Monitoring Mechanics During Mechanical Ventilation

Abstract

Patients with acute respiratory failure necessitating mechanical ventilation have significant abnormalities in pulmonary mechanics, yet formal assessment of their nature is rarely included in clinical decision making. Because of our increased understanding of the pathophysiology, together with the rapid, technological advances, assessment of respiratory mechanics-resistance, compliance, and work of breathing-can be safely and rapidly performed in the intensive care unit (ICU). This chapter provides a review of abnormalities in respiratory mechanics that can be monitored during passive and spontaneous breathing, a description of the methods and techniques, and a summary of clinical observations and applications in critically ill patients.
