Objective: Measurement of loop gain in patients with obstructive sleep apnea (OSA) is of great importance for determining the cause of OSA and realizing precision medicine. In this study, automatic measurement of loop gain is carried out during wakefulness based on the pseudorandom binary sequence (PRBS) CO stimulation method.
Methods: A respiratory data acquisition platform is designed and constructed to automate the processes of gas configuration, ventilatory stimulation with CO and data acquisition.
