The single most common procurement mistake in respiratory equipment is treating continuous-flow and pulse-dose concentrators as interchangeable. They are not, and the confusion shows up as a stack of returns at the loading dock from patients whose prescriptions the device could never meet.
Continuous-flow concentrators deliver a steady, prescribed liter-flow of oxygen regardless of breathing pattern — what most home-bound, higher-need patients are prescribed. Pulse-dose units deliver a measured bolus of oxygen on inhalation, which conserves the supply and enables small portable designs, but only suits patients whose prescription explicitly allows pulse delivery.
The practical rule is to read the oxygen order before matching a device. A patient prescribed continuous liter-flow will be under-oxygenated by a pulse-dose portable, full stop. A patient cleared for pulse-dose delivery gains mobility and freedom from a portable unit that a stationary concentrator can’t offer. The prescription, not the form factor, decides.
Our respiratory care equipment guide covers how to read flow ratings across the whole respiratory line, but this one distinction prevents more returns than any other. Train the buying team to match delivery mode to the order every time.
Lead with the prescription, match the delivery mode, and the returns at your dock largely disappear.
