Question 1

Is there an API that could be utilized to capture the data via bluetooth in real time without using the provided app?

Accepted Answer

Use a Raspberry pi with BLE or add a USB, pair/connect it with gatttool, read bluetooth heart rate service, update the notify flag to true, write a shell script to continue receive data, either write to a file or write to a rrd DB to watch the realtime graphs. Totally doable, if you have knowledge and time spent on technology instead of FB, Twitter nonsense. No API needed.

Question 2

Manufacturer ‎Masimo please!  Why can't rechargeable batteries be used?

Accepted Answer

I do not represent the manufacturer, but the engineering answer is that a pair of non-rechargeable alkaline cells in series put out 3.0 volts when fresh, whereas a pair of rechargeable cells (whether NiCd or NiMH chemistry) only put out 2.4 volts for most of their useful life. For many types of electronics, 2.4 volts isn't enough to run them. For some devices, you might add another cell to the rechargeable battery pack to get up to the required voltage, but the finger-sized MightySat doesn't have any room to do that. That said, a pair of AAA alkaline batteries will run the MightySat for several hours of measurements. If you need continuous measurements for days on end, then you need a medical device that plugs into the wall, or has a large battery pack.

Question 3

Does this support multiple users?

Accepted Answer

I am a Physical Therapist Assistant and I use it everyday with all of my patients.  It gives me a readout that BlueTooth's to my cell phone. I can email the results to myself of my patient.  There are instructions to that effect in the user manual, lots of studies about the efficacy of the information which corresponds to other Masimo Finger Tip Pulse Oximeters (I have three) and it suggests that you use the fourth finger, but I have good results on any finger.  Very impressive technoology, and you can tap the screen on the cell phone if you want a quick reminder what the values tell you for example the Perfusion Index gives you the blood speed in centimeters per second.  Or the Plethysmographic Index gives you parameters of 5 and 40 for the ratio of dynamic over static blood flow, which tells you if you have "over-hyrdrated yourself or as is usually the case under hydrated, or dehydrated yourself either by not drinking enough fluid or exercising the fluids out of your body.  But "Water Intoxication" can also occur.  That is another advantage of this technology.

Question 4

What does "ability to trend and communicate measurements " really mean? Does it mean to store recording history, and for how long.? I

Accepted Answer

Yes. If you select one of the two Bluetooth compatible versions of MightySat, your measurements can be viewed on the smart phone (after downloading the Masimo Personal Health App) for up to 12 hours. The App also displays your measurements over time (trend screen). The data captured can also be emailed as .CVS file.
