How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The market size was built upward from device unit shipments across reservoir cannulas, electromechanical pulsing units and transtracheal catheter kits, combined with realized average selling prices by channel: institutional tender pricing, retail and durable medical equipment dealer pricing, and online direct pricing. Patient counts drawn from long-term oxygen therapy prescription volume anchored the home care estimate specifically. This bottom-up build was then checked against disclosed segment revenue from companies with reported respiratory or home healthcare divisions, including Air Liquide's healthcare segment filings and Invacare's respiratory products disclosures. Where the two diverged, the unit-price or channel-mix assumption feeding the bottom-up build was revisited and corrected, since the disclosed revenue serves as a check on the build rather than a second estimate averaged into it.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary outreach targets commercial and product management leads at device manufacturers, procurement managers at durable medical equipment dealers and home healthcare providers, respiratory therapists and pulmonologists who prescribe long-term oxygen therapy accessories, and regulatory affairs contacts tracking device clearance pathways. Sampling weights toward the United States and Western Europe, where reimbursement structures and prescribing volumes are best documented, with additional coverage in Japan and China to capture the fastest-growing demand base in Asia Pacific. Distributor and channel partner interviews supplement manufacturer contacts to validate how institutional, retail and online pricing actually diverges from list pricing in practice.
Desk research draws on the FDA's 510(k) clearance database, where oxygen conserving devices are catalogued as Class II respiratory accessories, and on CMS HCPCS billing codes covering home oxygen equipment and accessories, which provide a proxy for reimbursed unit volume in the United States. International trade data under HS code 9019.20 for breathing appliances supplements shipment estimates outside the United States. Industry association benchmarks published by the American Association for Homecare inform channel mix and dealer pricing assumptions, and company filings from publicly listed respiratory and industrial gas suppliers anchor the top-down revenue check.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from continued growth in diagnosed chronic respiratory disease prevalence, the ongoing shift of long-term oxygen therapy from institutional to home settings, and the gradual replacement of continuous-flow-only setups with pulse-dose conserving technology as device costs decline. Pricing is assumed to hold roughly flat in real terms in institutional channels and decline modestly in retail and online channels as competition broadens. The forecast normalizes for the demand pulled into 2020 and 2021 by pandemic-driven respiratory care capacity expansion, treating that period as an atypical peak, not a new baseline. For the forecast to hold, home care reimbursement policy needs to remain at least as supportive as it is today.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Back-testing compared the 2020-2024 historical build against recorded shipment growth reported in earlier industry editions of this category, confirming the same direction of travel even where the base levels differed. Segment share shifts, particularly the move toward pulse-dose delivery and home care settings, were reviewed against durable medical equipment dealer feedback on order composition. Sensitivities were tested on the pace of the institutional-to-home care shift and on how quickly pulse-dose devices displace continuous-flow-compatible setups, since both assumptions move the segment mix meaningfully without changing the total market size materially.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
Confidence is firmest in the home care and pulse-dose delivery estimates, where reimbursement coding and dealer channel data give a clear, checkable base. Confidence is thinner in the transtracheal catheter and institutional sales estimates, where reporting is sparse and volumes are inferred from a smaller set of proxies. The overall estimate sits well above the level implied by carrying this market's own 2022 edition forward at its stated growth rate, a gap addressed in the narrative. A future edition with better disclosure from privately held device makers could still move the total materially in either direction.
