When it comes to obstructive sleep apnea, continuous positive airway pressure (CPAP) therapy is the gold standard and typically the first line of treatment. CPAP delivers pressurized air to the airway, which helps keep the airway open and reduces instances of disturbed breathing. When CPAP therapy works, the patient immediately feels relief. However, in some cases, the patient may struggle to adapt to CPAP therapy. For patients with positional obstructive sleep apnea (POSA)—roughly 36-47% of patients with OSA—a new sleep position therapy device called NightBalance Lunoa may be the answer.
