Critical closing pressure in subarachnoid hemorrhage: effect of cerebral vasospasm and limitations of a transcranial Doppler-derived estimation.
BACKGROUND AND PURPOSE Critical closing pressure (CCP) is thought to be jointly influenced by intracranial pressure and cerebrovascular tone. We examined how CCP is affected by cerebral vasospasm after subarachnoid hemorrhage (SAH). METHODS In 15 patients with vasospasm of the middle cerebral artery, CCP was calculated using 2 methods previously reported (ad modem Aaslid and Michel, indexed C...
متن کاملCardiac Complication Following Subarachnoid Hemorrhage
Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...
متن کاملCritical closing pressure in cerebrovascular circulation.
OBJECTIVE Cerebral critical closing pressure (CCP) has been defined as an arterial pressure threshold below which arterial vessels collapse. Hypothetically this is equal to intracranial pressure (ICP) plus the contribution from the active tone of cerebral arterial smooth muscle. The correlation of CCP with ICP, cerebral autoregulation, and other clinical and haemodynamic modalities in patients ...
متن کاملCritical closing pressure during midazolam-induced sleep.
The critical closing pressure (Pcrit) is the airway pressure at which the airway collapses and reflects the anatomical contribution to the genesis of obstructive sleep apnea. Pcrit is usually determined during non-rapid eye movement sleep at night, but has been determined under midazolam sedation during the day in the absence of sleep stage monitoring. Indeed, little is known about the effects ...
متن کاملCerebral vasospasm affects arterial critical closing pressure.
The effect of cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage (SAH) on critical closing pressure (CrCP) has not been fully delineated. Using cerebral impedance methodology, we sought to assess the behavior of CrCP during CVS. As CrCP expresses the sum of intracranial pressure (ICP) and vascular wall tension, we also explored its role in reflecting changes in vascular tone occu...
