FIG. 2

An example of vasospasm in a control ear with delayed partial recovery of CBF and DPOAE after release of a 3-minute IAA compression. The lower plot shows an approximate 6-minute postrelease delay in recovery of the CBF. The upper plot depicts the corresponding DPOAE recorded at 4 kHz, 8 kHz, and 12 kHz. Note that 4 kHz DPOAE recovered relatively quickly to precompression baseline values. At 8 kHz and, more dramatically, at 12 kHz, significant delays in recovery occurred with DPOAE stabilization below precompression baseline values.
