To investigate the effect of positive and negative pressure extubation on mechanical ventilation patients in the intensive care unit (ICU). A prospective randomized controlled study was performed, 105 ICU patients who successfully passed the spontaneous breathing test (SBT) after mechanical ventilation of Nanjing Jiangbei Hospital Affiliated to Nantong University from January 2019 to March 2021 were enrolled. According to random number table method, they were randomly divided into positive pressure extubation group (53 cases) and negative pressure extubation group (52 cases). During extubation, all patients were placed in semi-decubitus position (raising the head of bed at an angle range from 30 degree angle- 45 degree angle), the secretions from mouth, nose, throat and trachea were removed. In the negative pressure extubation group, the sputum suction tube was inserted into the tracheal tube and passed over the distal opening to carry out continuous negative pressure suction in the tracheal tube after discon
