Oxygen Therapy
Home oxygen therapy helps people with COPD, heart failure, pulmonary fibrosis, and other conditions maintain healthier oxygen levels during daily activities and sleep. If you've recently received a prescription, you may have questions about how it works and how it fits into life at home.
Why Oxygen Is Prescribed
Low blood oxygen (hypoxemia) strains the heart and brain over time. Supplemental oxygen doesn't cure lung disease, but it can reduce shortness of breath, improve energy, and protect vital organs when levels drop below targets set by your pulmonologist.
Oxygen is prescribed based on testing—usually pulse oximetry or arterial blood gas results—at rest, during exertion, and sometimes during sleep.
Types of Home Oxygen Equipment
Stationary Oxygen Concentrators
These plug into household electricity and produce concentrated oxygen from room air. They're the main source of oxygen for many patients at home, delivered through long tubing to reach different rooms.
Portable Oxygen Concentrators
Battery-powered portables let you leave the house for appointments, errands, and social activities. Flow settings and battery life vary by model—match the device to your prescribed liter flow and typical outing length.
Oxygen Cylinders
Compressed gas cylinders serve as backups during power outages or for patients who need higher flows some concentrators can't deliver. Store them upright, secure, and away from heat sources.
Safety Rules Every User Should Follow
Oxygen supports combustion—it does not burn itself, but it makes fire spread faster and hotter.
- No smoking in the home or near oxygen equipment
- Keep oxygen tubing away from stoves, candles, fireplaces, and space heaters
- Do not use petroleum-based products on your face near the cannula; water-based moisturizers are safer
- Ensure working smoke detectors and a fire extinguisher
- Notify your utility company that oxygen is in use for priority during outages
Daily Living with Oxygen
Tubing management takes practice. Long tubing allows movement around the house but creates trip hazards—route it along walls and secure with clips. Portable units free you for outings; plan charging and carry extra batteries for longer trips.
Nasal cannulas and tubing need regular cleaning and replacement. Humidifier bottles on concentrators require distilled water and daily emptying to prevent bacteria.
Travel and Lifestyle
Many patients travel with portable concentrators by car and air, but airlines have specific approved device lists—verify before booking. Pace activities, use oxygen as prescribed during exertion, and keep follow-up appointments to adjust flow rates as your condition changes.
Prescription and Resupply
Oxygen equipment requires a prescription and ongoing medical follow-up. Insurance typically covers rental or purchase with documented necessity. We coordinate with physicians and help patients in Miami and South Florida get set up with concentrators, portables, and backup supplies.
