Abstract
To understand the impact of respiratory mechanics during mechanical ventilation, it is helpful to partition between the lungs and the chest wall. Esophageal pressure (Pes) is used to calculate chest wall compliance. However, esophageal pressure is not always used in the clinical arena. The value of chest wall compliance has been proposed to be estimated using 4% of the predicted value of vital capacity (VC) [1].
Highlights
To understand the impact of respiratory mechanics during mechanical ventilation, it is helpful to partition between the lungs and the chest wall
We measured other ventilator parameters that were used for chest wall compliance (Ccw-measured)
We used an equation to calculate the predicted vital capacity (VC) according to gender, age, and height [2]: 4% of the predicted VC was used as the value for predicted chest wall compliance (Ccw-predicted)
Summary
This study compared the difference between the predicted and the measured value of chest wall compliance in patients with ARDS.
