Portable Oxygen Concentrator Pulse vs Continuous Flow

When deciding what kind of oxygen concentrator is best for you, it is important to determine with your doctor what kind of oxygen delivery best meets your needs: Pulse dose vs. Continuous flow.

The Difference between Continuous and Pulse Flow 

Pulse dose oxygen delivery is based on breathing and inhaling, this automatically tells your oxygen delivery to match your breath rate. pulse dose output is determined by the size of the individual pulse called a bolus and is measured in milliliters per breath rather than liters per minute. pulse dose oxygen is more established, pulse dose mechanisms utilize an oxygen conserver and other technology to deliver oxygen to the patient based on the breathing rate and other factors.

This sensor determines when the patient begins inhaling and delivers the oxygen pulse dose at that exact moment.  When an oxygen concentrator is said to be a “single-solution” for on-the-go, at home and during sleep, it usually employs pulse dose oxygen technology so that it can deliver the proper amount of oxygen during all phases of daily activity and during rest.

Continuous flow on the other hand delivers oxygen at a constant adjustable rate, of the patients breathing measured in liters per minute.  For a continuous flow portable oxygen concentrator, imagine a water fountain: If an individual stands in front of a water fountain flowing at 1 liter per minute, they don’t actually drink one full liter of water. The amount of water a person drinks is estimated by the number of sips and the size of the sip. The rest of the water is wasted. The same applies to continuous flow oxygen; the net amount of oxygen inhaled is a combination of the flow rate, the number of breaths and the size of the breaths. 

A continuous provides a steady stream of oxygen at the set flow rate. This ensures the user receives a consistent oxygen supply with each breath. Most portable oxygen concentrators with continuous flow settings offer adjustable flow rates, typically ranging from 0.5 to 3 LPM or higher. It is suitable for a wider range of needs than pulse flow oxygen, such as for those who need oxygen during rest, activity, and sleep. Some POCs also offer pulse flow settings to help conserve oxygen and extend battery life. 

How to Choose

When it comes to the time to talk to your provider about choosing the right oxygen concentrator for you keep in mind the difference between pulse dose vs. continuous flow oxygen, it is also important to consider how you would like to use the oxygen: on the go, at home or just for sleep. Pulse dose oxygen concentrators seem to be preferable for doing a number of different things, but continuous flow portable oxygen concentrators may be a sufficient option, particularly if breathing will remain relatively constant. 

Oxygen Output and Flow Type:
Oxygen output is the most crucial factor when selecting a POC. Ensure the device meets your doctor's prescribed oxygen flow rate and delivery method (pulse or continuous flow). Consider investing in a pulse oximeter to monitor your oxygen saturation levels at home.

Battery Life and Power Options:
Opt for POCs with a battery life of at least 3-6 hours per charge for optimal freedom and mobility. Look for models offering extended battery packs and AC/DC power options for charging flexibility and prolonged use.

Size, Weight, and Portability:
Compact, lightweight designs under 5 pounds are ideal for active lifestyles and easy transportation. However, ultra-portable units may have reduced battery life and oxygen output compared to larger models.

Noise Level:
For discreet use in public settings, choose POCs with sound levels around 42 decibels or lower. The quieter operation ensures the device blends into background sound without drawing unwanted attention.

In conclusion, a portable oxygen concentrator is a valuable medical device providing a medical-grade oxygen supply for individuals with respiratory conditions. These devices have evolved from stationary machines to highly mobile and user-friendly devices, enabling individuals to maintain mobility and independence while receiving the necessary oxygen support.

Understanding the basics of a portable oxygen concentrator, including its function, benefits, and different types, is vital for individuals considering or already using these devices. By delivering concentrated oxygen directly to users, portable oxygen concentrators enhance overall well-being and enhance the quality of life for individuals with respiratory conditions.
