Claim 12:
13. A physiological parameter processing apparatus comprising:
an input interface configured to acquire respiration data produced based on a respiratory gas that is obtained from at least one of a mouth or nose of a subject, the input interface being connected to a respiratory gas sensor configured to acquire the respiration data;
a processor configured to analyze in real time the respiration data acquired through the input interface, and to produce real-time analysis result data;
a display configured to acquire the real-time analysis result data from the processor, and to display the real-time analysis result data in real-time; and
a memory configured to store the real-time analysis result data,
wherein the processor is configured to analyze the respiration data by comparing the respiration data and a first value relating to the respiratory gas to analyze the respiration data in:
an expiration gas scan mode in which a second value that is on a minus side of the first value is detected;
an inspiration gas scan mode in which, after the process of the expiration gas scan mode, a third value that is on a plus side of the first value is detected; and
an expiration gas search mode in which, after the process of the inspiration gas scan mode, a fourth value that is on a minus side of the first value is detected, and

wherein the processor is further configured to calculate a respiration rate of the subject based on a number of expirations and inspirations of the subject analyzed in the expiration gas scan mode, the inspiration gas scan mode, the expiration gas search mode, the number of expirations and inspirations of the subject being detected within one minute, and to supply the calculated respiration rate to the display,
wherein the display is configured to display:
the respiration rate acquired from the processor as the real-time analysis result data,
the real-time analysis result data and a waveform of the respiration data adjacent to each other on a primary screen, and
past analysis result data acquired from the memory on a secondary screen.
