[Methods in mixed ventilation: advantages, disadvantages and consequences for work of breathing].
During partial ventilatory support modes both the ventilator and the patient are performing mechanical work. These modes are currently used as mechanical ventilatory support to provide a better synchronism between the patient and the machine and to avoid a complete rest of the respiratory muscles, or as modes of weaning from mechanical ventilation. ⋯ Lastly, during inspiratory pressure support, each spontaneous cycle is assisted by pressurization of the circuit. This latter modality alone seems efficiently to decrease the patients' breathing work while allowing complete synchronism between patient and ventilator.
