Invite you to refer. | 7 Cerebral Autoregulation Marek Czosnyka PhD Enrique Carrero Cardenal PhD INTRODUCTION Patients with Drain rnhaies may have impaired cerebral autoregulation. The extent of this impairment may fluctuate with time. A repeatable noninvasive method of monilormg ofautore lvtoay reserve is needed.
