THERAPEUTIC CLASS
Mechanical Ventilation: Settings and Basic Modes
Mechanical ventilation is a lifesaving tool utilized in the intensive care unit, during surgical procedures
requiring general anesthesia, and in long-term acute care settings to assist patients who require additional
respiratory support. Invasive mechanical ventilation requires an endotracheal tube that is connected to a
ventilator, whereas non-invasive ventilation delivers oxygen through a face mask. Both types can be used for
acute or chronic hypoxemic or hypercarbic respiratory failure, which is defined as insufficient oxygenation,
insufficient alveolar ventilation, or both. Invasive mechanical ventilation is also useful for those who require
airway protection to reduce the risk of aspiration (e.g., depressed mental status from an overdose or brain injury) as well as in the operating room during procedures requiring general anesthesia
