- Bluetooth trending for physician review
- Accurate during motion (breathing effort)
- FDA Class II cleared
During an asthma attack, peripheral vasoconstriction and rapid breathing can throw off standard pulse oximeters. The Masimo MightySat's SET technology is built to stay accurate through motion, poor perfusion, and respiratory compromise, which are exactly the conditions an asthma attack creates. You can set your own …
Practical considerations for daily operation.
Designed to slot into a typical daily-use routine without friction.
Plan a short learning curve to get a feel for the device's prompts and ideal positioning.
Keep the unit clean and store it in a dry case to preserve accuracy long-term.
Best kept on a counter or shelf at home; not engineered for daily commuting.
App access unlocks history and trend tracking, but on-device readouts cover daily use.
During an asthma attack, peripheral vasoconstriction and rapid breathing can cause standard pulse oximeters to produce unreliable readings. The Masimo MightySat's SET technology is specifically designed to maintain accuracy during motion, poor perfusion, and respiratory compromise — the exact conditions present during an asthma attack. Customizable SpO₂ alarm (set your personal threshold) alerts you before dangerous desaturation occurs. Respiration rate measurement provides additional clinical data. FDA Class II cleared.
The Masimo MightySat Rx alongside our top picks in pulse oximeters.
During an asthma attack, peripheral vasoconstriction and rapid breathing can throw off standard pulse oximeters. The Masimo MightySat's SET technology is built to stay accurate through motion, poor perfusion, and respiratory compromise, which are exactly the conditions an asthma attack creates. You can set your own SpO₂ alarm threshold so it warns you before desaturation gets dangerous. It also measures respiration rate for extra clinical data. FDA Class II cleared.
