comes with a carry case and neck / wrist cords. 9- FYI, the Activity mode on the Timex shows many more calories burnt than my Schwinn Exercise bike (almost 200 cal. difference on a 45 min workout); don't know if my bike is under-reporting, or the watch over-reporting. Overall, I think the Timex is a much better value for money than the Omron. Also, it goes without saying that these devices should be periodically cleaned to get accurate readings, as explained in their respective manuals. I'm keeping both the fullsize Timex & the Oximeter.

I ordered this for my husband, who needs to monitor his pulse and blood oxygen level. Normally, this unit retails for $199 and it was $25 on Amazon Prime. It works like a charm and is easy to read and use. It is important for him to have a reliable monitor. His blood pressure was dangerously high and his blood oxygen level very low and consequently, he spent several days in the hospital. It was his doctor's suggestion that he get a blood pressure cuff, but this seemed very old fashioned and cumbersome, plus it would not give him information about his oxygen level. This meter was the answer. It is extremely compact so it is unobtrusive and even comes with batteries. He can discretely monitor his levels and no one need be the wiser. This unit is far superior to anything sold at the drugstore. It was also much less expensive. I don't know why it was so inexpensive on Amazon but I love my hubby and am thankful we found an appliance that is reliable, compact, discrete and within our budget. If you need to monitor your pulse and oxygen level, I recommend this unit highly. He has found it very valuable and will use it often (as he has promised his doctor to do). This is an excellent piece of equipment and is well worth the price.

Lovely gadget great asset for work. Good clear reading loved by my nursing staff. A very good buy thank you.

Yes. I've become a slight hypochondriac since Covid, and I originally bought this pulse oximeter to form part of my Covid first aid kit. It works really well and is actually accurate, considering the low cost. I am pleased to say my blood oxygen saturation is high, though so is my pulse...hmm. lol

we are a care home and the nurse wanted this to monitor our residents well-being - has been great at signalling issues and we have been able to give feedback to the hospital or paramedics already

The product works well, though sometimes it's a little hit and miss with recognising finger placement for reading o2 saturation. The finger position on the device needs to be carefully positioned for it to read properly. It's something that just takes a little getting used to. I would not hesitate to recommend this product.

This item is great for putting in your handbag as it is compact, even when in it's little pouch. It can also be worn around the neck if you're in a situation where you're likely to need to get to it more easily. It's easy to use & easy to understand (the numbers are not too small to read). It's the perfect size for someone who's into first aid or needs to carry this round on a more regular basis. It also has a little loop on the pouch so it can be put on a keyring or a narrow belt. I would recommend this product to anyone. A 9yr old could use & understand it if necessary.
