Mechanical ventilation may have detrimental effects on the circulation and lungs and should be used appropriately.
A mode of ventilation refers to how the ventilator performs the work of the respiratory muscles. Common ventilatory modes include volume control, pressure control, and pressure support.
The goals of mechanical ventilation are to treat hypoxia and hypercapnia and to provide rest to the respiratory muscles.
Ventilator-associated lung injury should be minimized by avoiding volutrauma by limiting tidal volumes, barotrauma by limiting airway pressures, and atelectrauma by appropriate use of positive end expiratory pressure (PEEP).
A stepwise approach to assessment of respiratory failure and treatment by mechanical ventilation can help improve outcomes in critically ill patients.
