Oxygen as a Service
Understanding how homecare oxygen therapy really works
When a patient is first prescribed home oxygen, it can feel overwhelming. New equipment in the home. Tubing, flow rates, cylinders, concentrators, portable machines, medical-aid authorisations, delivery arrangements, and instructions from a specialist. For many families, the first thought is simple:
"How does all of this actually work?"
At Respocare, we believe a patient should never feel alone when oxygen becomes part of daily life. That is why we see oxygen therapy as more than a product. We see it as a service.
A stationary concentrator, a portable oxygen machine and a backup cylinder each play an important role. But the real value lies in how those pieces are brought together — explained, delivered, supported and managed around the patient's life. That is what we mean by Oxygen as a Service.
1. What is homecare oxygen therapy?
Homecare oxygen therapy is prescribed when a patient needs additional oxygen at home to maintain healthy oxygen levels. It is commonly used by people living with chronic respiratory conditions, those recovering after hospital, or anyone whose oxygen levels may be too low.
Home oxygen should only ever be used when prescribed by a qualified healthcare professional. The NHS notes that home oxygen means breathing air with more oxygen than normal, through a mask or tube connected to a device — and that it should only be used under prescription, because incorrect use can be dangerous.
For patients, this means oxygen therapy is never something to guess at. It must be tied to a proper prescription, the correct flow rate, the right equipment and clear instructions. At Respocare, the process always starts there — with the script. From that point, our role is to make the therapy practical, understandable and well supported in the home.
2. The three building blocks of home oxygen
Most patients picture oxygen therapy as a single machine. In reality, it usually works best when different solutions support different parts of life:
A stationary oxygen concentrator — for reliable everyday use at home.
A portable oxygen machine — for mobility and independence.
An oxygen cylinder — for backup, travel and specific needs.
Each one matters, but none should be seen in isolation. The goal is not simply to deliver equipment — it is to build a safe, reliable oxygen system around the patient.
3. The stationary concentrator: the home base
The stationary concentrator is usually the foundation of home oxygen therapy. It stays in the home and supplies oxygen for everyday use, working by drawing in room air, separating out the nitrogen, and delivering oxygen-enriched air to the patient. The Cleveland Clinic explains that concentrators separate nitrogen from the surrounding air so you can breathe oxygen-enriched air, with some built for stationary use and others designed to be portable.
For many patients, the stationary concentrator supports therapy while resting, sleeping, reading, watching television, recovering after activity, and moving through daily routines.
Because it runs on electricity, patients also need to understand what to do during a power interruption — and this is exactly where service becomes essential. A concentrator should not simply be dropped at the door. It needs to be placed correctly, connected correctly, explained clearly and supported properly. Patients need to know:
Where the machine should stand.
How the tubing works.
What the prescribed flow rate means.
How to recognise alarms or issues.
When and how to contact support.
How backup oxygen fits into the plan.
That is why Respocare treats delivery as part of care — not just logistics.
4. Portable oxygen: moving beyond the home
For many patients, oxygen therapy can feel as though it limits their freedom. Portable oxygen exists to change that. A portable machine supports patients when they need oxygen away from the main home concentrator — attending a family event, visiting a doctor, doing the shopping, or simply feeling less confined by their condition.
The American Lung Association explains that portable oxygen concentrators can help patients who need supplemental oxygen away from home, extracting oxygen from the surrounding air in much the same way a home concentrator does.
But portable oxygen still needs proper education. Not all portable machines work the same way: some deliver pulse-dose oxygen — releasing oxygen when the device senses a breath — while some patients need continuous flow, depending on their prescription. A portable machine is never a lifestyle gadget. It is a medical device, and the right one must match the patient's oxygen needs, specialist guidance, mobility goals and safety requirements.
Portable oxygen is about more than movement. It is about dignity — helping patients stay connected to family, appointments and the moments that matter.
5. Oxygen cylinders: the backup you should never ignore
Cylinders remain one of the most important parts of home oxygen therapy. A cylinder holds compressed oxygen gas stored under pressure; the Cleveland Clinic explains that compressed oxygen is kept in a metal cylinder and usually released through a regulator that controls the flow.
In South Africa, this matters a great deal. A stationary concentrator needs power; a cylinder does not. That makes the cylinder an essential safety layer during load-shedding and power interruptions. Cylinders may be used during power failures, for short journeys, as everyday backup, or whenever a healthcare professional advises a different setup.
But a cylinder is only useful if the patient and family know how it fits into the plan — where it is stored, how long it lasts, when to use it, how to read the gauge, when to request a replacement, and what to do in an emergency.
A backup system is only truly a backup if it is ready, understood and accessible.
6. The hidden truth: equipment is not therapy
This is the part many people overlook. A stationary concentrator is a machine. A portable device is a machine. A cylinder is a container of medical oxygen. Homecare oxygen therapy is not created by equipment alone — it is created by the system around the equipment.
That system includes receiving the script, understanding the prescribed needs, communicating with the patient and family, preparing the right equipment, managing authorisation, arranging fast delivery, setting up the device, explaining how it all works, supporting the patient afterwards, and troubleshooting when something goes wrong.
This is the difference between supplying oxygen and delivering healthcare. Patients do not only need oxygen — they need confidence, clarity, reassurance, and a team they can reach when they are unsure.
7. From script to same-day delivery
For most patients, oxygen therapy begins with a script from a specialist — and that script is far more than paperwork. It is the starting point of care.
Once a patient needs oxygen, time matters. Families may be anxious, patients may be breathless, hospitals may be preparing for discharge, and specialists need confidence that the home setup will be handled properly. At Respocare, our goal is to move with urgency and care from prescription to delivery — and, wherever possible, that includes same-day delivery, setup and patient education.
A typical patient journey runs from the script being received, to the oxygen requirement being reviewed, the right equipment prepared, the family contacted, delivery arranged, the technician completing the setup, the patient shown how to use everything, and support remaining available after installation. Because oxygen therapy is never just about placing a device in a room — it is about making sure the patient can use the therapy safely at home.
8. Why patient education is part of the therapy
Education is one of the most important parts of home oxygen care. Patients should understand their therapy well enough to feel safe — but not so burdened that they feel overwhelmed. Good education helps a patient understand what their oxygen is for, which device to use at home and which to use when leaving, how the cylinder fits into the backup plan, why the flow rate must follow the prescription, what to do if breathlessness worsens, and who to contact for help.
Lung Foundation Australia explains that oxygen therapy helps raise blood oxygen levels and may give patients more energy for everyday activities, while supporting vital organs such as the brain and heart. But the benefit depends entirely on correct use — which is why education is not a nice-to-have. It is part of safe care.
When patients understand their therapy, they feel more in control, families feel less anxious, and specialists have greater confidence that the patient is supported at home.
9. What patients should never do
Oxygen is a medical therapy, and it must be respected. Patients should never:
Change a prescribed flow rate without medical guidance.
Use oxygen simply because they "feel it might help," unless it has been prescribed.
Buy oxygen equipment and self-manage therapy without a healthcare professional involved.
Ignore worsening symptoms.
Treat oxygen equipment as ordinary household equipment.
The NHS specifically warns that buying oxygen online and using it without a prescription can be dangerous. Patients should always follow the advice of their specialist, doctor or respiratory care team — and Respocare's role is to support that prescription and make the therapy work safely at home.
10. How the three solutions work together
A strong home oxygen plan is rarely about choosing only one device. It is about understanding the role each one plays.
Solution | Its role in the plan |
Stationary concentrator | The main home oxygen source. Supports daily use indoors over longer periods, including rest and sleep, according to the prescription. |
Portable oxygen machine | Supports movement and independence, helping patients leave home while still receiving oxygen — depending on device type and prescription. |
Oxygen cylinder | Provides backup and flexibility — especially important during power failures or when a cylinder suits a specific situation. |
Together, these three form a practical oxygen ecosystem. But service is what connects them — turning equipment into a genuine care pathway.
11. Oxygen as a Service: what it means at Respocare
For Respocare, Oxygen as a Service means taking responsibility for far more than the equipment. When oxygen enters a home, it affects the patient, the family, the daily routine, the bedroom and living space, the power supply, the travel plan and the emotional wellbeing of everyone involved. So we commit to:
Responding with urgency.
Understanding the importance of the script.
Delivering and setting up equipment properly.
Educating patients and families.
Supporting patients after delivery.
Working alongside healthcare professionals.
Treating every oxygen setup as a responsibility.
In healthcare, service is not small. It is often the difference between confusion and confidence — between oxygen being delivered, and oxygen therapy being understood.
12. Questions worth asking about your therapy
Patients and families should always feel comfortable asking questions. A few useful ones:
What oxygen flow rate has been prescribed for me?
Should I use oxygen during sleep, during activity, or throughout the day?
Which device should I use at home — and do I need portable oxygen?
Do I have a backup cylinder, and what should I do during a power failure?
Who do I contact if the machine alarms, or if a cylinder runs low?
What should I do if I feel more breathless than usual — and when should I call my specialist?
These questions are not a sign of uncertainty. They are part of responsible care. Informed patients are more confident patients.
13. When to contact your healthcare provider
Patients should contact their doctor, specialist or emergency services if they experience serious or worsening symptoms — such as sudden breathlessness, chest pain, confusion, blue lips or fingertips, severe weakness, or oxygen levels that are concerning based on the guidance they were given.
Respocare supports the oxygen equipment and service pathway, but clinical changes must always be discussed with the appropriate healthcare professional. Home oxygen therapy works best when the patient, family, specialist and oxygen provider all work together.
In closing: oxygen therapy is built on service
Homecare oxygen therapy is not just a concentrator, a portable machine or a cylinder. It is about how those tools come together around the patient. The stationary concentrator provides the foundation. The portable machine supports mobility. The cylinder provides backup and peace of mind. But service is what turns all of it into real homecare oxygen therapy.
At Respocare, that is what we are here for: to help patients understand their therapy, to support families, to work with specialists, to deliver with urgency, and to educate with patience — treating oxygen with the seriousness, dignity and care it deserves.
Because oxygen is not just a product. It is a service. And when it is done properly, it helps patients feel safer, more supported and more confident at home.
Frequently asked questions
What is homecare oxygen therapy? Prescribed oxygen support used at home for patients who need extra oxygen due to low oxygen levels or certain medical conditions. It should only be used under the guidance of a qualified healthcare professional.
What's the difference between a stationary and a portable concentrator? A stationary concentrator is used inside the home and runs on electricity. A portable machine helps patients receive oxygen while moving outside the home — depending on their prescription and oxygen needs.
Why do oxygen patients need cylinders? Cylinders act as backup oxygen, especially during power failures or when a concentrator isn't suitable. They do not rely on electricity — an important advantage in South Africa.
Can I change my oxygen flow rate myself? No. Patients should never change their flow rate unless instructed by their doctor, specialist or respiratory care team.
What does "Oxygen as a Service" mean? It means therapy is supported by far more than equipment — including prescription handling, delivery, setup, education, backup planning, troubleshooting and ongoing support.
Does a portable machine replace a home concentrator? Not always. Many patients still need a stationary concentrator as their main source at home; a portable machine supports mobility. The right setup depends on the prescription.
Who should I contact if I'm unsure about my therapy? Contact your oxygen provider for equipment questions, and your doctor or specialist for medical questions, symptoms or any change in your condition.
