1. A diaphragm measurement device, comprising:
at least one electronic processor programmed to perform a diaphragm measurement method including:
receiving ultrasound imaging data of a dimension of a diaphragm of a patient during inspiration and expiration while the patient undergoes mechanical ventilation therapy with an associated mechanical ventilator;
receiving respiratory data of the patient during inspiration and expiration while the patient undergoes the mechanical ventilation therapy;
calculating a diaphragm thickness metric based on the received ultrasound imaging data of the diaphragm of the patient and the received respiratory data;
displaying, on a display device, a representation of the calculated diaphragm thickness metric; and
controlling the associated mechanical ventilator to adjust one or more parameters of the mechanical ventilation therapy delivered to the patient based on the calculated diaphragm thickness metric;
wherein the respiratory data of the patient comprises one of an airway pressure or airway flow in an airway of the patient, and the at least one electronic processor is further programmed to calculate the diaphragm thickness metric based on the airway pressure or the airway flow; and
wherein the respiratory data comprises a mean airway pressure value or a mean airway flow value at an end of inspiration and at an end of expiration.
