Effect of Maximal Breath Hold Apnea on Pial Artery Pulsation and Subarachnoid Width in Human

Little is known about intracranial pressure (ICP)-cerebral hemodynamic interplay during maximal breath-hold apnea. A recently developed method based on near-infrared transillumination/backscattering sounding (NIR-T/BSS) noninvasively measures changes in pial artery pulsation (cc-TQ) as well as subarachnoid width (sas-TQ) in humans. Changes in sas-TQ correlate with ICP to a considerable extent, whereas cc-TQ reflects the functional status of the pial artery. We tested the complex response of the pial artery and subarachnoid width to apnea using this method.
