Abstract
A major goal of critical care clinicians should be to liberate patients from mechanical ventilation as early as possible to avoid a lot of complications and risks associated with prolonged mechanical ventilation, including ventilator induced lung injury, ventilator associated pneumonia, increased length of ICU and hospital stay.
Assessing readiness for liberation from mechanical ventilation is the first step in the process of liberation, and begins with the resolution of respiratory failure and/or the events that promoted the need for mechanical ventilation.
The use of standardized protocols to wean patients from mechanical ventilation gives better results. Such protocols are used to systematically evaluate patients receiving mechanical ventilation to assess their potential ability to be removed from mechanical support.
Failure to wean is often due to multiple factors and clinician should comprehensively look for ways to correct each abnormality and improve clinical status. Weaning failures are usually due to incomplete resolution of the illness that precipitated the need for mechanical ventilation or, due to the development of a new problem. Weaning from mechanical ventilation depends on the strength of the respiratory muscles, load applied to the muscles and the central drive.
Rehabilitation is the process of restoring health or normal life by training and therapy after illness. Rehabilitation efforts have focused on improving muscle power and endurance through passive and active movements, posture and different forms of exercise.
