摘要
Mechanical ventilation provide important support organ function in critical ill patients. However, mechanical ventilation can produce many complications. Patients should be weaned from mechanical ventilation promptly. It is difficult to identify which patients are suitable for weaning, and studies show that 4%-23% of patients who have passed SBT can not be successfully weaning. There is many reasons for weaning failure. Cardiac function may play a key role. Brain natriuretic peptide(BNP) is a powerful biomarker for the diagnosis of heart failure. BNP has been shown to help determine whether weaning failure is caused by cardiovascular dysfunction.
