What VirtuOx does

VirtuOx, Inc. is a US-based healthcare information technology company founded in 2005 and headquartered in Coral Springs, Florida, that provides vertically integrated home-based diagnostic testing and patient monitoring services. The company operates a proprietary HIPAA-compliant platform that ingests biometric data from a portfolio of FDA-cleared medical devices—including the NightOwl Mini disposable HSAT, the VPOD family of oximeters (Ultra, Dream, Handheld Pro, Capox, Vital Pro), the RhythmStar mobile cardiac telemetry monitor, and the Sleep Profiler PSG2—and uses AI-powered algorithms to convert that data into clinical reports for physician review. VirtuOx is accredited by The Joint Commission as an Ambulatory Care Sleep Diagnostic Center and certified by Medicare as an Independent Diagnostic Testing Facility (IDTF), enabling it to bill CMS and commercial payors under CPT codes G0400, G0399, and G0398. The company performs over 40,000 new diagnostic tests per month and has cumulatively served more than 6 million patients, 250,000+ referring physicians, and 4,000+ DME (Durable Medical Equipment) partners since founding.

VirtuOx serves three primary customer segments: individual consumers seeking convenient at-home sleep, cardiac, insomnia, and hypoxemia testing; healthcare professionals (physicians, sleep specialists, cardiologists, pulmonologists) who order and interpret diagnostic tests; and DME providers requiring overnight oximetry to qualify patients for home oxygen therapy under CMS requirements. The company monetizes through insurance- and Medicare-reimbursed diagnostic testing services, proprietary device sales to healthcare providers and DME partners, and the Sleepifi SaaS platform, which bundles HSAT software, devices, and logistics for physician practices and sleep labs on a subscription basis.

In May 2025, ResMed (NYSE: RMD) acquired VirtuOx to integrate its virtual home-based diagnostic testing platform into ResMed's broader sleep and respiratory care ecosystem. VirtuOx continues to operate as a fully owned subsidiary under its existing brand, retaining its leadership team. The acquisition was described by ResMed as not material to its financial results, implying VirtuOx sits in the sub-$100M revenue range.

Direct peers

• Compumedics: Compumedics is a global manufacturer of PSG, HSAT, and EEG diagnostic systems. Its Somté, Safiro, and other products compete with VirtuOx's polysomnography and home sleep testing device lines for sleep lab customers.
• Lofta: Lofta is a direct-to-consumer home sleep apnea testing and CPAP provider. It overlaps with VirtuOx's consumer-facing HSAT scheduling, telemedicine workflow, and sleep apnea diagnostic service line.
• ApneaMed (Watermark Medical): ApneaMed is an independent diagnostic testing facility specializing in home sleep apnea testing, very similar in business model to VirtuOx. It competes for the same DME partner referrals and physician prescription volume.
• Cadwell Industries: Cadwell manufactures PSG and EEG/neurodiagnostic equipment used by sleep centers and neurologists. Its Easy III PSG and related hardware overlap with VirtuOx's Sleep Profiler PSG2 unattended study offering.
• CleveMed: CleveMed manufactures SleepView and other home sleep apnea testing devices used by sleep labs and IDTFs. It competes directly with VirtuOx's NightOwl Mini, Alice NightOne, and Sleep Profiler HSAT/PSG portfolio in the home-based diagnostic channel.
