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.

Original schematic relationship map for this topic; relationships are organized for study, not intended as an anatomical depiction or a diagnostic algorithm.

Concept 01

Pressure and volume

Tidal volume, respiratory-system compliance and resistance interact with airway pressures; measured airway pressure is not identical to transpulmonary pressure.

Concept 02

Oxygenation and ventilation

Inspired oxygen concentration and end-expiratory pressure influence oxygenation, while effective alveolar ventilation helps regulate carbon dioxide.

Concept 03

Patient–ventilator interaction

Sedation, spontaneous breathing, trigger settings and patient physiology alter the delivered breath and total respiratory workload.

Concept 04

Lung protection

Overdistension, repetitive collapse and hemodynamic effects are important hazards; specific settings require disease-specific protocols and bedside expertise.

Education / safety note: This is not a ventilator setup guide or a source of settings for a real patient; critical care interventions require qualified teams.
