FIG. 3

An example of vasospasm in a control ear with a rapid partial recovery of CBF after a 3-minute IAA compression. In the lower plot, postrelease CBF quickly stabilized to approximately 65 percent below its precompression baseline levels. In the upper plot, DPOAE levels at 4 kHz and 8 kHz partially recovered in the immediate postrelease period, only to decrease into the noise–floor by 8 minutes after release; 12-kHz DPOAE never recovered.
