Abstract

Exemplary embodiments provide a respiratory device that can perform mechanical ventilation and/or inexsufflation. The respiratory device can include a mechanical medical ventilator, a sensor, a display and a processor. The mechanical medical ventilator assists a patient with the respiratory cycle. The sensor can measure an intra-thoracic respiratory parameter during the respiratory cycle. The display can display a graphical representation that dynamically depicts at least one of a patient'"'"'s lung or thorax based on the intra-thoracic respiratory parameter in real-time during the respiratory cycle. The processor can update the graphical representation on the display in real-time based on the respiratory parameter. The processor updates the graphical representation to depict at least one of an expansion or a contraction of at least one of the lung or thorax during the respiratory cycle.
