PCT No. PCT/GB91/01807 Sec. 371 Date Feb. 13, 1993 Sec. 102(e) Date Feb. 13, 1993 PCT Filed Oct. 16, 1991 PCT Pub. No. WO92/06632 PCT Pub. Date Apr. 30, 1992.A method and apparatus for providing a measure of the depth of anaesthesia. A series of R-waves are analyzed using circular statistics to derive a measurement vector length representing the R-R variation of the sample. The Rayleigh Test is applied to determine a reference vector length from a predetermined probability level and the number of R-waves in the analyzed series. The measurement vector length is compared to the reference vector length to derive a measure of the death of anaesthesia. |
