IntroductionPatients with chronic pulmonary obstructive disease (COPD) are at risk of acute exacerbation. Diaphragm muscle is classically highly solicited in COPD exacerbation.Patient ConcernsA COPD patient was admitted because of acute dyspnea with wheezing.Diagnosisacute COPD exacerbation.InterventionsA diaphragm ultrasound and a Doppler echocardiography were performed at bedside.OutcomesWe measured diaphragm thickening at the apposition zone and diaphragm inspiratory motion from the subcostal view, in addition with classical echocardiographic parameters.ConclusionDespite a normal diaphragm thickening, diaphragm motion during inspiration is reduced in acute COPD exacerbation. These apparently discrepant findings may be explained by the alterations of the respiratory mechanics during COPD exacerbations, which should be considered when evaluating the diaphragmatic function by imaging.
