<P>PROBLEM TO BE SOLVED: To provide a sleep apnea syndrome testing apparatus capable of highly accurately determining the type of apnea in a simple constitution. <P>SOLUTION: A fingertip sensor 1 on a fingertip part A, or an apnea syndrome testing apparatus, consists of pulse wave sensors 1a and 1b, sympathetic skin response (SSR) potential sensors 1c and 1d and a body earth electrode 6, and the type of the apnea is determined based on a curve expressing a change in an amplitude value of oxygen saturation SpO<SB>2</SB>measured by the pulse wave sensors 1a and 1b, a change in a fluctuation coefficient of pulse wave amplitudes, a respiration curve extracted from a pulse wave amplitude change, and the presence/absence of the potential detected by the sympathetic skin response (SSR) potential sensors 1c and 1d. <P>COPYRIGHT: (C)2009,JPO&INPIT |
