Dynamic Hyperinflation In Mechanically Ventilated Chronic Obstructive Pulmonary Disease Patients

Evaluation Of Dynamic Hyperinflation In Mechanically Ventilated Chronic Obstructive Pulmonary Disease Patients

Chronic obstructive pulmonary disease is a common respiratory condition that is characterized by inflammation of the large and small peripheral airways , the alveoli and adjacent capillary networks. Severe airflow obstruction that imposes a significant load on the respiratory system is a major manifestation of Chronic obstructive pulmonary disease. The reduced expiratory airflow also causes air trapping at the end of expiration , producing alveolar pressure that are higher than atmospheric pressure before the next breath. This condition is intrinsic positive end-expiratory pressure .

Inclusion Criteria:

• patient with acute exacerbation of Chronic obstructive pulmonary disease and respiratory failure who are intubated and mechanically ventilated.

Exclusion Criteria:

• patient with neuromuscular diseases.
• patient with pulmonary vascular diseases e.g pulmonary embolism.
