摘要
Disclosed is a method for controlling the slope rise time in a PCV ventilation mode of a turbine anaesthesia apparatus, comprising: setting one quarter of the set slope rise time (Tslope) as an e-exponential function time constant; determining a control pressure value (Praise) according to the e-exponential function time constant; and increasing the turbine pressure according to the set control pressure value (Praise). Under the control of the control method, the turbine pressure rises quickly during the initial stage, but is smooth when approaching and reaching a target pressure (PTarget). Such a control method facilitates sufficient gas exchange between the patient's pulmonary alveoli and fresh air, so as to achieve a good effect.
