Will 2 liters of oxygen through CPap injure eyes?

Using 2 liters of oxygen through CPAP (continuous positive airway pressure) therapy is generally considered safe and does not pose a significant risk of eye injury. CPAP therapy involves delivering pressurized air to the lungs through a mask worn over the nose and mouth to help individuals with sleep apnea breathe more easily. The amount of oxygen delivered during CPAP therapy is typically prescribed by a healthcare professional based on the individual's specific needs and medical condition.

While dry eyes or mild eye irritation can sometimes occur, especially if the CPAP mask does not fit properly or if the airflow is directed toward the eyes, these issues are usually temporary and can be managed by adjusting the mask or using saline eye drops.

If you are experiencing severe eye pain, blurred vision, or other unusual eye symptoms while using CPAP therapy, it is essential to consult with a healthcare professional, such as an eye doctor or respiratory specialist, for proper evaluation and management. They can assess your condition, provide further guidance, and make any necessary adjustments to your CPAP settings or mask to ensure safe and comfortable use.
