Source: cardiacdirect.com (verified 2026-08-01) · corroborated by henrotech.be. Masimo's own MightySat Rx brochure/spec sheet (fetched directly, P/N 9709/9809/9909 model table) confirms: SpO2 display 0-100%, PR 25-240 bpm, ARMS accuracy 70-100% SpO2 (±2% no-motion/low-perfusion, ±3% motion) and PR (±3 bpm no-motion/low-perfusion, ±5 bpm motion), Perfusion Index (0.02-20%) and Pleth Variability Index (0-100%, PVI on the 9909 only), a rotating 3.3 cm color display with pleth waveform, IP23, and battery life 'Approximately 1800 spot checks' footnoted as based on 15 hours of operation at 30-second spot checks. The 9809 configuration adds Bluetooth LE and the Masimo Professional Health app but not PVI. CardiacDirect's live product page lists $549.00 for this exact device; a second reseller (tactical-medicine.com) independently corroborates $549 standard / $649 with the PVI/RRp option. continuous_monitoring is set false because this is an Rx spot-check clinical device (no onboard trend memory; live data only while connected to the companion app), not a device marketed for unattended overnight wear like the O2Ring or Checkme O2 Max in this same dataset. No release year is stated on either fetched source; the brochure itself carries a 2015 copyright but that is a document date, not a confirmed launch year, so releaseDate is left null.
