已在 12 只具有完整循环反射的开胸狗和 14 只开胸无反射狗中确定了正常静脉回流曲线。这些曲线表明，当右心房压力降至 -2 至 -4 mm Hg 时，静脉回流达到最大值，并在负压无限低时保持该最大值。当右心房压力上升至正值时，静脉回流下降，并在右心房压力上升至等于平均循环压力时达到零。根据这些研究和之前测量完整狗静脉回流曲线上各个点的研究，初步制定了正常完整狗的静脉回流曲线。
The normal venous return curve has been determined in 12 open-chest dogs with intact circulatory reflexes and in 14 open-chest areflex dogs. These curves show that venous return reaches a maximum value when the right atrial pressure falls to -2 to -4 mm Hg and remains at this maximum value down to infinitely low negative pressures. As the right atrial pressure rises to positive values venous return falls and reaches zero when the right atrial pressure has risen to equal the mean circulatory pressure. A venous return curve for the normal, intact dog has been tentatively formulated on the basis of these studies and previous studies in which individual points on the venous return curves of intact dogs have been measured.
