  • Effects of Lateral Position Ventilation on Lung Volume and Oxygenation in Patients with Acute Respiratory Distress Syndrome

    Objective To explore the effects of lateral position ventilation on lung volume and oxygenation in patients with acute respiratory distress syndrome ( ARDS) . Methods Fourteen patients with ARDS were enrolled. Supine position, lateral position and supine position were successively adopted and continued for one hour respectively. End-expiratory lung volume ( EELV) was measured at the end of each epoch. Effects of different position on gas exchange, lung mechanics and hemodynamics were monitored.Results EELV was increased from ( 1109 ±321) mL to ( 1376 ±381) mL after lateral ventilation ( P lt;0. 05) , and decreased to ( 1143 ±376) mL after the second supine ventilation ( P lt;0. 05) . Compared with initial supine ventilation, there was no significant difference in EELV after the second supine ventilation( P gt;0. 05) . PaO2 /FiO2 was increased from ( 154. 3 ±35. 0) mm Hg to ( 189. 9 ±60. 1) mm Hg after lateral ventilation ( P lt;0. 05) , and increased to ( 209. 2 ±75. 4) mm Hg after the second supine ventilation ( P lt; 0. 05) . Compared with initial supine ventilation, PaO2 /FiO2 was increased greatly after the secondsupine ventilation ( P lt; 0. 01) . There was no significant difference in PaCO2 , lung mechanics and hemodynamics after changing different position. Conclusion Lateral position ventilation can increase EELV and improve oxygenation in patients with ARDS.
