Physiological information display apparatus and physiological information display method

A physiological information display apparatus comprising:

• a heart rate acquisition unit configured to acquire a heart rate of a subject;
• a respiration rate acquisition unit configured to acquire a respiration rate of the subject;
• one or more processors configured to calculate:
• a hemodynamic parameter of the subject;
• and
• a respiratory variation of the hemodynamic parameter, based on a plurality of the hemodynamic parameters calculated in a predetermined period;
• and
• a display controller configured to output the respiratory variation to a display,
• wherein the one or more processors is further configured to calculate a heart rate in one respiration, using the heart rate and the respiration rate, the heart rate in one respiration being a heart rate included in one respiratory cycle,
• the display controller is further configured to output, to the display, a setting screen for setting a length of the predetermined period, the setting screen configured to display the heart rate in one respiration, and
• the one or more processors configured to:
• acquire setting information indicating contents set on the setting screen;
• set the length of the predetermined period based on the acquired setting information;
• and
• calculate the respiratory variation in the set predetermined period.
