Statistics of complications in patients with unplanned re-intubation.

Complication type	Incidence rate (%)	Description of complication	Impact on patients
Pulmonary infection	5.12	Disruption of respiratory tract defense mechanism due to intubation, allowing easy bacterial invasion	Increases rehabilitation difficulty, may lead to respiratory failure or sepsis
Respiratory failure	7.18	Often secondary to pulmonary infection, manifesting as decreased respiratory function	Reliance on ventilator, affects quality of life, may threaten life
Cardiovascular events	10.23	Includes arrhythmias, myocardial infarction, etc.	Increases patient discomfort, may lead to heart failure
Other infections	11.21	Such as urinary tract infection, wound infection, etc.	Prolongs recovery time, increases treatment costs
Gastrointestinal bleeding	4.79	Associated with stress response and drug side effects	Can lead to anemia and malnutrition
