(57) [Summary] [Purpose] To monitor patient hemodynamics and automatically administer circulatory agents as necessary to stabilize patient hemodynamics. [Configuration] The microcomputer 5 periodically captures the pulse wave of the patient via the pulse wave detection unit 200 and analyzes the frequency thereof. Then, when the amplitude and phase of the spectrum of the pulse wave satisfy a predetermined condition, the dosage unit 300 or 400 administers α blocker or β blocker to the patient, and maintains the patient's circulatory dynamic state in a stable state. |
