Quick answers
Do I need a prescription for home oxygen therapy?
Yes. Home oxygen therapy requires a valid prescription from a licensed physician specifying the flow rate and duration of use. Our team coordinates directly with your doctor to confirm the order, verify insurance, and schedule delivery.
What is home oxygen therapy?
Home oxygen therapy delivers supplemental oxygen to patients with low blood oxygen levels, usually caused by COPD, pulmonary fibrosis, severe asthma, heart failure, or other chronic lung conditions. Oxygen can be delivered via concentrator (which pulls oxygen from room air), compressed tanks, or liquid oxygen systems — your physician and respiratory therapist choose the setup based on your prescription and lifestyle.
What types of oxygen equipment do you provide?
We provide stationary oxygen concentrators for home use, portable oxygen concentrators (POCs) for travel and daily errands, and portable oxygen cylinders. Our respiratory therapists help match the right equipment to your prescribed flow rate and lifestyle.
Who qualifies for home oxygen therapy?
Home oxygen is a prescription therapy. For Medicare or insurance to cover it, your doctor must document through an arterial blood gas or pulse oximetry test that your oxygen saturation falls below a specific threshold at rest, during exercise, or overnight. AHCEQUIP works directly with your physician to gather the paperwork and arrange delivery.
How does oxygen delivery and home setup work?
After we receive your prescription and verify insurance, a licensed respiratory therapist delivers the equipment to your home, installs it, and walks you (and any caregivers) through safe operation, cleaning, and emergency procedures. We schedule routine supply deliveries and maintenance visits so you don't have to track them.
Oxygen concentrator vs. oxygen tank — which is right for me?
Oxygen concentrators pull oxygen from room air and run on electricity — so there's nothing to refill. They're the standard for most home patients. Compressed oxygen tanks are portable cylinders, useful as backup during power outages or for short outings. Many patients use a stationary concentrator at home plus a portable option or tanks for travel. Your AHCEQUIP respiratory therapist will recommend the right setup.
Can I travel with a portable oxygen concentrator?
Yes. All major airlines accept FAA-approved portable oxygen concentrators (POCs) onboard. Notify the airline at least 48 hours ahead, pack batteries for 1.5× your flight time, and bring your prescription and letter of medical necessity. POCs also run on standard vehicle outlets for road trips. We stock FAA-approved POCs — contact us before your trip so we can confirm your equipment is airline-ready.
Do you offer portable oxygen concentrators for travel?
Yes. We carry FAA-approved portable oxygen concentrators (POCs) for air travel. We can help you pick a model based on your prescribed flow rate and travel patterns, and provide the documentation airlines require.
How do I clean my nebulizer?
After every use, rinse the nebulizer cup and mouthpiece in warm water and air-dry on a clean towel. Once a day, wash with mild dish soap and rinse thoroughly. Once a week, disinfect by soaking in one part white vinegar to three parts water for 30 minutes, then rinse with sterile or distilled water and air-dry. Replace the nebulizer cup every 6 months or as directed by your doctor.
How do I maintain my nebulizer?
Rinse the nebulizer cup and mouthpiece with warm soapy water after every use. Once a week, fully disinfect using the manufacturer-recommended solution (typically a vinegar-water mix or sterilization tablets). Replace the cup, tubing, and filter per the manufacturer's schedule — usually every 3–6 months. Our respiratory team walks you through the full routine at delivery.
