Home spirometry

A less controversial method of monitoring allograft function is patient-administered home spirometry. Once postoperative function has been stabilized, the forced expiratory volume in one second (FEVj) and forced vital capacity (FVC) should vary less than 5% from the baseline FEVj and FVC right after transplantation (Bjortuft et al. 1993 Morlion et al. 2002). A decline of 10% or more in spirometric values that persists for more than 2 days has been reported to indicate either rejection or infection.
