A-Flex technology utilizes Respironics patented Digital Auto-TrakTM Sensitivity to distinguish between exhalation and inhalation. During exhalation, A-Flex provides variable expiratory pressure relief that is the same as the clinically proven C-Flex technology. During inhalation, A-Flex also provides inspiratory comfort that varies with the patient's pressure level. The result is a pressure pattern that matches the patient's entire breathing cycle.
A-Flex is designed to work with Respironics clinically proven auto CPAP algorithm to improve
comfort even more by matching pressure delivery to your entire breathing
cycle. Like C-Flex, A-Flex provides flow-based pressure relief at the beginning of exhalation. Like Bi-Flex, A-Flex softens the pressure transition from inhalation to exhalation to provide additional comfort in an auto-CPAP mode. The pressure profile mirrors your breathing, and with the auto algorithm intelligence, it will respond to your therapeutic need throughout the sleep session.
