Abstract:
A respiratory training apparatus for performing respiratory muscle training on a patient, comprising:a respiratory function valve for dynamically controlling a respiratory gas flow for a patient; a flow rate monitoring device positioned in a flow path of said respiratory gas, in fluidic communication with said valve, for measuring a flow rate of said respiratory gas; and a control unit electrically connected to said flow rate monitoring device, and said valve, and programmed to perform the steps of: receiving flow rate data from said flow rate monitoring device, dynamically determining patient lung volume data from said flow rate data at each of a plurality of patient lung volumes in a breathing cycle, selecting a plurality of predetermined respiratory training resistive load patterns to be applied to said patient, each respiratory training resistive load pattern defining a plurality of respiratory training resistive loads each to be applied at a patient lung volume value said plurality of resistive loads including a maximal resistive load, a minimal resistive load, and at least one intermediate resistive load higher than said minimal resistive load and lower than said maximal resistive load, and for dynamically controlling said valve to apply said plurality of respiratory training resistive load patterns to said respiratory gas flow according to said lung volume data.
