How to Choose and Features of a Respiratory Oxygen Concentrator

RESPIREASY Oxygen Concentrator Features:

Oxygen Generation:

An oxygen concentrator extracts oxygen from ambient air (typically containing 21% oxygen) and concentrates it to a purity of 90-95%. This process is called Pressure Swing Adsorption (PSA).

Portable & Stationary:

Portable Oxygen Concentrator (POC): (Portable models: REA REC RES RE-Y5 RE-Y7)

These lightweight, battery-powered devices are designed for mobile and outdoor use. They are typically used by individuals who need oxygen during travel, exercise, or daily life.

🔋 Highly practical for outdoor use, travel and driving friendly: Supports car and home power sources, lithium battery with three operating modes, multi-power compatibility, meeting the needs of travel, home, and emergency use.

🌿 Energy efficient, continuous oxygen supply: Uses high-concentration molecular sieves, achieving an oxygen purity of 90%±3%. Maintains high-purity oxygen output even after prolonged use, suitable for COPD, asthma, and post-operative recovery. Quiet and undisturbed for nighttime use, ≤ 42 dB for enhanced comfort.

🧳 Portable: Meets TSA (Transportation Security Administration) requirements for portable oxygen devices. Lightweight and portable, easy to carry, can be worn on the back or carried by hand, suitable for multiple scenarios (home, car, walking).

💨 High-Efficiency Oxygen Generator: Employs third-generation molecular sieve adsorption technology, adjustable oxygen flow rate and alarm system, modular design, and replaceable filter.

Stationary Oxygen Concentrator: (Stationary oxygen generator models: RE-R1L RE-E1L RE-P2L RE-S2L)

These are larger stationary devices that provide higher flow rates and are typically used in homes or medical facilities.

🧠Flow Rate Selection:For those requiring medium to high flow rates (1-9 L/min) oxygen therapy at home or in nursing homes, this is a flexible option. The modern interface and remote control make it easy for caregivers or family members to operate.

💨High Practicality:The 2-in-1 nebulizer function means users can simultaneously perform oxygen therapy and nebulization therapy (such as respiratory humidification and nebulized medication). Eight-layer filtration ensures high air cleanliness, thus saving on equipment costs. The combination of nebulization and oxygenation functions allows for all-day use, enhancing the overall value of the equipment.

🩺Energy Efficiency:High oxygen concentration output (approximately 96%) coupled with continuous operation indicates suitability for relatively demanding oxygen therapy scenarios. Its lightweight design facilitates use in home/light institutional settings, providing more capacity for higher oxygen demands. The device's high mobility (handle + casters) allows for easy movement between rooms.

Flow Rate:

Oxygen concentrators are typically adjustable, with flow rates ranging from 1 liter per minute (LPM) to 10 LPM or higher, depending on the model. The appropriate flow rate is determined by healthcare professionals based on the user's needs.

Battery Life (Portable Devices):

Portable devices typically come with rechargeable batteries, offering battery life ranging from 1 to 8 hours depending on flow rate and battery capacity. Some models also support onboard charging, making them ideal for travel.

Noise Level:

Modern oxygen concentrators are designed for low operating noise. Stationary concentrators are generally quieter, while portable concentrators, although relatively quiet, may emit a slight hum.

Size and Weight:

Portable devices are small and lightweight, typically weighing between 2 and 10 pounds, making them easy to carry. Stationary devices are larger and require more space.

Alarms and Reminders:

Oxygen concentrators are equipped with built-in alarms that notify the user of problems such as low oxygen purity, power failure, or low battery (for portable devices).
