Evaluation of Endothelial Function on Atherosclerosis using Perfusion Index from Pulse Oximeter
BACKGROUND Endothelial dysfunction is vascular phenomenon that plays an important role in atherosclerosis development. With the purpose of improving the prevention and treatment of atherosclerotic diseases, the searching for accurate, practical and cheaper methods for evaluating endothelial function have become of interest. OBJECTIVES Verify the potential of Peripheral Perfusion Index from pu...
متن کاملAccuracy of pulse oximeter perfusion index in thoracic epidural anesthesia under basal general anesthesia.
OBJECTIVE To observe the change of PVI after thoracic epidural block on the basis of general anesthesia. METHODS In 26 patients undergoing elective upper abdominal operations, changes of SVI, PVI, SVV, PPV and CVP were monitored immediately before and 10 minutes after T8-9 thoracic epidural anesthesia on the basis of general anesthesia. The definition was that patients with ΔSVI greater than ...
متن کاملAssessment of Pulse Oximeter Perfusion Index in Pediatric Caudal Block under Basal Ketamine Anesthesia
Whether pulse oximeter perfusion index (PI) may be applied to detect the onset of caudal block in pediatric patients under ketamine intravenous basal anesthesia is investigated. 40 ASA I, 2-8-year-old boys scheduled for elective circumcision surgery were randomized into two groups. Group I: 20 patients were anesthetized by 2 mg·kg(-1) ketamine intravenous injection (IV) followed by caudal block...
متن کاملEvaluation of the Ohmeda 3700 pulse oximeter.
Arterial oxygen saturation values (Sao2) from 60% to 98% were measured by the Ohmeda 3700 pulse oximeter with the three types of probe available and compared with values of oxygen saturation estimated from direct arterial sampling (arterial oxygen and carbon dioxide tensions and pH) on 65 occasions. The response time of the oximeter was measured after a sudden rise in inspired oxygen concentrat...
متن کاملEvaluation of a new pulse oximeter sensor.
BACKGROUND A new forehead noninvasive oxygen saturation sensor may improve signal quality in patients with low cardiac index. OBJECTIVES To examine agreement between oxygen saturation values obtained by using digit-based and forehead pulse oximeters with arterial oxygen saturation in patients with low cardiac index. METHODS A method-comparison study was used to examine the agreement between...
