The initial period during which a CPAP machine operates at a lower pressure than the prescribed therapeutic pressure is known as its period of gradual pressure increase. This lower pressure makes it easier to fall asleep, especially for new users or those sensitive to the immediate sensation of pressurized air. Once asleep, the device gradually increases the air pressure over a pre-determined period until it reaches the prescribed level for optimal therapy.
This gradual pressure increase offers several advantages. It enhances comfort and reduces feelings of claustrophobia sometimes associated with starting CPAP therapy at full pressure. Additionally, it can minimize certain side effects, such as dry nose and throat, by allowing the user to acclimate to the airflow. This feature has become a standard component of modern CPAP devices, contributing significantly to increased patient compliance and acceptance of this vital therapy for sleep-related breathing disorders.
