Two terms, side by side

Pick any two terms to see definitions, context, pitfalls, and sources in parallel.

Market Segments

Sleep & Respiratory Devices

In one line

Devices for diagnosis and treatment of sleep-disordered breathing and chronic respiratory disease — CPAP, BiPAP, ventilators, and home sleep tests.

Definition

The sleep & respiratory segment covers home sleep test (HST) devices, polysomnography systems, CPAP and BiPAP/auto-titrating PAP, adaptive servo-ventilation, home and ICU ventilators, and oxygen concentrators. The June 2021 Philips Respironics recall of millions of CPAP/BiPAP devices over PE-PUR foam degradation is the largest medical-device recall in MedTech history and reshaped the segment's competitive structure.

Why it matters

DME reimbursement (HCPCS E0601 for CPAP) and supplier compliance (adherence-monitoring requirements) drive product design. Adherence monitoring data is now a routine payer requirement.

Common pitfalls

•Sourcing sound-abatement foams without long-term off-gassing characterization (the Philips lesson).
•Treating adherence data telemetry as optional — payers require it.

Why compare MedTech terms side by side?

MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.

Common comparison patterns

Regulatory pathway choice - 510(k) vs PMA, 510(k) vs De Novo, Abbreviated vs Special 510(k).
Quality systems - QSR vs ISO 13485, QMSR vs QSR.
Software classification - SaMD vs SiMD, Locked vs adaptive AI.
EU frameworks - MDR vs IVDR, CE Mark vs UKCA.
Cybersecurity artifacts - SPDX vs CycloneDX SBOM, CVE vs CVSS.
Post-market actions - Recall vs field action, Removal vs correction.
