Select Sensor Size

  1. Accurate During Challenging Conditions

    • Uses hospital-grade Masimo SET® pulse oximetry
    • Masimo SET® technology was shown in a study to be more accurate than 19 other pulse oximeters in healthy volunteers under motion and low perfusion conditions1
  2. Signal I.Q.® (SIQ)

    Provides an assessment of the confidence in the displayed SpO2 value

  3. Masimo iSpO2 Free App

    Graphically view your SpO2 and PR measurement history over time and share that data through email


1 Barker SJ. Anesth Analg. 2002 Oct;95(4):967-72. A total of 70 volunteers were tested with motorized hand motions. Each motion was studied during both room air breathing and hypoxemia. Pulse oximeters on the stationary hand were used to provide control measurements for comparison.

The iSpO2® has the ability to email up to 12 hours of measurement history and share data through email. Plus, it’s backed by a one-year limited warranty.

Device Compatibility:

12 reviews for iSpO2® Pulse Oximeter with Lightning Connector for iOS Device

  1. 5 out of 5

    Device works great with my Ipad. Purchased it to do a sleep study. The data for 9 hours is easy to load into Microsoft Excel and plot for the whole night. Found that back sleeping is bad, side sleeping much better.

    If you have any sort of sleep disorder (among other conditions), then you may want a pulse oximeter to help you check your O2 levels throughout the day or night. Although there are plenty of stand-alone devices, those that are accurate and can record O2 levels over time are fairly expensive.

    Enter the Masimo, and now you have an accurate pulse oximeter that can be plugged into your iPhone, and mobile software can be used to collect and display the data. This is definitely the trend for personal healthcare devices.

    I did have a few issues getting the software to run – crashed a few times, and hung my phone a few others. Still, I’d say it generally works fine, and should be reliable enough for most uses. It’s pretty basic stuff, but I’m sure there will be future releases adding features and capabilities without forcing me to go out and buy another unit every time.

    Definitely worth a look if you require a convenient way to record O2 levels.

    Nearly perfect. Best yet! This is my third pulse ox meter. First one that’s connected. The graphic beats have helped us identify a mild arythmia which I’d felt, but no one’s seen it. Now they can. I find the beat audio helpful since it tracks by tone the beats. Higher pitch for faster beats. Connected easily to my iPad. Haven’t tried the phone, but iPad is fine.
    I would agree with one reviewer that the “history” is not simple to see, but I honestly haven’t studied the directions. I’m very glad I upgraded to this device.

    I love my Massimo iSpO2! I am a paramedic and this sensor has outperformed the Nelcor sensor attached to my $20,000 cardiac monitor! I have used dozens of different varieties of Nelcor sensors and this one runs circles around them all. I have had my iSpO2 pick up on low perfusing Pts when nothing else would. The perfusion index gives me much more confidence in the veracity of the readings. The Apple app could use some more sophistication when it comes to displaying and exporting the history data. The sensor does use significant amounts of battery and you can’t charge it while using it. The cable is somewhat short at about 2 to 2.5 feet. My only regret is now that I have had the iSpO2 a month, Massimo has announced the MightySat.

    I am a nurse and was surprised to discover that this ispo2 pulse ox was identical (shape, design, brand with the exception of the connection point) to the pulse ox I use at my hospital. Correspondingly, I put the ispo2 pulse ox I purchased on my finger and the hospital pulse ox on the same finger opposite hand to test accuracy. Readings were virtually identical, with a variance of only 1% from one O2 sat to another. I was almost scared people would think I was stealing a hospital O2 sat when I put the one I purchased in my bag after testing it as it was virtually the same monitor. Of note I purchased the small O2 sat by accident, and am 130lbs. Interestingly enough the small O2 sat appears to be what my hospital is using too. I suppose they only order smalls as they are a Childrens hospital; however most of my kids on my floor are audulescents and exceed the weight limit for the small, some by many pounds. They have not provided the staff with an alternate O2 sat for larger kids. Never released there were two sizes until order my own. Thus, I am keeping the small as I have small fingers and am making the assumption if it is good enough for my hospital (a top ranked hospital) and my patients it is good for me :).app works well on iPhone 5s and iPad Air. Basic but good… Added pics of hospital monitor so you can see how it is the same with exception of adopter. Again mine is for children.

    Works Great!

    Top quality instrument. Software is excellent and integrates very well with the iPhone.

  9. 5 out of 5

    Purchased this for my wife prior to some surgeries to monitor status at home. She was having some heart-rate abnormalities prior to her procedures. Trusted Masimo as that is the brand our hospital uses. The Ipod app is easy to use and the ability to track and download your stats is handy. The report that is generated in one-second intervals, so can be a bit lengthy, but VERY informative to track changes. We could determine exactly when she climbed the stairs, woke up from her sleep, etc. As disclosed by Masimo, this should NOT be presumed to be a medical-grade device, although it DOES work on the same principals as the hospital units, so I trust it…

  10. I love this highly portable pulse oximeter which is easy to hide away and carry everywhere AND has hospital grade accuracy. The soft carrying case is small enough to fit in a pocket. The iPhone app has a nice scrolling chart that makes it feel like fancy expensive medical equipment. I also have the MightySat (Bluetooth + Pleth Variability Index + Respiration Rate) which measures extra parameters. The biggest practical difference is that you can use the MightySat longer continuously without having to depend on the iPhone battery.

    So far my readings have been very consistent. Masimo pioneered the signal detection algorithms for pulse oximetry used in hospitals around the world. The iSpO2 uses same professional level technology which remains far ahead of the competition. Masimo is a US medical device company based in Irvine, California.

  11. displays well in iPad, O2 sat, pulse tracing all useful.

  12. I am a registered nurse and have used this in home-health care. It is a very solid, accurate, dependable, professional and convenient piece of equipment. I love using it out in the field. It picks up readings quickly, responds and reads where other little pulse/oximeters fail, which is a real and frequent problem when a good number of your subjects are elderly and others with compromised circulation.

    The waveform readings, perfusion index readings and ability to record data and transfer to my Mac make this device a substantial cut above the rest. It looks and feels like a professional piece of equipment because it is, and this inspires confidence with patients who recognize the sensor as being hospital-quality as opposed to something they could pick up at the pharmacy or Wal-Mart.
