Wearable Devices to Assess Physiological Parameters in Lung Transplant Patients

The present study will be a prospective non-interventional study involving 15 to 20 lung transplant patients. The patient will do as usual Forced Expiratory Volume (FEV1) measures and some physiological parameters will be automatically recorded through the wearable and wireless sensors. The spirometer will also be connected but only to transmit stored data, not for real time use. The patient and the physician will not have access to the data until the end of the study. The 6 following physiological parameters will be recorded: heart rate, respiratory rate, body temperature, SPO2, motion, and sleep. The study duration for each patient will be 6 months. The primary endpoint will be the number of FEV1 measures combined with physiological parameters. This primary endpoint has been chosen because it is easy to obtain. The secondary endpoints will be: - physiological parameters associated with a 10% or higher decrease in FEV1, - correlation between variations of physiological parameters and occurrence of a clinical event (defined by presumption of infection or of graft failure), - interval between the first significant modification of each physiological parameter and the onset of an event, - number of recorded values, - patient's satisfaction. In this pilot phase, there is no real time health advice.
