This study objective was to determine whether passive cycling leg movement increases hemodynamic and metabolic variables in sedated mechanical ventilation dependent patients. METHODS: Five sedated mechanical ventilation dependent patients in a 18-bed intensive care unit of a university hospital were evaluated. Passive cycling leg movements were performed for 10min at a 30 movements/min rate. Complete hemodynamical data were recorded and arterial and mixed venous blood sample were collected 5 minutes before and after 5 minutes after the maneuver completion. RESULTS: All patients had increased oxygen consumption (VO2). The VO2 increase occurred with a concomitant drop in mixed venous blood saturation (SvO2), likely from both oxygen extraction ratio (O2ER) and cardiac index (CI) increase. CONCLUSION: passive cycling leg movements may influence hemodynamical and metabolic status in sedated mechanical ventilation-dependent patients.
