Masimo Professional Health is a free iPhone app developed by Masimo in the category of Education & Reference, specifically targeting the field of Medicine. This app is designed to work in conjunction with the iSpO2 Rx pulse oximeter or MightySat Rx fingertip pulse oximeter, which are hardware modules that need to be purchased separately.

With the Masimo iSpO2 Rx or MightySat Rx, healthcare professionals can easily and non-invasively measure blood oxygen saturation and pulse rate. The app provides real-time measurement tracking, historical data trends, and the ability to share data via email. It also features Masimo's Signal Extraction Technology (SET), which ensures accurate pulse oximetry measurements even in challenging conditions such as motion and low perfusion. This technology reduces false alarms and increases the detection of true alarms.

In addition to measuring oxygen saturation and pulse rate, the MightySat Rx fingertip pulse oximeter also provides perfusion index (PI) and pleth variability index (PVI) measurements. The PI indicates arterial pulse signal strength, while the PVI measures the dynamic changes in PI during the respiratory cycle. The app also includes a respiration rate monitoring feature derived from the plethysmographic waveform.

Masimo, a leader in hospital pulse oximetry, has been dedicated to noninvasive patient monitoring for 25 years. The app is fully integrated with Apple Health, allowing users to easily manage and access their health data.
