The mechanism of lung volume change during mechanical ventilation.

To understand ventilator-induced lung injury (VILI) during positive pressure ventilation, mechanisms of normal alveolar mechanics must first be established. Isotropic "balloonlike" alveolar volume (VA) change has been viewed as the prevailing mechanism of normal lung volume (VL) changes. We hypothesized that change in VL is predominantly caused by alveolar recruitment-derecruitment (R/D). Fifte...

Transient Mechanical Response of Lung Airway Tissue during Mechanical Ventilation

Patients with acute lung injury, airway and other pulmonary diseases often require Mechanical Ventilation (MV). Knowledge of the stress/strain environment in lung airway tissues is very important in order to avoid lung injuries for patients undergoing MV. Airway tissue strains responsible for stressing the lung's fiber network and rupturing the lung due to compliant airways are very difficult t...

Estimating lung volume during high frequency ventilation

The primary goals of lung ventilation are to bring oxygen into the alveoli from where it can enter the blood, and to eliminate carbon dioxide dissolved in the blood. Since CO2 is much more soluble in blood than oxygen, O2 transport is diffusion-limited and a large alveolar surface area is the primary factor controlling its delivery. CO2 transport is flow-limited, so that efficient gas transport...

Assessment of volume responsiveness during mechanical ventilation: recent advances

Predicting which patients with acute circulatory failure will respond to fl uid by a signifi cant increase in cardiac output is a daily challenge, in particular in the setting of the intensive care unit (ICU). Th is challenge has become even more crucial because evidence is growing that administering excessive amounts of fl uid is a risk factor in critically ill patients, in particular in patie...

Comparison of the effect of pressure support ventilation and volume assured pressure support ventilation on weaning patients off mechanical ventilation after cardiac surgery

Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...
