Volume-controlled ventilation modes: In volume-controlled ventilation, the pre-set tidal volume is applied regardless of airway resistance or lung compliance. Ventilation pressures depend on the current resistance and compliance.
Pressure-controlled ventilation modes: In pressure-controlled ventilation, the inspiratory pressure (Pinsp) is kept constant. The applied tidal volume depends on compliance.
Spontaneous ventilation modes: In patients unable to sustain unassisted breathing, spontaneous ventilation modes can support spontaneous breathing by keeping the alveoli open., or by reducing the patient´s increased work of breathing.
Hybrid ventilation modes: As a further development of pressure-control ventilation, hybrid ventilation modes combine the known advantages of pressure-controlled ventilation forms with those of volume-constant ventilation. The users define a safe window with the settings parameters, in which the pressure levels can automatically adjust to the respective changes in the patient´s lung.
Closed-loop ventilation modes: The term ´closed loop´ refers to a group of ventilation modes which use complex algorithms or different variables. These allow ventilatory support to adjust automatically in line with the patient´s needs.
