A recently granted patent (Publication Number: US11883594B2) discloses a respiratory system designed to deliver respiratory therapy to patients while also providing crucial patient-related information. The system includes a respiratory device that delivers nasal high flow therapy and is equipped with a controller. This controller receives measurements of flow parameters and performance data, determines the validity of assumed effects on these parameters, and uses validated data to estimate the patient's respiratory rate. Additionally, the controller can assess whether the patient is wearing the system's interface, enhancing the system's monitoring capabilities.

Furthermore, the respiratory device in the system includes a blower with a motor, where the motor speed serves as a key parameter. The controller evaluates the motor speed to ensure the assumed effects are valid, with thresholds set for motor speed changes. The system can also incorporate supplementary gases like oxygen, with the controller monitoring the gas composition and flow rate. By analyzing validated data and performing frequency analysis, the controller accurately estimates the patient's respiratory rate. Additionally, the system features a non-sealed interface, providing flexibility and comfort for the patient during therapy sessions. Overall, this patented respiratory system offers advanced monitoring and therapy delivery capabilities, enhancing patient care and treatment outcomes.
