Objective This study aimed to assess diaphragmatic mobility by chest ultrasonography and echocardiographic changes in mechanically ventilated chronic obstructive pulmonary disease patients on different modes of mechanical ventilation. Patients and methods The present study was carried out on 50 mechanically ventilated chronic obstructive pulmonary disease patients. Chest ultrasonography for the assessment of diaphragmatic mobility in addition to echocardiography was performed on different modes of mechanical ventilation in the same session at any time since mechanical ventilation. Results There was a highly statistically significant relation between diaphragmatic excursion and different modes of mechanical ventilation, where excursion increased significantly, with its peak at pressure-support ventilation (PSV). In terms of diaphragmatic thickness, the thickness of diaphragm decreased significantly at PSV. No significant correlation was detected between echocardiography in Ejection fraction, right ventricular systolic pressure, tricuspid annular plane systolic excursion, and different modes of mechanical ventilation. Conclusion The best diaphragmatic mobility was on PSV, which improved lung volumes and ventilation, and may accelerate the weaning process. In addition, we concluded that the echocardiographic finding was not affected by different modes of mechanical ventilation.
