Echocardiographic Measures of Diastolic Function Are Preload Dependent during Triggered Positive Pressure Ventilation: A Controlled Crossover Study in Healthy Subjects
Figure 2
Effects of on- and off-loading during spontaneous respiration. Echocardiographic indices of diastolic function with subjects placed in varying positions during spontaneous respiration. : peak early diastolic velocity of the lateral mitral annulus. : peak early transmitral flow. : peak atrial transmitral flow. : deceleration time of . Data are presented as median, interquartile range (box) and range (whiskers). Graphs show independency of to preload, whereas , , , and vary according to positioning.
