Fluid responsiveness detection device and method

A fluid responsiveness detection device, comprising:

• a breathing signal acquisition module, a hemodynamic signal acquisition module and a fluid responsiveness detection module, wherein the breathing signal acquisition module and the hemodynamic signal acquisition module operate under a breathing mode of a subject being any one of:
• a spontaneous breathing mode, a spontaneous breathing and machine-controlled breathing mode, or a machine-controlled breathing mode;
• the hemodynamic signal acquisition module is configured to acquire at least one hemodynamic signal of the subject;
• the breathing signal acquisition module is configured to obtain at least one breathing signal of the subject, the breathing signal comprising a respiratory cycle;
• and
• the fluid responsiveness detection module is configured to determine the fluid responsiveness of the subject based on the breathing signal and the hemodynamic signal,
• wherein the fluid responsiveness detection module is further configured to determine a respiratory variation and a hemodynamic variation of the subject based on the respiratory cycle, and determine the fluid responsiveness of the subject based on the respiratory variation and the hemodynamic variation.
