How does an automatic CPAP machine adjust pressure levels during sleep?:-An automatic CPAP machine adjusts pressure levels during sleep by continuously monitoring the user's breathing patterns. Using advanced algorithms, the machine detects changes in airflow indicative of airway obstruction or apnea events. It then responds in real-time by automatically adjusting the air pressure delivered to the airway, increasing or decreasing as needed to maintain optimal airflow and prevent disruptions in breathing, ensuring effective therapy throughout the night.
