Alveolar mechanics at the bedside

Mechanical power has recently emerged as an important indicator of ventilator lung injury, and mortality. Most studies have focused on the whole respiratory system mechanical power, and few have studied the trans-pulmonary mechanical power. A newer calculation highlighted the concept of alveolar mechanics and mechanical power. In this brief review, we illustrate the various types and different calculations of the respiratory system, lung, and alveolar mechanical power.
