Abstract:
A control method for a ventilator having a sputum excretion function, and a ventilator. The control method for a ventilator having a sputum excretion function comprises: when a ventilator operates in a respiratory operation mode, controlling a first input end of an air path switching apparatus (10) to come into communication with an output end thereof, so as to output a first air flow to a respiratory pipeline to assist in human respiration (S100); and when the ventilator operates in an expectoration operation mode, controlling the first input end and a second input end of the air path switching apparatus (10) to alternately come into communication with the output end thereof, so as to alternately output the first air flow and a second air flow to the respiratory pipeline, so that positive-negative alternating ventilation for humans is realized, thereby assisting in human expectoration (S200).
