A respiration characteristic analysis apparatus includes a bioelectrical impedance determiner adapted for determining a first bioelectrical impedance at the upper body trunk of a human subject including the upper lobes of the lungs of the human subject and excluding the abdomen of the human subject and a second bioelectrical impedance at the middle body trunk of the human subject including the median and lower lobes of the lungs of the human subject and the abdomen of the human subject and an analyzer adapted for analyzing a respiration characteristic of the human subject on the basis of change over time in each of the first bioelectrical impedance and the second bioelectrical impedance determined by the bioelectrical impedance determiner.
