A hyperbaric oxygen therapy (HBOT) facility stocks for two different populations at once. A minority of cases are urgent-indication referrals — decompression sickness, carbon monoxide poisoning, gas embolism — but the steady, day-to-day caseload at most outpatient HBOT centers is chronic, non-healing wounds referred for adjunctive treatment, diabetic foot ulcers most common among them, treated over a multi-week course of daily sessions. That mix drives a supply list unlike a general clinic’s: a dressing and wound-assessment stock deep enough to match what’s already being managed outside the chamber, patient-preparation supplies restricted to materials that are actually safe to bring into a pressurized, oxygen-enriched environment, and otologic supplies for the ear-barotrauma monitoring that is the single most common complication of treatment. This checklist covers what a hyperbaric facility needs to stock for that caseload and that environment. It does not cover chamber design, fire suppression, or the pressurization and depressurization safety protocol themselves — that is chamber-safety and life-safety survey territory, addressed on CASRAI’s NFPA 99 Health Care Facilities Code guide and NFPA 101 Life Safety Code guide. For the dressing and wound-supply overlap specifically, this page is a companion to CASRAI’s Wound Care Clinic Supply Checklist, which covers a specialty wound clinic’s full stocking list — many HBOT programs operate directly alongside, or effectively as, a wound-care clinic.
Where to source this: LAC (lac.us), CASRAI’s sister medical-supply business — a real, first-party sourcing option under the same operator as CASRAI, not a third-party affiliate — stocks the core categories an HBOT facility needs directly: browse LAC’s medical dressings category for the post-session wound-dressing stock covered below, and the first aid kits category for base emergency-response supplies in the treatment suite. Confirm sterile/non-sterile designation and case-pack sizing on the product page before ordering.
What Makes an HBOT Facility’s Supply List Different
Two things separate an HBOT facility’s stocking problem from a general clinic’s. First, the caseload: most outpatient hyperbaric programs run predominantly on wound-care referrals, with a smaller volume of true urgent-care indications layered on top, so the supply plan has to cover both a wound clinic’s dressing depth and a basic emergency-readiness baseline in the same building. Second, the chamber itself imposes a material constraint nothing else in a typical clinic does — a monoplace chamber is pressurized with 100% oxygen, and multiplace chambers deliver oxygen to patients breathing air at pressure, so anything that enters the chamber with a patient has to be compatible with an oxygen-enriched atmosphere. That constraint reaches into ordinary stocking decisions (what gown fabric, what skin product, what dressing goes in with the patient) even though the full fire-safety and chamber-design protocol behind it is out of scope here; see the NFPA 99 and NFPA 101 guides linked above for that. If you’re building general outpatient clinic infrastructure first rather than an HBOT-specific supply list, CASRAI’s clinic startup equipment checklist covers the exam-room and capital-equipment baseline this page builds on top of.
Wound-Care and Dressing Supply Overlap
Because the largest share of most HBOT patients are already under active wound-care management — diabetic foot ulcers, arterial ulcers, radiation-damaged tissue, compromised grafts and flaps — the facility’s dressing stock has to interoperate with whatever protocol the referring wound clinic already has the patient on, not replace it. That means keeping a broad-enough dressing formulary on hand to redress a wound immediately after a session in the same materials (or a documented, physician-approved equivalent) the patient arrived in, plus wound-measurement and photography supplies to track healing across a multi-week treatment course. A standard clinical practice at most HBOT programs is removing topical dressings and any petroleum-based or oil-based ointment before a patient enters the chamber and redressing afterward, since those products are not considered safe in an oxygen-enriched pressurized environment — which means the facility needs enough dressing and clean-application supply on hand to redo that step for every patient, every session, not just stock for periodic changes. For the full specialty wound-care stocking list this overlaps with, see CASRAI’s Wound Care Clinic Supply Checklist and the general wound care supply selection guide; for the closely related diabetic-foot-ulcer referral overlap, see the podiatry office supply checklist.
Chamber-Safe Patient Preparation Supplies
Every patient entering a chamber needs to be outfitted in materials the facility’s safety protocol has cleared for an oxygen-enriched environment — the specific compatibility rules and fire-risk rationale are chamber-safety and NFPA 99 Chapter 14 territory (see the guide linked above), but the facility still has to keep the compliant supplies in stock in the first place. In practice that generally means: 100% cotton patient gowns and linens rather than synthetic or wool fabrics, which can generate static charge; water-based skin and hair products rather than petroleum-, oil-, or alcohol-based ones for any patient who arrives wearing the wrong kind; cotton bouffant caps; and, where the facility’s protocol calls for monitoring leads inside the chamber, only the specific chamber-rated lead sets and water-based gel the medical director has approved — not general-purpose EKG stock pulled from the rest of the clinic. Keep a visible per-patient prep checklist at the chamber entry point so front-line staff aren’t relying on memory for what’s compliant.
Ear-Barotrauma Prevention and Otologic Supplies
Middle-ear barotrauma is the most common complication of hyperbaric treatment, since every session pressurizes and depressurizes the ear canal the same way air travel does, repeated daily over a multi-week course. Facilities generally stock: otoscopes for a pre-session ear check at intake and whenever a patient reports pain, decongestant nasal spray or oral decongestant per the medical director’s standing protocol, and ear-clearing training aids (nasal balloon devices, Valsalva/Toynbee instruction materials) for patients who need coaching on clearing technique before their first few sessions. Myringotomy kits and tube-placement supplies are physician-use items for patients who can’t clear despite coaching or premedication — stock per the medical director’s order set, not as a general front-line supply.
Emergency-Response Readiness
This is deliberately scoped narrower than it sounds: chamber fire suppression, rapid decompression procedure, and the emergency egress protocol for a patient mid-session are chamber-safety and life-safety code territory (NFPA 99 Chapter 14, linked above), not a stocking question this page answers. What the treatment suite still needs, the same as any outpatient medical facility, is basic emergency-response readiness for the space outside the chamber itself: a stocked first-aid kit at the treatment desk, an AED, oxygen delivery supplies for use outside the chamber (nasal cannula, non-rebreather masks), and a clear, posted protocol for who calls emergency services and from where. See the LAC sourcing note above for the base first-aid-kit category; case-pack sizing should scale to the facility’s daily patient volume, not a single generic kit for the whole building.
Chamber Turnover and Sanitation Supplies
Between-patient turnover in a multiplace chamber, or between-session turnover in a monoplace unit, needs its own supply line: chamber-compatible, non-flammable disinfectant wipes or solution rated for the chamber’s interior surfaces, acrylic-safe cleaning supplies for a monoplace chamber’s viewing dome (standard glass cleaners can craze acrylic over repeated use), and a laundering turnover stock of cotton gowns and linens large enough to cover the day’s full patient schedule without a mid-day gap. Facilities running a tight session schedule generally keep more turnover linen on hand than session count alone would suggest, since laundering lead time, not chamber availability, is usually the actual bottleneck.
Documentation and Monitoring Supplies
Beyond the chamber’s built-in monitoring, most programs stock: pulse oximetry for pre- and post-session checks, wound-measurement tools (disposable rulers, tracing film) and a camera or dedicated wound-photography setup to document healing across the treatment course, and paper or tablet-based treatment-log stock for the session count, pressure, and duration each payer typically requires as part of ongoing medical-necessity documentation. Facilities offering transcutaneous oxygen (TcPO2) testing to help justify continued treatment need the electrode and calibration-gas consumables that testing requires kept separately from general clinical supply, since it’s typically ordered less frequently but can’t be substituted with anything else on short notice.
Accreditation and Documentation Readiness
Many outpatient HBOT programs pursue accreditation through the Undersea and Hyperbaric Medical Society’s facility accreditation program, which reviews clinical protocols, staff credentialing, and equipment/supply readiness as part of the survey, alongside whatever hospital-based accreditation (TJC, DNV, or a state licensing survey) the parent facility already carries if it isn’t freestanding. Whichever accrediting body applies, the practical supply-side implication is the same: keep a documented par-level and reorder point for every category on this page, not just an informal sense of what’s usually on the shelf, since a survey will typically ask to see how stock levels are tracked and reordered, not just confirm the stock physically exists on the day of the visit.
Building Par Levels Around Session Volume
Unlike a general clinic where patient visits are one-off, an HBOT patient on a standard treatment course returns daily, five or six days a week, for anywhere from roughly 20 to 40-plus sessions depending on indication and response — which means per-patient consumables (dressing changes, gown turnover, ear-clearing aids) get consumed at a predictable multiple of the daily patient count, not a one-time-per-patient rate. When setting initial par levels: size dressing and prep-supply stock to daily chamber throughput times the average sessions-per-week per patient, not to new-patient count; size linen and gown turnover to the full day’s schedule plus laundering lead time, not to chamber capacity; and review otologic-supply consumption separately, since it clusters heavily in a patient’s first several sessions before clearing technique improves, then drops off — a flat per-session estimate will overstock steady long-term patients and understock a facility running a lot of new starts in a given month.
Vendor and Ordering Considerations Specific to HBOT
A handful of ordering realities are specific enough to this vertical to plan around rather than discover mid-shortage. Chamber-rated and oxygen-compatible products — disinfectants labeled safe for use in an oxygen-enriched environment, chamber-rated monitoring leads, cotton-only linen lines — are a smaller product category than general medical supply, sold by fewer vendors, and typically cost more per unit than the general-purpose equivalent; substituting a general-purpose product to save on a routine reorder is exactly the kind of shortcut that turns into a compliance gap at the next accreditation survey. Lead times on lower-volume specialty items (chamber-safe acrylic cleaner, otologic-specific supplies, calibration consumables for TcPO2 testing) also tend to run longer than general dressing stock, so those categories deserve a higher reorder-point buffer than their per-week consumption alone would suggest — running out mid-week on a fast-moving dressing is a minor scramble; running out of a specialty item with a two-week vendor lead time can mean turning away scheduled sessions.
Supply Storage Near the Treatment Area
Storage location matters more here than in a general clinic because staff are moving between the chamber and the supply point constantly through a packed daily schedule, and because some of what’s stocked (chamber-rated cleaning solution, in particular) has its own flammability and storage-compatibility considerations that overlap with, but aren’t identical to, the chamber’s own material-safety rules. Keep day-of-use consumables (prep gowns, dressing-change supplies, otologic aids) in a cart or shelf immediately adjacent to the treatment suite so a session isn’t held up by a supply-room trip, and keep bulk reserve stock and chamber-rated chemicals in a separate, ventilated storage area per the product’s own safety data sheet — not doubled up in the same small treatment-area cabinet where daily-use stock lives.
Staff Handoff and Supply Ownership
A treatment suite running back-to-back sessions all day tends to have several different staff members touching the same supply cart across a shift — whoever preps the next patient, whoever handles turnover after the last one, whoever restocks between sessions — and without a clear owner, restocking quietly slips to whoever happens to notice a shelf running low, which is exactly how a specialty item with a long vendor lead time runs out unnoticed. Assign explicit restock ownership (a named role, not “whoever’s free”) for at least the categories most likely to interrupt a session if they run out: chamber-safe patient-prep supplies, otologic aids, and the chamber-rated cleaning product used for turnover. A short end-of-day stock check against the par levels described above catches a shortfall while there’s still time to expedite an order before it becomes a scheduling problem.
Frequently Asked Questions
What’s the practical stocking difference between a monoplace and multiplace hyperbaric chamber?
A monoplace chamber holds one patient and is pressurized with 100% oxygen directly, so every fabric, dressing, and skin product that enters with the patient has to meet that chamber’s material-compatibility rules. A multiplace chamber is pressurized with air and patients breathe oxygen through a mask, hood, or head tent, which changes what needs to be oxygen-compatible — the delivery interface and its seals matter most — but doesn’t remove the general-materials caution for the shared chamber space itself.
Do HBOT patients need a special dressing removed before every session?
Most programs remove topical dressings and any petroleum- or oil-based product before a patient enters the chamber and redress afterward, since those aren’t considered chamber-safe. Exact protocol varies by facility and chamber type — follow the facility’s own medical director-approved list rather than a general assumption.
What’s the most common complication HBOT facilities need to be stocked to handle?
Middle-ear barotrauma, from the repeated pressurization and depressurization each session puts the ear canal through. Facilities generally stock decongestants, ear-clearing training aids, and otoscopes for pre-session checks; myringotomy supplies are a physician-order item for patients who can’t clear despite coaching.
Is chamber fire-safety equipment part of this checklist?
No — fire suppression, rapid decompression, and chamber emergency-egress protocol are chamber-safety and NFPA 99 Chapter 14 territory, covered on CASRAI’s NFPA 99 guide. This page covers the facility’s day-to-day clinical and wound-care supply stock, plus basic emergency-response readiness for the treatment suite outside the chamber itself.
Why can’t a general medical-supply cleaning product be substituted for a chamber-rated one?
General-purpose disinfectants and cleaners aren’t necessarily rated safe for use on or near chamber surfaces in an oxygen-enriched environment, and an acrylic viewing dome can craze or degrade under a standard glass cleaner over repeated use. The compatibility rule itself is chamber-safety territory (see the NFPA 99 guide), but the practical stocking implication is straightforward: keep the chamber-rated product on the reorder list as its own line item rather than assuming any general facility cleaner will do.
How does session volume change what a facility should keep in stock, compared to a general clinic?
A general clinic’s supply plan is mostly driven by new-patient volume. An HBOT facility’s is driven by session volume, because the same patient returns daily across a multi-week course and consumes per-session supplies (prep gowns, redressing materials, otologic aids) at every visit, not just at intake. Sizing par levels off new-patient counts alone will understock a facility with a full daily treatment schedule even if its new-patient volume looks modest.
For the broader lab and facility equipment context this checklist sits inside, see CASRAI’s lab equipment and instrumentation pillar. For the general clinic equipment baseline an HBOT program is typically built on top of, see the clinic startup equipment checklist; for the wound-care and diabetic-referral overlap this page complements, see the Wound Care Clinic Supply Checklist and podiatry office supply checklist. None of the above substitutes for the facility’s own medical director-approved protocol — treat this checklist as a stocking-planning reference, not a clinical or safety standard in itself.
