Abstract

The aim of the study was to evaluate feasibility of respiratory biofeedback (RB) in patients undergoing CABG surgery during hospital stay. Before CABG surgery all patients (n = 93, aged 40 to 77 years) were divided into three groups after performing capnography and trial course of RB. The first group consisted of patients who agreed to get psychological support (PSY group, 26.9 %), and the second group were patients who accepted RB with psychological support (RB group, 21.5 %). There were breathing frequency reduction and expiratory time increment in the RB group only. The RB group demonstrated a shorter length of postoperative hospital stay (mean 9.5 [SE 1.0] days) than the usual care group (13.9 [0.7]) and the PSY group (12.4 [0.8]).

Key words
