How do I check a medical supply store’s stock of oxygen and respiratory equipment?

Walk the stock with a list in hand and match it to the seller’s inventory records. Check each unit’s condition, service history and cleaning routine, and find out which items are owned, leased or held for clients. Ask how cylinders and concentrators are tracked, because missing or untraceable units are the usual surprise.

Ask for the full equipment list before the visit, then count what you see against it. Note the make and age of concentrators, portable units, cylinders and accessories, and look for any that are spare, damaged or waiting for repair. A shelf that looks full can hide a lot of units that are not ready to go out.

Next, ask about ownership. Some units may be out with clients, some on lease from a supplier, and some owned outright. Ask for the records that show where each item is and who is responsible for it. If cylinders are refilled by an outside supplier, ask for the agreement and how exchanges are tracked.

Finally, ask how equipment is serviced, cleaned and tested between uses, and who keeps those records. Look at them for gaps. Ask whether any stock is slow moving, outdated or no longer supported by its maker, since old stock can sit on the books but be hard to place. An equipment appraiser can help with condition. Ask as well how out-of-date or recalled units are pulled from service, and who decides when an old unit is retired instead of being repaired once more.

Key takeaways

  • Match the physical count to the seller’s equipment list unit by unit.
  • Separate owned, leased and client-held equipment in the records.
  • Ask for cleaning and service logs and look for gaps.
  • Ask how old or faulty units are pulled from use and recorded.
