weight
These devices can be used wherever you want to go, so size and weight, as well as the method of transportation you choose, are major considerations. Generally, oxygen generators with greater power and higher output are heavier and larger. However, this does not necessarily prevent this lifestyle. Many products are also equipped with a convenient rolling cart or belt system for easy transportation.
For reference, the continuous portable device weighs about 20 pounds. Pulse flow devices tend to be much lighter, ranging from three pounds to 10 pounds in total.
Delivery/stream type
Based on the delivery of oxygenated air, there are two main types of units, pulse flow, and continuous flow. The pulsed streamer will periodically blow short air during each inhalation to deliver air to the patient. As a result, no oxygen is wasted. "Pulse flow or demand flow only delivers oxygen when the patient inhales. This can help reduce power consumption. Pulse flow is more common at night. Some people can use the additional function of pulse flow for continuous flow as needed." Langdon said the doctor.
In contrast, a continuous flow unit generates a continuous flow of oxygen. Dr. Langdon said: "One to five liters of continuous oxygen flow per minute is a common way to deliver oxygen continuously regardless of whether the patient inhales or not." These devices often have larger compressors and may waste some oxygen.
Battery Life
You can expect the medical oxygen concentrator to run for up to 4 to 5 hours after a battery charge. Smaller, lighter devices usually have shorter battery charging times, although many devices are equipped with additional batteries that can double off-grid life and car charging options.
Oxygen output
So far, the first consideration when buying an oxygen concentrator is how much oxygen the machine can release. Unlike oxygen tanks, which can deliver oxygen in almost any environment, Scott Marlow, a respiratory therapist at the Cleveland Clinic in Ohio, explained that the portable concentrator delivers a certain amount of oxygen for every breath. Most patients need about 400ml/min based on their diagnosis. It is important to discuss with your doctor your specific requirements and which machine will best keep your oxygen saturation levels stable.
