Diaphragm ultrasonography is used to identify causes of diaphragm dysfunction. However, its correlation with pulmonary function tests, including maximal inspiratory (MIP) and expiratory pressures (MEP), remains unclear. This study investigated this relationship by measuring thickness, thickening fraction (TF), excursion (DE) using ultrasonography, their MIP MEP. It also examined the influence age, sex, height, BMI on these measures.
