Effects of Ventilation in Different Position on Hemodynamic Indexes in Acute Respiratory Distress Syndrome Patients

Objective To discuss and compare the effects of prone position and supine position on hemodynamic indexes in ARDS patients using machinenical ventilation. Method 220 cases of ARDS patients were randomly selected and divided into two groups: prone postion group and supine position group. Hemodynamic indexes were compared between the two groups when using machinenical ventilation. Results The PaCO2 and PaO2/FiO2 got better level in prone position group patients after 0. 5 and 1 hour of ventilation than in supine position group and also better level for PaO2 for 1 houre. Slight difference was detected for level of Hr after 1 hour and MAP after both 0. 5and 1 hour. The level of SV and SVV after 0. 5 hour were better in prone position group but the difference disappeared in 1hour's indexes. Conclusion Prone position showed better results for oxygenation function in patients of ARDS,slight effect on hemodynamic indexes. But it is still a new better choice for the ARDS patients and suggest clinical using.
