Masimo MightySat Fingertip Pulse Oximeter with Bluetooth, Monitor Blood Oxygen Saturation and Breath per Minute, OLED Screen, Touchpad, Long Battery Life

Very accurate oximeter, not nearly as much artifact with movement etc. picks up quickly.

I have lung cancer and need oxygen on occasion. I have bought so many oximeters to try and monitor, but when put up against the ones at the doctor's office they were always off by quite a bit. Also old ones would take FOREVER to figure out my oxygen level. Not something you want to wait on when your struggling to breathe. Between the fast response, and the app to track and explain other values this is a great investment to track my levels. Plus when double checked at the doctor's office, Massimo is correct everytime. I also love the continuous monitoring aspect. I would highly recommend, but the cost is the only downside. I understand quality cost money, but health equipment like this is hard to find, at least ones that actually work.

I used this with my iPad app (free) to show a full night of data when there was a question whether I had Sleep Apnea. It showed both the averages and the peaks and valleys. The app has a graphic representation in a variable time scale. For me it showed my oxygen level dropped into the 75% level multiple times a night. This is not good. After a full sleep study I did get a CPAP machine and measured again. It did keep oxygen above 90% all night.When my wife wondered about her sleep pattern, she was able to see that her oxygen was sufficient all night long. The specifically say it is not for diagnosing Sleep Apnea. I can only say this device with the app certainly showed the impact on Oxygen levels and heart rate that was very helpful. It was more convincing to me that the actual sleep study because the sleep study environment did not simulate my personal experience. Using this device in my own bed, not hooked to wires, and not being woken up multiple times (as I experienced in the sleep study) was a better representation of my reality. I would recommend to a friend or buy again given the same situation.HINT: the brightness of the display is variable. When moving the brightness setting from high to low, the battery life extended significantly.

really good quality and great sensor...but too pricey...similar results to oxygen sensors costing 20$- $30

This works great for o2 levels and heart rate. one of the better ones I have bought. I was having issues with my o2 dropping and it work well to identify my issue.

The Masimo Mighty Sat pulse oximeter came with the batteries, a lanyard to wear around the neck and a soft pouch. I purchased it because I read that it was an accurate pulse oximeter during movement and low blood flow due to their Signal Extraction Technology. I still need to try it when taking a walk outside, but I tested it while using an exercise bike and the SpO2, Pulse and Pi worked, but the RRp and PVi did not pick up data until I stopped the exercise. I am primarily interested in the SpO2, and that has been fine so far.

I have central hypo-ventillation syndrome (ondine's curse) and bought this because I wanted something extremely accurate and medical grade. I already have a Contech CMS 50F and it is very good, but I didn't feel comfortable wearing it at work. I was also concerned the Contech had some movement artifact and that's why I needed something more accurate as my condition is extremely rare and the medical community wasn't taking me seriously. I wore my contech during my in-lab sleep study in Feb. While awake facebooking, the contech had me desatting to 87% and the lab had 85%. While asleep, the contech had me desatting to 75% and the lab recorded 74%. So the Contech is accurate to 1% - 2%. So I was able to have the sleep lab had to amend their report to confirm central apneas and desatting while awake. While at work on 26 April, wearing both the Massimo and the Contech, and working on the computer, I was desatting and fainting. The Contech recorded 85% and the Masimo was only reaching down to 92%-93%. I know you have to go below 88% to faint, so that's how I know the Masimo is inaccurate and the contech is providing numbers within range. I found the Masimo runs about 3% too high with little ups and downs. When I experience central apneas whether asleep or awake, my O2 sat goes up and down like a yo-yo and varies by 10%-12% in about 1 min cycles, also confirmed by the lab. The masimo levels would only vary by 2%-3%, yet it would show my breathing rate vary from 5 to 25 breaths per minute. As you can see in the attached photos, my breathing rate in the white graph varies widely, yet the graph of my O2 saturation hardly varies. Also, the data will not export after multiple tries. So the reporting capability doesn't work as advertised either.

After a long period of feeling exhausted all the time, I began to suspect that I was suffering from sleep apnea. This pulse oximeter is not cheap, but it is highly accurate and uses the same advanced technology as hospital-grade monitoring systems. After recording my night-time hypoxia and printing out the data for my doctor, he agreed that I needed a full sleep study. The study confirmed severe sleep apnea, and resulted in effective treatment for my condition. It also gave me peace of mind that the treatment was in fact effective in eliminating my night-time hypoxia. This device is not cheap, but it is worth every penny if you need to monitor your blood oxygen levels.
