An interventional study of Programmed Weaning From Noninvasive Mechanical Ventilation in Acute Exacerbation of COPD, sponsored by Peking University Third Hospital. Active, not recruiting at 1 site in China. Open to participants aged 40 Years and older. Per ClinicalTrials.gov, last updated 2026-06-11.

Purpose of research:to explore a reasonable programmed withdrawal process of noninvasive ventilation and thereby reduce the duration of noninvasive mechanical ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease.
This is a single-center, prospective, randomized controlled study. The study subjects were patients with acute exacerbation of chronic obstructive pulmonary disease admitted to the intensive care unit, who were randomized into the study group, that is, the programmed withdrawal unit, and the control group was the traditional withdrawal unit (the attending physician decided the NIV regimen according to the condition). The primary study endpoints of the trial were complete evacuation of noninvasive ventilation (i. e. from the start of the patient to noninvasive ventilation) . Secondary study endpoints include length of stay in ICU, length of stay in hospital and failure of non-invasive ventilation (failure of non-invasive ventilation was defined as the patient underwent NIV again within 48 hours after being weaned off the ventilator;During NIV, endotracheal intubation was required, and invasive mechanical ventilation was used instead;The patient could not discontinue NIV completely and needed to use home non-invasive ventilation; The patient died.).
Peking University Third Hospital is the lead sponsor of 735 studies on the registry; 262 are open to participants now.

this is the traditional withdrawal unit (the attending physician will decide the NIV regimen according to the condition).
Programmed withdrawal unit: daily morning review arterial blood gas analysis (since the 2nd, daily morning stop non-invasive ventilation 1 hours, 2 hours, 3 hours, 4 hours after check arterial blood gas analysis), blood gas results suggest respiratory acidosis compensatory period (pH value greater than 7.35) can reduce daily noninvasive ventilation time, namely the noninvasive ventilation use time for 24 hours, 20 hours, the third day 16 hours, the fourth 12 hours, fifth day 8 hours. If ABG indicates still acid decompensation, continue the non-invasive ventilation regimen of the previous day. If noninvasive ventilation failed, invasive mechanical ventilation was performed.
Complete evacuation time of non-invasive ventilation
from the start of the patient to the absence of noninvasive ventilation or return to the level of normal ventilation time for patients with non-invasive ventilation on a home non-invasive ventilator before acute exacerbation
Time frame: At the end of non-invasive ventilation，through study completion, an average of 11 days
Time in the ICU
from the start of the patient stay in ICU to the day leave from ICU
Time frame: At the end of therapy in ICU，through study completion, an average of 14 days
length of stay
from the start of the patient stay in hospital to leave from hospital
Time frame: At the end of therapy in hospital, through study completion, an average of 20 days
Failure rate of non-invasive ventilation
failure of non-invasive ventilation is defined as a patient requiring endotracheal intubation to invasive ventilation or death
Time frame: At the end of therapy in hospital, an average of 20 days
