    [Abstract]Objective：To investigate the the application efect of invasive mechanical ventilation with high positiveend expiratory pressure (PEEP)combined with closed sputum aspiration in patients with acute cardiogenic pulmonary edema.Method： A total of 160 patients with acute cardiogenic pulmonary edema underwent invasive mechanicalventilation treated in theFirst People'sHospital of Qinzhou from May 2022 to June 2024 weredivided into group A (given high PEEP combined with closed sputum aspiration)，group B (given high PEEP combined with open sputum aspiration)， group C (given low PEEP combined with closed sputum aspiration) and group D(given low PEEP combined withopen sputum aspiration)according tothe random number table method， with 40cases in each group.The total effective rate， mechanical ventilation time ......
