Both supplemental oxygen and CPAP therapy can cause side effects, such as dry nasal passages and facial irritation from wearing a mask. Oxygen therapy can sometimes cause issues similar to sleep apnea symptoms, such as daytime sleepiness and morning headaches.
Finding the right accessories can help alleviate common side effects of combining CPAP and oxygen therapies. A heated humidifier, for example, adds moisture to the pressurized air and may help relieve sinus irritation. Choosing the right face mask can also help prevent skin irritation, mask leaks, and other common problems.
