What Is Dynamic Oxygen Delivery?
Humans breathe by what’s known as the Nasal Cycle. This is the alternating of inhaling between the right and left nostrils. In simple terms, we don’t breathe through both nostrils simultaneously.
Don’t believe us?
The Nasal Cycle is displayed in the graph below. This graph is the result of a patient’s actual breathing pattern from a study conducted at Stanford University.
As you can see, it’s easy to notice which nostril is inhaling and which is resting.
We don’t notice the Nasal Cycle because it occurs in our subconscious. Similar to how our bodies breathe on their own, and our heart beats on its own, the Nasal Cycle occurs automatically so each nostril can rest and rehydrate.
Dynamic Oxygen Delivery is therapy completely in-sync with our body’s natural way of breathing, unlike all standard oxygen delivery systems today.
How Does It Work?
In real-time, our technology detects which nostril is inhaling and which is resting. Then fully delivers 100% of a patient’s prescribed oxygen through the dominant nostril and straight into the lungs.
The difference between Dynamic and Standard Oxygen Delivery is demonstrated in the two-sided graph below.
The Dynaris Apogee System is the world’s ONLY oxygen therapy capable of delivering up to 100% of prescribed oxygen efficiently.

What Patients Are Saying
In the video below, United States Veteran and oxygen patient, Art, explains why he trusts Dynaris’ Apogee System for his oxygen therapy.
“Within a week of switching to the Dynaris Apogee, I already noticed improvements. I could actually feel the therapy working better, and I’m not so tired all day. On the Apogee, I can go much farther on my walks around the neighborhood, and go twice as long without switching out cylinders. On previous oxygen systems, my pulse ox readings would record between 82 and 93. This week I visited my Doctor and had my oximeter recorded at 98! My doctor was so surprised she actually checked it twice on a different oximeter!”
“The Apogee portable oxygen system solves a real problem that current research has brought to light. Oxygen has been delivered through a nasal cannula equally to both nostrils, 50-50. This means that if one nostril is closed as often is the case that only a portion of the oxygen prescribed may be therapeutic. Also, delivering oxygen to the closed nostril can unnecessarily dry and irritate that nostril. I also enjoy knowing that I’m not wasting my oxygen to the atmosphere and thereby greatly extending the range of my portable ambulatory oxygen system. I love the Apogee.”
“I just love the blue bag. The shade is spectacular and it has a little pocket to store credit cards, ID, and oximeter without creating a lot of bulk. I used the Apogee from 3 pm – 11 pm… And it lasted that whole time! Amazing. I did still “feel the weight” after so many hours, but NOTHING like with the POC or even smaller continuous O2 tank.”
What The Experts Are Saying
“I learned about Dynaris’ nasal cycle research several years ago. I’m glad to hear they now have perfected an oxygen delivery system that senses which nostril you’re breathing out of and only delivers 02 to that nares. This efficient targeted delivery should not only enhance oxygen saturation but will virtually cut oxygen use by half. A brilliant discovery!”
“Oxygen therapy has been a huge part of medical treatment, but little has been done to improve it over the last few decades. The founder, Lon Aylsworth has made it his mission to modernize the understanding and delivery of oxygen. The design improvements are revolutionary and brilliant, but you also wonder why no one ever took this approach before. We are all looking forward to the breakthroughs that will come as a result of this new approach to oxygen therapy.”
“Patients no longer need to suffer nasal irritation for the benefits of life-sustaining oxygen.”

How does the Apogee’s portable oxygen system compare to portable oxygen concentrators (POC) of similar size and weight?
The Apogee is a fraction of the cost of a POC. At around 4.5 lbs., is quieter and should have several hours more range than a similarly sized POC. In addition, the Apogee delivers a ‘uniform’ dose of oxygen to the most open nostril at nearly 100% oxygen purity. The Apogee’s volume remains the same with every breath.
POC’s with a built-in conserver deliver minute volume (a constant volume of oxygen produced each minute) and reduce the volume sent as the breath rate increases. They may only produce 82% oxygen. Because they always deliver oxygen to both nostrils — even when one is blocked — POCs may not meet the prescribed dosage.
What are some of the advantages of the Apogee’s Selective Oxygen Delivery?
1. The most important advantage of selective delivery is receiving oxygen consistently regardless of whether one side of the nose is completely blocked. This is important because if your oxygen is being split 50% to each nostril and one nostril becomes blocked then only half of the oxygen will be therapeutic.
2. Because the Apogee does not flow any gas to the congested nostril, dryness and irritation may be substantially reduced.
Why do humans usually breathe out of a dominant side of the nose?
Both anatomical and physiological factors account for uneven nasal airflow. Examples of fixed causes may include a deviated septum, nasal polyps, or enlarged nasal turbinates. Physiological factors may be caused by allergies, body position and the nasal cycle. We nasal cycle throughout the day and night for periods of 20 minutes to several hours.
How do oxygen systems using today’s standard nasal cannula differ from the cannula used by the Apogee?
Nasal cannulas are the tubes that deliver oxygen from the oxygen source to a patient’s nose. Nasal cannulas were first introduced in 1948 and, until now, little has changed in their operation. The standard nasal cannula has a single hose that separates itself into a left and right nasal prong. Studies show that this results in the oxygen being split evenly and delivered to each nostril at the same time. The Apogee’s nasal cannula, although it may look like a standard nasal cannula, has two tubes fused together, one entering each nostril. Each nasal airway is sensed separately, and the full oxygen dosage is then sent directly to the most receptive nostril.
Why until only very recently was there little information about the nasal cycle?
The nasal cycle was first described in a medical text in 1895. For nearly 100 years thereafter, there was little study on this subject — possibly because there was no way to continuously observe nasal airflow in real-time. The inventors of the Apogee at Dynaris discovered how the nasal cycle occurs inadvertently after inventing and patenting a device to improve the way sleep laboratories measure nasal breathing for sleep apnea patients. At first, they thought their machine was broken because it would often only detect airflow out of one nostril at a time. After research and testing of hundreds of patients at the Stanford University Sleep Center, the nasal cycle was rediscovered. The graph shown on the homepage of this website records a real patient’s nasal airflow pattern at Stanford.
The nasal cycle is now widely studied throughout the world. It is mentioned in publications, medical textbooks, and even Wikipedia.
What are the most important factors to consider when comparing pulse oxygen conserving systems?
1. The size of oxygen bolus (flow amount) delivered for each breath. Many units deliver a ‘minute volume’ so the faster you breathe, the smaller the bolus of oxygen becomes. The Apogee, on the other hand, delivers a ‘uniform pulse dose’ so that the bolus size remains constant regardless of breath rate.
2. The ability to detect inhalation at the earliest moment is critical to optimize therapy because only the first portion of inhalation will get deep enough into the lungs where gas exchange occurs. Units that sense and deliver late may only fill up the dead space in the airway. The Apogee’s dual sensors detect and deliver the oxygen before many oxygen systems can even begin to detect that inhalation has begun.
3. The purity of the oxygen being delivered. Some concentrators that are exceedingly small can only deliver oxygen purity that is less than 85% whereas oxygen tanks deliver about 99% purity.
