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.

Acute hypertensive response (AHR) affects more than 60% of patients with ischemic stroke and is associated with poor outcomes. We hypothesized that its development is related to arterial stiffening. "...
Stroke-associated pneumonia (SAP) is associated with poor functional outcome in patients with acute ischemic stroke (AIS). The objective of this study was to identify predictors of SAP in patients und...
Arterial wall elasticity including the circumferential and longitudinal modulus is a measure of sub-clinical cardiovascular disease; the circumferential modulus is increased in acute ischemic stroke (...
The cause of ischemic stroke or transient ischemic attack (TIA) remains unclear after initial cardiac monitoring in approximately one-third of patients. Randomized controlled trials (RCTs) showed that...
Intra-arterial treatment (IAT) for acute ischemic stroke caused by intracranial arterial occlusion leads to improved functional outcome in patients treated within 6 hours after onset. The influence of...
The purpose of this study is to ultimately prevent injuries to nerves during surgical procedures. Living donor liver transplant or hepatectomy (removal of a piece of the liver) patients wi...
The study objective is to assess the accuracy of Earlysense contactless monitoring to detect changes in blood pressure vs. Gold reference method / devices including ambulatory blood pressu...
Invasive blood pressure monitoring is achieved by cannulating an artery and transducing the pressure. During arterial cannulation the artery can be located by palpation, but use of ultraso...
The purpose of this study is the evaluation and comparison of blood pressure variability indices and ambulatory arterial stiffness index obtained by ambulatory blood pressure monitoring as...
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 ...
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.
