Thus, each participant underwent one evaluation in the decompensated phase (V1) and two in the compensated phase (V2, V3) of their disease.The evaluation protocolHR and Ox were considered time series with a sample frequency of 1 Hz and were collected throughout the evaluation with a pulse oximeter (Model 3100, brand Nonin® Medical, Inc., Plymouth, MN, USA) placed on the left index finger.
