MightySat Fingertip Pulse Oximeter with Bluetooth LE, RRp, & PVi

$499 $299
Pulse oximeters measure light absorption in the finger to noninvasively monitor oxygen saturation and pulse rate. Fingertip pulse oximeters are being increasingly used for general wellness and health applications including sports, fitness, and relaxation management. Providing the following parameters:
  • SpO2 (Oxygen Saturation)
  • PR (Pulse Rate)
  • Pi (Perfusion Index)
  • RRp (Respiration Rate)
  • PVi® (Pleth Variability Index)

Performance Features

The Masimo MightySat™ quantifies key physiologic variables – in the morning, before or after exercise, at bedtime, or anytime you want to know if you are at your best.

This product comes with Bluetooth wireless interface to the free downloadable Masimo Personal Health app and Apple HealthKit via your smart device.

Masimo is the leading brand of hospital pulse oximeters¹ because they provide accurate measurements when other pulse oximeters fail by using a revolutionary, patented invention called Signal Extraction Technology® (SET®). Masimo SET® uses five parallel signal processing engines that measure through challenging conditions, including movement and low blood flow. With MightySat™, the same high-performing Masimo SET® technology is now available for general wellness and health applications.

Product Features:

  • Uses hospital-grade Masimo SET® pulse oximetry which is technology that was shown in a study to be more accurate than 19 other pulse oximeters in healthy volunteers under motion and low perfusion conditions2
  • Provides additional parameters not available on other pulse oximeters such as Perfusion Index (Pi), Respiration Rate (RRp), and Pleth Variability Index (PVi)
  • High-resolution display with rotating and adjustable color screen for clear display of all measurements
  • Extremely easy to use
  • Durable, lightweight design made from high-quality materials and backed by a two-year warranty

7 reviews for MightySat Fingertip Pulse Oximeter with Bluetooth LE, RRp, & PVi

  1. 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.

  5. I bought this for my elderly mom while she’s recovering from knee replacement surgery. She LOVES IT and said that it makes her feel more secure to carry this around in her belt pack. This gives her an idea of the “patterns” of 3 of the important vital signs (pulse, oxygen, respiration rate) while she’s resting and during exercise. Then she knows if something is out-of-whack even if she otherwise feels fine.

    The readings show up a few seconds after clamping it onto the finger and are very consistent. The display shows a cute little bar that jumps with each pulse. The iPhone app is quick & easy to connect with Bluetooth and has a beautiful moving graph that tracks history like a fancy medical monitor. I was able to show her how to use this without even reading any of the manual. A quick tap on the menu button flips the screen 90 degrees (one of four orientations).

    There is only one product improvement I would suggest if the manufacturer is reading this.. I’d like to be able to use Energizer Ultimate Lithium AAA batteries rather than regular alkaline because they last much longer (according to the manual it has to be regular alkaline).

    I only trust Masimo pulse oximeters for accuracy; the other copycats are inaccurate junk. At first I wasn’t sure if I should spend so much on a small gadget, but looking back at the decision, I am very happy I made the purchase. This is one of my favorite products of the year. Everyone in our family wants to “borrow” it from my mom because we are all curious of our fitness parameters.

  6. Forget the sat and heart rate readings. This thing gives you the PVI–plenth variability index–and indicator of the volume status of your patients. Masimo is selling a larger sized unit–which does the same thing–for about $5000. I don’t get why they would undercut themselves with a smaller unit for 1:10 the price. This unit has correlated well with the $5000 unit on 2 of the 3 patients I tested it on.
    Keep in mind PVI monitoring is about 80% sensitive and 80% specific for diagnosing low intravascular volumes in adult patients being positive pressure ventilated at 8+cc per kg at PVI readings <8 (adequet intravascular volume) and >13 (low intravascular volume).
    Only drawbacks are mediocre sensitivity for picking up pulse and eats through batteries.

  7. Great Product so far!! Great customer service too…
