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.
