Abstract: A respiration control apparatus connected to a controlled body includes a respiration circuit having an inhalation circuit and an exhalation circuit. The inhalation circuit includes a first solenoid-operated valve and a first check valve. The exhalation circuit includes a vent valve, a dehumidifying chamber, a pressure detector, a second check valve, and a second solenoid-operated valve. A central processor closes the first solenoid-operated valve and the second solenoid-operated valve based on a respiration control signal supplied from a synchronizing signal output control device, disconnecting the respiratory system of the controlled body from the outside of the respiration control apparatus.

Abstract: The level of a respiration signal obtained from a laser sensor or the like is indicated on a respiration monitor according to an output condition set by synchronizing signal output control device. While the level of the respiration signal is indicated on the respiration monitor, a synchronizing signal output device outputs a synchronizing signal according to the output condition and the respiration signal to an X-ray control device, which controls a high-voltage generating device to energize an X-ray source to apply X-rays to an examinee.
