Abstract: A high-flow respiratory therapy system includes a blender arranged to receive a first gas and a second gas and to output a combination thereof as a delivered gas to a patient respiratory interface, an airflow source for providing a flow of air to the blender as the first gas, a valve operable to provide oxygen gas from an oxygen gas source to the blender as the second gas, a heater operable to heat the delivered gas at the patient respiratory interface, a pulse oximeter, and a controller configured to execute a learning procedure in response to a trigger. The learning procedure may include varying a parameter of the airflow source, a parameter of the valve, and a parameter of the heater and determining a recommended parameter based on one or more measurements of the pulse oximeter. The controller may output a recommendation to adjust the recommended parameter.

Abstract: An apparatus for applying positive pressure nebulized liquid to a patient includes a funneled T-connector having a funnel with a first opening of a first diameter, a second opening of a second diameter smaller than the first diameter, and a funnel wall extending between the first and second openings. The funneled T-connector further has a cylindrical nebulizer port that extends outwardly from the funnel wall. A nebulizer cup assembly includes a nebulizer cup to contain liquid and a nebulizer cap to removably attach to a top region of the nebulizer cup. The nebulizer cap has a cylindrical nebulizer outlet sized to removably attach to the cylindrical nebulizer port. The cylindrical nebulizer outlet extends upwardly through the nebulizer passage, beyond the cylindrical nebulizer port, and into the internal funnel space such that a top edge of the cylindrical nebulizer outlet is located within the internal funnel space.
