Sleep apnea is a widespread condition in which breathing repeatedly stops or becomes shallow during sleep. The standard treatment usually consists of CPAP therapy , in which continuous positive airway pressure keeps the airways open. However, there are situations in which supplementing CPAP with oxygen can be beneficial. Patients who still suffer from low oxygen levels despite CPAP can benefit from additional sleep apnea oxygen therapy.
This combination therapy is not suitable for everyone, however, and is only an option in specific cases. Below, we examine when oxygen supplementation is beneficial, what its advantages and risks are, and why modern devices like those from VARON can make everyday life easier for patients.

Understanding sleep apnea and oxygen levels
Obstructive sleep apnea (OSA) is characterized by repeated pauses in breathing due to blocked airways. This leads to a drop in blood oxygen saturation. Low oxygen levels at night can place a significant strain on the cardiovascular system and, in the long term, increase the risk of high blood pressure, heart attack, or stroke.
Besides OSA, there is also central sleep apnea, in which the respiratory muscles are not sufficiently activated. In this case , oxygen therapy may also be necessary to stabilize oxygen supply.
CPAP therapy: The standard treatment
CPAP therapy is considered the gold standard. Continuous positive airway pressure keeps the upper airways open, normalizing breathing and preventing nighttime oxygen desaturations. Many patients experience a significant improvement in sleep quality and increased energy levels in their daily lives as a result.
However, there are cases in which oxygen saturation remains low despite correctly applied CPAP therapy. In these cases, additional CPAP oxygen therapy can be helpful to maintain stable oxygen levels.
When additional oxygen is used
A combination therapy of CPAP and oxygen is appropriate in the following situations:
-
COPD-OSA overlap syndrome: Patients with chronic obstructive pulmonary disease and sleep apnea often have particularly low oxygen levels.
-
Persistent hypoxemia: If oxygen drops still occur despite CPAP, sleep apnea oxygen can help.
-
Central sleep apnea with hypoxemia: In cases of centrally caused breathing pauses, oxygen supplementation is often necessary.
-
Living at high altitudes: In regions with naturally lower oxygen levels, the combination makes sense.
Advantages and risks of combination therapy
The advantages of CPAP oxygen therapy are clear: more stable oxygen saturation, less strain on the heart and lungs, and more restful sleep.
However, there are also risks. Oxygen alone does not treat the underlying cause of sleep apnea – the narrowing of the airways. Furthermore, some patients may experience CO₂ retention. Therefore, close medical monitoring is essential.
Practical application: CPAP with oxygen
In practice, an oxygen concentrator is connected directly to the CPAP machine. This ensures a consistent supply of supplemental oxygen throughout the night. It is important to adhere to the oxygen flow rate prescribed by the doctor.
Safety aspects also play a role: oxygen is highly flammable, so devices such as candles or space heaters must be kept away. In addition, patients should regularly monitor their oxygen saturation using a pulse oximeter.
Why a VARON oxygen concentrator is ideal
A reliable oxygen concentrator is crucial for combination therapy. The VARON Serene 5L oxygen concentrator offers an ideal solution:
-
Powerful yet quiet: With a noise level of only 43 dB, it is barely noticeable even at night.
-
Continuous operation: Up to 72 hours of continuous supply are possible – ideal for CPAP use.
-
Precise oxygen supply: 0.5–5 L/min with a concentration of 93±3% ensures stable therapy.
-
User-friendly: LCD display, safety indicators and simple operation make everyday life easier.
-
Flexible: Thanks to its wheels, it can be easily moved between rooms.
In addition, VARON offers a convenient return option within 30 days and accessories such as filter sets or replacement cables to ensure that the devices always remain hygienic and functional.
The biggest advantage: VARON devices are also compatible with CPAP and BiPAP systems, making the combination of CPAP oxygen and sleep apnea oxygen safe and effective.
Patient comfort in everyday life
While most people already experience a feeling of constriction when wearing a mask during flu season, this is even more burdensome for COPD or sleep apnea patients. This is where portable devices like those from VARON demonstrate their strength: they are easy to use, quiet, and provide the necessary care without compromising quality of life.
Especially during flu season or colds, it's reassuring to be able to carry out the right therapy at home. Patients benefit from greater comfort and safety, which improves treatment adherence.
Key findings
-
CPAP oxygen therapy is the standard treatment for sleep apnea.
-
Oxygen is only added for sleep apnea if oxygen levels remain low despite CPAP.
-
VARON offers high-quality devices such as the Serene 5L, which are quiet, efficient and CPAP-compatible.
-
Patients can save money on their purchase with the code DC10 .
-
Medical supervision is crucial to ensure the correct adjustment of the therapy.
Conclusion
The combination of CPAP oxygen and sleep apnea oxygen is an effective approach for patients who continue to have low oxygen levels despite standard therapy. While CPAP keeps the airways open, the oxygen concentrator ensures a stable oxygen supply.
With a reliable device like the VARON Serene 5L, this therapy is not only safe but also comfortable. However, medical consultation is always necessary for the correct selection and settings. In this way, combination therapy can significantly improve quality of life and protect health in the long term.
