Quick Answer
An oxygen concentrator should only be selected against the written prescription, especially the flow rate, daily duration and any instructions for backup oxygen.
When oxygen is prescribed at discharge, speed matters – but accuracy matters more. The family needs the exact prescription, a safe power plan and a clear handover rather than a generic “oxygen machine.”

Start with the Right Decision
A 5-litre and a 10-litre concentrator are not interchangeable labels. The prescribed litres per minute (LPM) and the clinical plan determine which equipment is suitable. Do not change flow settings, assume a different model is equivalent or use an unapproved setup because it appears easier. Ask the treating team to explain the written prescription and backup plan.
What to confirm before booking
- the prescription’s LPM, daily duration and prescribed interface
- the exact concentrator model and its stated flow capacity
- safe socket, ventilation clearance and a plan for power interruptions
- tubing, nasal cannula or other consumables included and the handover process

Should You Rent or Buy?
Renting can suit short-term respiratory support or a changing clinical plan; buying may suit a longer prescription when the model requirements are stable. In either case, the decision should follow the prescription and current service terms, not a general internet recommendation.
A Practical Booking Checklist
- Keep the prescription, discharge instructions or therapist recommendation ready where equipment is clinically prescribed.
- Ask for the exact model and included accessories in writing.
- Confirm the delivery route, room setup, handover and service contact before the booking is finalised.
- Ask about the current rental period, extension process, collection terms and purchase option where relevant.
5L, 10L, Continuous Flow or Pulse Dose?
The litre rating is a machine’s maximum flow capacity, not the amount every patient should receive. Use only the clinician-prescribed flow. Some portable machines deliver pulse-dose rather than continuous oxygen and may not suit every prescription, sleep use or breathing pattern. At higher prescribed flows, confirm that the selected machine maintains the required oxygen concentration.
- Check the flow-meter and humidifier setup when prescribed.
- Learn alarm meanings, ventilation space and cleaning.
- Keep the prescribed backup oxygen and power-cut plan ready.
- Separate equipment-support contacts from clinical contacts.
Frequently Asked Questions
Can I choose a 5L or 10L concentrator myself?
No. The clinician’s written prescription should guide the flow capacity and setup. If the prescription changes, confirm the equipment with the treating team and provider.
What should happen at delivery?
Ask for a demonstration of the machine’s basic operation, alarms and cleaning instructions, plus a clear service contact. Clinical questions about flow and patient status should go to the treating team.

How to Compare Quotes and Support
A clear concentrator quote should identify the stated flow-capacity model, included tubing or interface, delivery and handover scope, service contact, rental term and current availability. It should never replace the prescription or promise a clinical outcome.
When to Involve the Care Team
Contact the treating team urgently if the patient’s breathing, alertness or prescribed oxygen requirement changes; do not try to solve a clinical change by changing equipment yourself.
- Keep the written prescription available at delivery.
- Ask how to report an equipment alarm or fault.
- Confirm the approved backup plan with the clinical team.
