Monitoring the oxygenation status of patients with poor peripheral perfusion or ischemic peripheries is challenging in view of unreliable or unrecordable pulse oximeter data. In this article we describe a very simple and innovative technique of using the arterial line for reliable recording of arterial oxygen saturation (SpO(2)) in such patients. We conclude that the arterial line can be used as an extension of the artery and SpO(2) may be reliably measured using the arterial line in such patients as long as the blood in the arterial tubing is pulsatile and a good contact is ensured between the arterial tubing and the sensor of the pulse oximeter.

Patients with rheumatoid arthritis (RA) are at a higher risk of arterial disease, endothelial dysfunction, and vascular inflammation than the general population. Therefore, these patients are prone to...
Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians, whereas whites tend to have more extracranial lesions. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been ...
Ischemic stroke may be the first manifestation of cerebrovascular disease. However, subclinical organ complications of underlying arterial stiffness and hypertension may coexist and stratify outcome. ...
Intravenous recombinant tissue plasminogen activator continues to be first-line therapy for patients with acute ischemic stroke presenting within the appropriate time window, but one potential limitat...
Lack of nightly blood pressure (BP) reduction is associated with increased cardiovascular risk. The aim of this study was to assess the association of nightly BP reduction with arterial stiffness in y...

The use of ultrasound is becoming widespread to guide the placement of arterial lines for both vascular access and regional anesthesia in the field of anesthesia. Arterial line placement ...
The purpose of this study was to compare the Continuous Non-invasive Arterial Pressure (CNAP) monitor with the gold standard of invasive arterial pressure monitoring.
The purpose of this study is to determine whether continuous non-invasive arterial pressure (CNAP) monitoring is beneficial to maintain maternal hemodynamic stability and improve the outco...
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)
The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.
Blocking of a blood vessel by CHOLESTEROL-rich atheromatous deposits, generally occurring in the flow from a large artery to small arterial branches. It is also called arterial-arterial embolization or atheroembolism which may be spontaneous or iatrogenic. Patients with spontaneous atheroembolism often have painful, cyanotic digits of acute onset.
Physiologic or biochemical monitoring of the fetus. It is usually done during LABOR, OBSTETRIC and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery.
