BACKGROUND Lateral turning of critical care patients receiving mechanical ventilation can adversely affect hemodynamic status. OBJECTIVE To study hemodynamic responses to lateral turning. METHOD A time-series design with automated signal processing and ensemble averaging was used to evaluate changes in heart rate, mean arterial pressure, and pulse pressure due to lateral turning in 13 adult...
