    • An apparatus is described (1) for measuring the blood flow (Vb) between the trunk and the extremities. Such an apparatus (1) comprises a whole body plethysmograph (102; 4, 12, 15, 40) for measuring the variations of gas volume in the lungs (ΔVL), a thoraco-abdominal plethysmograph (101, 2, 3) for measuring the volume variations of the trunk (ΔVCW) and a system for processing (20) allowing measurement of the said variations of gas volume of the lungs (ΔVL) and the volume variations of the trunk (ΔVCW) so as to compute the volume of blood shifted between the trunk and the extremities (Vb). Further a process is described for measuring the volume of blood shifted between the trunk and the extremities (Vb). Such a process comprises: a measurement (121) of the volume variations of the trunk (ΔVCW) by means of thoraco-abdominal plethysmography, a measurement (104) (performed at the same time as the previous measurement) of the variations of gas volume of the lungs (ΔVL) by means of whole body plethysmography; a processing (120) of said volume variations of the trunk (ΔVCW) and of said volume variations of the lungs in order to measure the volume of blood shifted between the trunk and the extremities (Vb).
    • 描述了用于测量躯干和四肢之间的血流量(Vb)的装置(1)。 这种装置(1)包括用于测量肺中的气体体积变化(DeltaVL)的全身体积描记器(102; 4,12,15,40),用于测量的胸腹部体积描记器(101,2,3) 躯体的体积变化(DeltaVCW)和用于处理(20)的系统允许测量所述肺的气体体积变化(DeltaVL)和躯干的体积变化(DeltaVCW),以便计算血液的体积 在躯干和四肢之间移动(Vb)。 此外,描述了用于测量在躯干和四肢之间移位的血液的体积(Vb)的过程。 这样的方法包括:通过胸腹部体积描记法测量(123)体积变化(DeltaVCW),测量(104)(与之前的测量同时进行)气体体积变化 的肺(DeltaVL)通过全身体积描记术; 所述躯干(DeltaVCW)的体积变化和所述肺的体积变化的处理(120)是为了测量在躯干和四肢(Vb)之间移位的血液的体积。
