Claim 3:
4. The method for determining the flow of the positive pressure ventilation therapy machine according to claim 3, wherein the step of determining the current gas flow output by the positive pressure ventilation therapy machine by adopting linear relation fitting when the current pressure value is not found in the preset list comprises:
finding two relational expressions corresponding to two pressure values adjacent to the current pressure value in the preset list and determining the two relational expressions as a first relational expression and a second relational expression when the current pressure value is not found in the preset list;
determining a first gas flow and a second gas flow according to the current operating parameter, the first relational expression and the second relational expression; and
determining a mean value of the first gas flow and the second gas flow as the current gas flow output by the positive pressure ventilation therapy machine.
