Incidence, Risk Factors and Outcomes of Diaphragm Dysfunction After Lung Transplantation

Sonographic measurements (diaphragm, abdominal muscle, and quadriceps thickness) will be acquired when listed for lung transplantation. Sonographic measurements will be recorded on a daily basis for up to 1 week after transplantation (while the patient remains intubated).

Maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP) will be acquired after listing for lung transplantation. After transplant, MIP will be recorded once patients are eligible for a trial of spontaneous breathing and weekly thereafter. MEP will also be recorded at ICU discharge.
