Respiratory equipment is a deceptively technical category. The hardware sells once; the consumables sell forever; and a single misread flow rating turns into a wall of returns at the loading dock. Solution Medical Supply built this guide to demystify oxygen concentrators, CPAP and BiPAP machines, and nebulizers for clinic and home-health buyers — so you stock the right devices and the consumable lines that keep them running.
Oxygen Concentrators: Stationary vs. Portable
Stationary concentrators deliver higher continuous output for home-bound patients who need oxygen around the clock; portable concentrators trade output for mobility, freeing ambulatory patients to leave the house. Most respiratory programs carry both, because the two answer different prescriptions. Lead with the patient’s oxygen order, not the showroom photo, and the stationary-versus-portable choice makes itself.
Sizing Oxygen Output to the Prescription
The single most common procurement error in respiratory is mismatching delivery mode to the prescription. Continuous-flow output and pulse-dose delivery are not the same, and a patient prescribed continuous liter-flow will not be served by a pulse-dose portable unit. Read the flow rating against the order every time — this is where returns come from.
CPAP, APAP, and BiPAP — Knowing the Difference
CPAP delivers one fixed pressure; APAP auto-adjusts within a range; BiPAP splits inhale and exhale pressures for patients who cannot tolerate a single high pressure. Each maps to a different prescription and a different price point. Stock to the prescriptions your referral base actually writes, and train the buying team to read the therapy type off the order before substituting a model.
Nebulizers for Clinic and Home Use
Nebulizers split into tabletop compressor units for steady home and clinic use and compact mesh nebulizers for portability. The clinical output is similar; the durability, noise, and treatment time differ. Carry a reliable tabletop workhorse and a portable option, and keep the medication cups and tubing stocked alongside them.
Consumables: Masks, Cannulas, Tubing, and Filters
The recurring revenue in respiratory is the consumable line. Masks wear out, cannulas are replaced routinely, tubing and humidifier chambers cycle on schedule, and filters are a standing reorder. Build the consumable formulary around each device platform you carry so a machine sale automatically seeds a re-order relationship. This is the part new sellers leave on the table.
Maintenance, Duty Cycles, and Service Life
Concentrators have sieve beds and compressors with defined service lives; CPAP units have filters and humidifier maintenance; nebulizer compressors have duty cycles. Know the maintenance schedule for every platform you stock, set patient expectations accordingly, and keep the service parts that prevent a device from going dark mid-prescription.
Stocking Respiratory Equipment for a Program
Respiratory demand has seasonality — cold-and-flu season drives nebulizer and consumable spikes. Set par levels that absorb the surge, stock consumables deeper than hardware, and keep the fast-moving masks and filters where they never run dry. A respiratory line is a stocking discipline as much as an equipment list.
