diaphragmatic breathing

diaphragmatic breathing /dī·əfragmat″ik/ [Gk, diaphragma, partition] , a pattern of expiration and inspiration in which most of the ventilatory work is done with the diaphragm. Many males normally breathe diaphragmatically, whereas few females do. The technique is taught to patients with chronic obstructive pulmonary disease to facilitate respiration. The patient is trained to strengthen the contractile force of the abdominal wall muscles to elevate the diaphragm and empty the lungs. The patient places a hand on the epigastrium during training to focus attention on that portion of the body. Also called diaphragmatic respiration. Compare abdominal breathing.
