Abstrakt		The aim of the study was to find out if functional electrical stimulation of abdominal muscles (FESAM) could maintain pulmonary ventilation at clinically acceptable level in patients with spinal cord injury (SCI). Two patients with complete spinal cord injury (C0 and C2level) aged 19 (Cw) and 25 (EF) years, on mechanical ventilation for 7 to 12 months, unable to breath spontaneously, were tested. FESAM was performed with custom-made, battery powered, four-channel stimulator via eight self-adhesive electrodes, sited symmetrically on the trunk in order to stimulate mm. recti abdominis (RA) and lateral group of abdominal muscles (LA). Stimulation was performed in sitting position. Parameters of stimulation: amplitude of stimulus 60-100 mA, stimulation frequency 45 Hz, pulse train duration of 1 sec., breathing frequency of FES artifically activated 20 breaths/min. Volumes were measured with pneumotachograph. Oxygenation was controlled with pulse oximeter. The limit level of oxygen saturation was 0.92. The following mean values of tidal volume were achieved in patient CW during one minute of FESAM:RA-362 m, LA-577 ml, RA+LA-816 ml. The average mean value during three minutes of FESAM RA + LA was 513 ml. FESAM of RA + LA in EF patient resulted in 321 ml of tidal volume. The values of tidal volume measured during FESAM in SCI patients were sufficient to maintain adequate oxygenation during few minutes of duration of stimulation. The results indicate clinical potentials of newly developed FESAM supported ventilation.
