Oxygen therapy is needed when someone can't bring enough oxygen through the lungs to the bloodstream. They are necessary to work with two different methods of treating a patient's COPD or other medical conditions. There are two main types of oxygen therapy: pulse dose and continuous flow.Pulse dose is designed to work with a patient's inhaling and exhaling patterns. It uses a sensitive device that is triggered by a change in air pressure, which is caused by your own breath. It is designed to release a pulse of air, also known as a bolus, just at the right moment for you to breathe it in.
The rate at which these puffs of oxygen are released depends on your own breathing pattern. If you are walking fast and exerting energy, you will be breathing faster and heavier, which will cause the oxygen concentrator to release larger puffs at a quicker rate.
This is why pulse dose oxygen is used exclusively by portable oxygen concentrators. When using a portable concentrator, you can be up moving around, walking, and even getting some light exercise, such as riding a bike.
Portable models may also include continuous flow settings, for those who require a continuous flow dosage, who also want to be able to get around while getting their oxygen therapy.
