Mechanical ventilation
Mechanical ventilation supports gas exchange by moving gas into and out of the lungs under controlled pressure or volume conditions. It can also cause injury and requires individualized monitoring.

Pressure and volume
Tidal volume, respiratory-system compliance and resistance interact with airway pressures; measured airway pressure is not identical to transpulmonary pressure.
Oxygenation and ventilation
Inspired oxygen concentration and end-expiratory pressure influence oxygenation, while effective alveolar ventilation helps regulate carbon dioxide.
Patient–ventilator interaction
Sedation, spontaneous breathing, trigger settings and patient physiology alter the delivered breath and total respiratory workload.
Lung protection
Overdistension, repetitive collapse and hemodynamic effects are important hazards; specific settings require disease-specific protocols and bedside expertise.
