ABSTRACT:
The present inventions provide respiratory therapy apparatus that introduce water into the pressurized air delivered to a user during various positive airway pressure therapies and corresponding methods. The respiratory therapy apparatus may be configured to administer one or more positive airway pressure therapies, including: continuous positive airway pressure therapy (CPAP), bi-level positive airway pressure therapy (BPAP), auto positive airway pressure therapy (autoPAP), proportional positive airway pressure therapy (PPAP), and/or other positive airway pressure therapies. The respiratory therapy apparatus may include a user interface that defines an interface passage to communicate pressurized air to the user for inhalation and a humidifier that introduces water into the pressurized air generally at the interface passage. Methods according to the present inventions may include introducing water into the interface passage at one or more humidifier ports disposed about the interface passage.
