What is a Portable Oxygen Concentrator?
Portable Oxygen Concentrators are lightweight medical devices that deliver supplemental oxygen to people who need it while maintaining mobility. Unlike traditional oxygen tanks, POCs draw in ambient air, filter it, and provide concentrated oxygen continuously or in pulses--no refills required. They’re designed to support active lifestyles, whether you’re at home, running errands, or traveling.

Flow Type: Continuous vs. Pulse Dose
When selecting a POC, it’s important to understand flow type. Continuous flow units deliver a steady stream of oxygen, ideal for sleep or patients prescribed a constant rate. Pulse dose models detect your breathing pattern and deliver oxygen only when you inhale--conserving energy and extending battery life. Your doctor’s prescription will specify which type is right for you.

Battery Life & Power Options
Battery performance varies widely between models. Smaller, ultra-light concentrators may run 3–5 hours on a single charge, while larger ones can exceed 10 hours with extended batteries. Most units can operate on AC or DC power (car adapters, for example), giving users flexibility for travel or daily use without interruptions.

Weight, Size & Portability
POCs range from pocket-sized models under 4 lbs to more robust options around 19 lbs that provide higher oxygen output. Consider how and where you’ll use it--lighter models are best for quick outings, while heavier ones suit longer trips or higher oxygen needs. Many come with carrying cases, backpacks, or rolling carts for added convenience.

FAA Approval & Travel Readiness
If you plan to fly, check for FAA approval--most leading POC brands like Inogen, CAIRE, and Rhythm have models cleared for in-flight use. Always carry extra batteries, power cords, and your prescription when traveling. A little planning ensures you stay oxygen-ready wherever life takes you.
