The concentrator can be humming beside the bed and the home plan can still be unfinished.

You need to know who owns the equipment, who maintains it, what your family must do, and what happens when it stops working. Do this while the hospital team and equipment supplier are still within reach.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Day 0, still in the bed: identify the owner

Ask the discharge planner to show you the oxygen order. Write down the prescribed equipment, the flow setting, when your parent is supposed to use it, and the name of the clinician who can answer questions about the order. Do not rely on a verbal summary.

Then ask whether each item is rented, purchased, or supplied under a different arrangement. The answer controls who handles repairs. Medicare says a supplier must maintain and repair rented durable medical equipment and keep it in good working order. An owner may have to find a supplier willing to service purchased equipment. Oxygen rental payments generally include necessary supplies, servicing, and maintenance. (Medicare, Oxygen Equipment and Accessories; Medicare, Coverage of Durable Medical Equipment and Other Devices.)

Write down the supplier's legal name, regular telephone number, after-hours number, and the address of the location responsible for your parent. Do not leave with only the driver's number.

Federal supplier standards require a Medicare supplier to maintain and replace rented Medicare-covered equipment directly or through a service contract. The supplier must also answer questions and complaints. (Electronic Code of Federal Regulations, 42 CFR 424.57.) CMS quality standards call for instructions about setup, routine use, troubleshooting, cleaning, infection control, and maintenance. They also call for regular and after-hours repair contacts and an emergency plan. (CMS, DMEPOS Quality Standards.)

Ask the supplier representative five questions:

Who takes the first call if the concentrator alarms or stops? What can we check ourselves? What must we leave untouched? How quickly will you provide repair or replacement equipment? What oxygen source should be used while we wait?

Put the answers in writing. If the supplier gives you a booklet, mark the pages for alarms, cleaning, backup equipment, and after-hours service.

Before the car pulls in: watch one complete setup

The person covering the first night should see the actual equipment operate. A general explanation in the hallway is not enough.

Ask the supplier or trained hospital staff member to demonstrate turning the unit on, reading its indicators, connecting the tubing, checking for a kink, and switching to the backup source. Have the family caregiver repeat the steps while the trainer watches.

Ask what every light, sound, and display means. Write the meaning beside a photo of the control panel. Do not change the prescribed flow setting during this practice. MedlinePlus advises oxygen users not to change the flow without direction from the health care provider. (MedlinePlus, Oxygen Safety.)

Look at the backup supply. Record what it is, where it will be stored, how to tell how much remains, and who replaces or refills it. Ask the supplier to state how long that specific backup is expected to last at the prescribed setting. Do not calculate this from a generic chart.

If no backup is being delivered, ask the supplier and discharge planner to explain the failure plan before your parent leaves. Missouri DHSS tells oxygen users to collect information about their oxygen needs and arrange alternate supplies before an emergency. (Missouri Department of Health and Senior Services, Preparedness Information for Oxygen Users.)

Day 1, the car pulls in: match the delivery to the handoff

At home, compare the delivered equipment with the written order and delivery ticket. Check the name or description of each item. Record the concentrator make, model, and serial number. CMS quality standards require the supplier to keep identifying information for supplied equipment, but your copy helps when an after-hours worker has not seen the delivery record. (CMS, DMEPOS Quality Standards.)

Do not sign a delivery ticket that lists equipment or supplies you did not receive. Ask for a corrected copy.

Choose the operating location using the manufacturer's and supplier's instructions. Check that the cord reaches without an extension arrangement the supplier has not approved. Keep tubing out of the walking path where possible. Secure cylinders in the holder or stand supplied for them. Do not improvise storage.

Remove smoking, candles, open flames, and other ignition sources from the oxygen area. MedlinePlus says oxygen makes materials burn faster and gives specific separation guidance for heat and flame sources. It also recommends working smoke detectors and a fire extinguisher. (MedlinePlus, Oxygen Safety.)

Keep the supplier label on the machine. Put the after-hours number beside it. Add the same number to the phones of the people covering the first week.

Day 2 to Day 3, the first full days: assign routine upkeep

Make a short maintenance sheet for this exact model. Use the supplier's written instructions, not a schedule copied from another machine.

List each family task separately. That may include checking tubing for kinks, checking the backup level, wiping an exterior surface, emptying or cleaning a bottle, or cleaning a filter. The correct tasks and intervals depend on the equipment. Ask the supplier to mark which tasks the family may perform and which require supplier service.

Put one person's name beside each task. Also name a second person who can take over. “The family will handle it” is not an assignment.

Keep a simple log near the equipment. Record completed upkeep, replacement supplies received, alarms, calls to the supplier, and any equipment exchange. Include the name of the person you spoke with and what was promised.

If a home care aide will help, ask the agency to place the permitted oxygen-equipment tasks in the service plan. Missouri DHSS guidance says an aide may assist with specified concentrator tasks such as cleaning tubing or a filter and adding water when those tasks are authorized within the service arrangement. Do not assume an aide will do them without checking the plan. (Missouri Department of Health and Senior Services, Home and Community-Based Services Policy Clarification Questions.)

Day 3 to Day 7, the week: test the failure path

Do a paper test before there is an alarm.

Start with the supplier. Confirm which number answers outside normal business hours. Ask what information the caller should have ready. Confirm whether the supplier repairs the unit in the home, exchanges it, or uses another service company.

Next, confirm the backup path. The National Institute on Aging advises families to include electrically powered durable medical equipment in emergency planning and to discuss alternate or backup equipment with the medical supply provider or clinician. (National Institute on Aging, Disaster Preparedness and Recovery for Older Adults.)

Write the steps in order:

Use the backup exactly as trained. Call the supplier's after-hours line. Give the model, serial number, alarm information, and remaining backup amount. Follow the discharge instructions for contacting the clinical team. Use emergency services when the discharge instructions identify an emergency or when the situation is immediately dangerous.

Do not try to open the concentrator housing, repair a regulator, refill a cylinder, or change the prescribed setting unless the supplier's written instructions specifically assign that action to the user.

Ask what happens during a power failure, a supplier phone outage, and a blocked delivery route. Missouri DHSS advises oxygen users to plan for alternate supplies and discuss continued service during emergencies with the oxygen supplier. (Missouri Department of Health and Senior Services, Preparedness Information for Oxygen Users.)

Keep one oxygen ownership page

By the end of the week, one page should hold the order, supplier contacts, equipment identifiers, rental or ownership status, approved upkeep tasks, replacement-supply process, backup instructions, and failure call path.

Review that page whenever the equipment, order, supplier, caregiver, or living location changes. Maintenance belongs to named people. The repair promise belongs to a named supplier. The backup must be present, understood, and ready before the machine goes quiet.
