对 18 名接受成人呼吸窘迫综合征 (ARDS) 呼吸治疗的患者进行床边热稀释法测量右心室射血分数和容量。将这些测量值与二维超声心动图同时获得的右心室尺寸进行比较。热稀释法测得的右心室射血分数与二维超声心动图面积收缩分数之间存在显着相关性（r = 0.74；P < 0.001），热稀释法测得的右心室舒张末期容积与二维超声心动图舒张末期面积之间存在显着相关性（r = 0.70；P < 0.001），热稀释法测得的右心室收缩末期容积与二维超声心动图测得的收缩末期容积之间存在显着相关性。二维超声心动图收缩末期面积（r = 0.78；P < 0.001）。右心室舒张末期压力是右心室前负荷的常用指标，与二维超声心动图舒张末期面积不相关。热稀释方法可以在危重患者的床边可靠地测量右心室射血分数和容量。通过这种方法评估右心室舒张末期容积似乎比压力测量更能预测右心室前负荷。
Measurements of right ventricular ejection fraction and volumes were obtained at bedside by the thermodilution method performed with a fast-response balloon-tipped thermistor in a group of 18 patients undergoing respiratory therapy for the adult respiratory distress syndrome (ARDS). These measurements were compared with right ventricular dimensions simultaneously obtained with 2-dimensional echocardiography. A significantly correlation was found between right ventricular ejection fraction by thermodilution and 2-dimensional echocardiographic fractional area contraction (r = 0.74; P < 0.001), between right ventricular end-diastolic volume by thermodilution and 2-dimensional echocardiographic end-diastolic area (r = 0.70; P < 0.001), and between right ventricular end-systolic volume by thermodilution and 2-dimensional echocardiographic end-systolic area (r = 0.78; P < 0.001). Right ventricular end-diastolic pressure, a commonly used index of right ventricular preload, did not correlate with 2-dimensional echocardiographic end-diastolic area. The thermodilution method allowed reliable measurements of right ventricular ejection fraction and volumes at bedside in critically ill patients. Appraisal of right ventricular end-diastolic volume by this method appeared to be a better predictor of right ventricular preload than were the measurments of pressure.
