Yes, this battery-operated portable breathing machine also runs on AC and DC currents. It can be plugged into an electrical outlet if at home and if in the car, it can be charged through a DC power cord thus preserving the battery for outdoor use. Multiple power options of AC and DC current and rechargeable battery make it a convenient machine to have at home and outdoors. 

Three Power Supplies:

1. Single 8-cell battery (up to 5.5 hours for outdoor use);

2. Vehicle DC power (for vehicle use);

3. Wall outlet (for indoor use).

Attention Please:

Remove the battery from the unit while operating it by using the vehicle's DC power or AC currents through the home wall outlet. Alternatively, charge the battery only and stop turning on this mahine. This precaution ensures safe operation. 

Yes. This portable oxygen concentrator is battery-operated so that you can use it on the go. In addition, it can be powered by a motor vehicle's DC power source without the battery.

If your vehicle's input voltage is DC12V, it is recommended to either only charge the concentrator's battery without turning it on to prevent blowing the fuse, or alternatively, you can turn on the machine by the vehicle's DC power to get oxygen without the battery. By following these guidelines, you can ensure the functionality of the device and avoid any potential electrical issues.

Flow Control Settings and Pulse Volumes:

*Note:

Breath Rate: the number of breaths you take per minute.

Oxygen Volume Per Minute = Breathing Rate x Oxygen Volume Per Breath.

This portable oxygen concentrator (POC) has a maximum capacity of 1,000 milliliters (ml) per minute, and the actual amount of oxygen delivered with each breath depends on your flow setting and breathing rate. The POC operates on a pulse dose oxygen delivery system, meaning it delivers a specific amount of oxygen per minute based on your breathing pattern.

For instance, if you set the POC to level 1, it will deliver a total of 210 ml of oxygen per minute. If your breathing rate is 10 breaths per minute, the machine will provide 21 ml of oxygen with each breath. However, if your breathing rate increases to 30 breaths per minute, the POC will adjust the oxygen bolus size to 7 ml per breath to maintain the total delivery of 210 ml per minute.

Portable oxygen concentrators function based on the same principle as stationary concentrators. They utilize a miniaturized air compressor to pressurize the surrounding air and pass it through small molecular sieves. These sieves have the ability to trap nitrogen, which constitutes approximately 78% of the air. Once the nitrogen is removed, the remaining gas is primarily oxygen, which can be delivered to the patient through a cannula or mask. The trapped nitrogen is then released back into the environment.

The technology employed in this process is called pressure swing adsorption (PSA). It separates different gas species from a pressurized mixture based on their molecular characteristics and affinity for an adsorbent material. Unlike cryogenic distillation techniques, PSA operates at near-ambient temperatures. Specific adsorptive materials, such as zeolites, activated carbon, or molecular sieves, are used to selectively adsorb the target gas species at high pressure. The process then switches to low pressure to desorb the adsorbed material.

Our portable oxygen concentrator is a battery-operated device that provides supplemental oxygen to individuals who require higher oxygen concentrations than what is available in the ambient air. It draws oxygen from the immediate environment, eliminating the need for refillable oxygen canisters or tanks, which simplifies maintenance and upkeep.

It weighs 4.37 lbs (1.98 kg) with the single battery, about the equivalent of 2 bottles of mineral water (33.81 Fl Oz). Its small size and lightweight make it easy to wear in a carry bag with a shoulder strap.

The maintenance of the portable oxygen concentrator is minimal. We recommend replacing filters that can be found on the bottom of the machine. Generally, this will be after several months, but is dependent on its usage and the climate.

Yes, the package will come with a shoulder bag specifically designed for the unit.

Yes. The portable oxygen concentrator (POC) is specifically designed for 24/7 use, including during sleep. It supports oxygen inhalation more efficiently for a whole day and night when plugged in. 

Equipped with intelligent delivery technology, the POC offers pulse dose delivery in 1-5 flow settings, making it an ideal choice for sleep therapy. This technology provides flexibility by adjusting the oxygen bolus size as your breath rate slows during sleep. It also detects shallow breaths during sleep and delivers bolus doses accordingly, ensuring you receive the required amount of oxygen in liters per minute.

To ensure uninterrupted use throughout the night, it's important to consider the battery running time, which typically ranges from 1.5 to 5.5 hours. It's advisable to ensure you have enough power to last through the night. If you require a higher oxygen flow setting, you can remove the battery and use a power cord to connect the POC to an outlet for continuous operation.

Yes.

Portable oxygen concentrators are smaller and lighter, more convenient for travel and on-the-go use. They are battery-powered and can operate without being plugged into an electrical outlet. They are suitable for people who require more mobility.

Home stationary oxygen concentrators are larger and heavier compared to portable ones. They are designed for use at home and need to be plugged into a wall outlet for operation. Stationary concentrators typically offer higher flow rates and can deliver 5 or 10 liters of oxygen per minute. They are recommended for those who require higher doses of oxygen and need a continuous flow of oxygen.

All in all, choose an oxygen concentrator according to your needs. (For those who need long-term oxygen therapy and have enough budget, better prepare a stationary oxygen concentrator for home use and a portable oxygen concentrator for outdoor use.)

The difference between pulse flow and continuous flow in an oxygen concentrator is how the oxygen is delivered.

Pulse flow, also known as on-demand or intermittent flow, delivers oxygen in short bursts or pulses when you inhale. It is designed to match your breathing pattern and conserve oxygen, making it more efficient for portable use and for individuals with lower oxygen requirements or active lifestyles. Pulse flow is generally used for portability exclusively because it conserves oxygen to extend battery life or activity time. 

Continuous flow, on the other hand, delivers a constant and steady flow of oxygen regardless of your breathing pattern. It is typically used for individuals with higher oxygen requirements or those who need a continuous supply of oxygen, such as during sleep or rest at home.

*Note: Our portable oxygen concentrator offers pulse dose delivery.  (When there is no breath detected, the alert will be triggered and the device will offer continuous flow.)
