Product Description

Size: Large

From the leaders in pulse oximetry, the iSpO2 Pulse Oximeter allows you to noninvasively track and trend blood oxygenation (SpO2), pulse rate (PR), and perfusion index (PI) - even during movement and low blood flow to the finger. With the free Masimo iSpO2 application, you can graphically view your SpO2 and PR measurement history over time and share that data through email. The iSpO2 features the same Masimo SET technology found in hospitals worldwide. The iSpO2 will be useful to anyone interested in measuring blood oxygen and pulse rate, such as hikers and climbers, as well as pilots and passengers. Not intended for medical use. SIZING: For sizing, we recommend the Large size for people over 66 pounds. The Small size is recommended for those under 110 pounds. If you are between 66 and 110 pounds, we recommend the Small size if you have slender fingers.

Manual says compatible with iPhone 5, 5s and mini iPad.

The unit NEVER requires me to reset my Iphone (turn it on and off to get it to work, which is a problem with the iChoice sometimes).
Han Solo
While expensive, this pulse oximeter is without doubt the best one available for the consumer market.

While expensive, this pulse oximeter is without doubt the best one available for the consumer market. Masimo uses impressive digital signal processing combined with proprietary LED technology. If you need a serious pulse oximeter, this is the one to get. I say this as someone who does extensive research using pulse oximeters. Note: I receive no funds or support from them and bought my iSpO2 retail from Amazon.

I have extensively evaluated the iSpO2 since purchasing one at CES in Las Vegas. I have found the unit to extremely accurate under normal conditions at rest with the finger probe on a stationary hand. I have compared my iSpO2 with units from my various surgery centers including Welch Allen and Masimo and found close correlation. I found that the surgical units respond slightly quicker to decreased pO2 associated with breath holding but overall my IspO2 was very close. The only downfall has been on my stair master on the highest level. The movement associated with the stair climbing action confuses the pO2 sensor. Despite the movement, the heart rate remains accurate and correlates well with my Polar strap. Overall I have found the quality of the iSpO2 to be excellent and the data extremely useful. I continue to use and evaluate the iSpO2 frequently. As a surgeon and avid fitness enthusiast I have really enjoyed the iSpO2. I have found the iSpO2 to be very well constructed, and accurate. As an aside, I as a surgeon rarely look at the brands of the anesthesia equipment in the OR. When I returned from Las Vegas, I asked my anesthesiologists about Masimo and learned that company is the industry leader with fantastic technology. This product is as I would expect from such a company.

This is a fine, if expensive, device. I use it with my iPhone 4 and the battery does not last overnight. The problem, essentially, is that it samples every second and this is too much for an iPhone 4 battery. I contacted Massimo and asked if an option existed to change the sampling rate to three, four, or five seconds. Cutting the sampling rate would solve two problems, battery life, and the massive CSV file generated from an overnight use. Apparently they're working on that, but there is no timetable. In order to use this massive file (about 25,000 lines for a full night) the first thing I have to do, after importing it into Excel, is delete two thirds or more of the data. Being able to change the sampling rate to every three or four seconds would eliminate all of this bother.
My interim battery life solution was to buy a 30 pin extender that also allows plugging in a mini USB connector from the side of the extender for charging the battery while using the 30 pin connector for the oximeter. This is a little bit clumsy but workable. Masimo literature says not to connect any charger while using the oximeter, but, according to technical support, this is only because of legal concern that somehow a user might get an electrical shock from a defective iPhone power supply sending 120v back into the iPhone and then out to the oximeter, where somehow the user might get shocked. Go figure! According to technical support, there is no risk of damage to the oximeter if a charger is connected to the iPhone while using the oximeter.
Sensitivity and repeatability are excellent, and I assume that accuracy is equivalent. On nights that I have used my CPAP, readings are consistently about 2% higher than on nights when I use my oral appliance, And this 2% difference correlates with how I feel in the morning. Now, the big question is, does this difference correlate to long-term differences in overall health.

I am a physician, but NOT a pulmonologist and my interest in the device was for Sleep Apnea monitoring overnight not exercise testing. I have also tried the iChoice Pulse Oximeter which is about $50 cheaper. Based on my limited experience in the hospital setting & with these other consumer units I would say that the basic finger construction of detecting your pulse & O2 sat are not dramatically different going from the cheaper to the more expensive price range. I sincerely doubt that the thing would get stable readings if you use it while exercising, but at rest its probably as good as any heart belt. I think that is true for any product that measures pulse and O2 sat in this manner (they just don't stay on the finger that well & while everyone uses the finger its a peripheral body part about as far away from the heart as possible). If you attempt to use this product with the idea that during exercise you might see a drop in your O2 sat, I think you might be sorely disappointed. Anyone in half decent shape will find it almost impossible to hold your breath or exercise so hard that you can actually see a meaningful drop (below 90%) in your O2 sat. I'm not sure how meaningful the numbers are between 92-99% as you will quickly find when leaving the unit on for a long time the readings will bounce around all of these numbers without obvious biological change on your part.

Here are the positives. The unit has a longer cord than the iChoice (great for moving around and keeping the phone further away), the construction appears to be sturdier, and the one cable design (as opposed to iChoice 2 pieces fit together) makes for a more stable device. The software measures PI (which is an index of how good the reading is) and shows the wave form (which probably to most people means very little).
