Cómo hemos elaborado este informe
Roster covers 12 pulse oximeters spanning three tiers a 2026 buyer actually compares: clinical-grade Rx fingertip (Masimo MightySat Rx), professional spot-check fingertips (Nonin Onyx Vantage 9590, Nonin GO2 9570), consumer/aviation/sports fingertips (Zacurate Pro Series 500DL, Contec CMS50D, Innovo Deluxe iP900AP, Santamedical Generation 2 SM-165), connected/app fingertips (iHealth Air PO3M, Beurer PO60, Wellue FS20F), and continuous overnight-wear designs (Wellue O2Ring, Wellue Checkme O2 Max). Primary sources were official manufacturer spec sheets and Instructions-for-Use PDFs (masimo.com/nonin.com official brochures, Nonin Onyx Vantage 9590 and GO2 9570 IFU/spec-sheet PDFs), official brand storefronts (getwellue.com, shop-beurer.com, zacurate.com, innovo-medical.com, santamedical.com), and manufacturer/OEM pages (contecmedsystems.com, ihealthlabs.com/ihealthlabs.eu), cross-checked against authorized resellers (CardiacDirect, TurnerMedical, Win-Health, Hart Medical, MedicalMega) where the manufacturer page itself did not publish a spot price. Several official storefronts (getwellue.com, shop-beurer.com, zacurate.com, innovo-medical.com, santamedical.com) actively rate-limited automated fetches; those pages were retrieved via a read-only text-rendering proxy (r.jina.ai) mirroring the same live HTML, not through any authentication bypass. priceUsd is each product's current US starting price on its own official store where fetched (Beurer PO60 $29.99 and Zacurate 500DL $19.99 confirmed directly on the brand's own US site; several early aggregator snippets quoted stale/incorrect PO60 figures around $97-100 that the live shop-beurer.com page contradicts and which were discarded); where no official US storefront price could be retrieved, an authorized reseller's listed price is used and flagged in priceNote. continuous_monitoring is scored true only for designs the manufacturer explicitly markets for unattended overnight/extended wear (O2Ring, Checkme O2 Max); ordinary fingertip clips are spot-check devices even when Bluetooth-connected to a trend app, and Innovo's own product page and Wellue's own FS20F manual explicitly warn against extended/overnight use on one finger. Nonin GO2 9570 is confirmed discontinued (superseded by the Onyx Vantage 9590) but retained because it remains commonly stocked/compared secondhand and its spec sheet is Nonin's own PDF. Wellue FS20F is confirmed no longer listed for direct sale on Wellue's current US site (redirects/404s on old product URLs; the brand's own page states the model 'is currently only sold in the EU') even though US Amazon/Walmart third-party listings persist — priceUsd is left null rather than guessed from stale reseller caches. Adversarial corrections made this pass: Contec CMS50D SpO2 accuracy is officially ±2% over 70-100% (an initial aggregator snippet mis-stated ±4%, which is actually the device's separate low-signal/weak-perfusion figure); Beurer PO60 pulse-rate range corrected to the officially documented 30-250 bpm (a generic aggregator snippet had quoted 20-250 bpm); several SpO2/pulse-rate range and accuracy fields for Innovo iP900AP, Wellue FS20F (accuracy), and Santamedical Gen2 (range/accuracy) could not be verified on any fetched manufacturer or reseller page and are left null rather than assumed from comparable sibling models. accessedAt 2026-08-01 for all products.
