Introduction: diaphragmatic excursion by ultrasound is a tool that allows to properly assess the patient with critical pathology of the airway, with pleural effusion and neurovascular injuries that generate restrictive patterns on the chest. Performing dynamic evaluation of the diaphragm before and after a procedure allows us to know the changes in the natural history of the disease. For this reason, it is essential to know the normal values of the study population, and how it interferes with the other anthropometric variables of the patients. Materials and methods: analytical prevalence study for the measurement of normal excursion variables and the correlation with anthropometric variables of patients without pulmonary or diaphragmatic pathology. Results: simple random sample of 50 diaphragms with a distribution of 68% of women, with a mean age of 39 years and a median of the abdominal perimeter of 78 cm. The thickness of the diaphragm was 3.4 mm on inspiration and 2.6 mm on expiration, with a mean diaphragmatic excursion of 15 mm. The Kendall correlation between the excursion and the anthropometric variables had a value of rho = 0.94. Conclusions: the normal values of the diaphragmatic excursion are highly variable according to the population studied, with a clinical relationship between the anthropometric variables. This allows us to recommend that we should always perform a dynamic assessment of the diaphragm before and after each procedure in order to evaluate significant changes in diaphragmatic excursion values.
