Spirometry in Mechanically Ventilated Chronic Obstructive Pulmonary Disease (COPD) Patients

Patients with COPD who deteriorate to Respiratory Failure pose a challenge to the intensivist both in ventilating an obstructed patient and in weaning from mechanical ventilation.

Currently there are no accepted extubation criteria in COPD patients that could predict successful weaning from mechanical ventilation. In this study we will attempt to correlate spirometric data to eventual weaning from mechanical ventilation.


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Spirometry in Mechanically Ventilated COPD Patients: Correlation of Lung Function Tests to Successful Weaning From Mechanical Ventilation

Further study details as provided by Assaf-Harofeh Medical Center:

Estimated Enrollment: 100
Study Start Date: September 2009
Estimated Study Completion Date: September 2012
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Detailed Description:
COPD patients who deteriorate to Respiratory Failure will be recruited. Sedation will be interrupted daily, and each day once the patient is awake and cooperative, spirometry will be performed. FEV1 and FVC will be recorded and later correlated to eventual rate of successful extubation.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
COPD patients with respiratory failure due to COPD exacerbation, and on mechanical ventilation

Inclusion Criteria:

  • >18
  • Mechanically ventilated due to COPD exacerbation

Exclusion Criteria:

  • decreased level of consciousness
