Abstract
This disclosure provides a breathing recognition method applicable in a ventilation apparatus. In the breathing recognition method, an airway pressure and a gas flow rate can be acquired during mechanical ventilation; correlation data corresponding to the airway pressure and the gas flow rate can be determined according to the airway pressure and the gas flow rate; and a breathing state of a patient can be recognized according to a change in the correlation data.
