UNASSIGNED: OBJECT In contrast to @entity428 ( @entity428 ) in @entity131 ( @entity131 ), intraspinal pressure (ISP) after @entity1566 ( @entity1566 ) has not received the same attention in terms of waveform analysis. Based on a recently introduced technique for continuous monitoring of ISP, here the morphological characteristics of ISP are observationally described. It was hypothesized that the waveform analysis method used to assess @entity428 could be similarly applied to ISP. METHODS Data included continuous recordings of ISP and arterial blood pressure (ABP) in 18 @entity1 with severe @entity1566 . RESULTS The morphology of the ISP pulse waveform resembled the @entity428 waveform shape and was composed of 3 peaks representing percussion, tidal, and dicrotic waves. Spectral analysis demonstrated the presence of slow, respiratory, and pulse waves at different frequencies. The pulse amplitude of ISP was proportional to the mean ISP, suggesting a similar exponential pressure-volume relationship as in the intracerebral space. The interaction between the slow waves of ISP and ABP is capable of characterizing the spinal autoregulatory capacity. CONCLUSIONS This preliminary observational study confirms morphological and spectral similarities between ISP in @entity1566 and @entity428 . Therefore, the known methods used for @entity428 waveform analysis could be transferred to ISP analysis and, upon verification, potentially used for monitoring @entity1566 @entity1 .
