BACKGROUND Liver transplant is the only definitive treatment for many patients with end stage liver disease. Presence and severity of preoperative pulmonary disease directly affect the rate of postoperative complications of the liver transplantation. Arterial blood gas (ABG) measurement, performed in many transplant centers, is considered as a traditional method to diagnose hypoxemia. Because A...

Pulse oximetry data such as saturation of peripheral oxygen (SpO(2)) and pulse rate are vital signals for early diagnosis of heart disease. Therefore, various pulse oximeters have been developed continuously. However, some of the existing pulse oximeters are not equipped with communication capabilities, and consequently, the continuous monitoring of patient health is restricted. Moreover, even ...

OBJECTIVE This study investigates the validity of transabdominal pulse oximetry using a sheep fetal hypoxia model with fetal arterial hemoglobin saturation. METHODS Four pregnant ewes were anaesthetized and cannulated through the brachial artery to measure direct arterial blood saturation, SaO(2). Next, the transabdominal pulse oximeter was used to measure indirect measurement of the arterial...

Background and Study objective: Continuous perioperative monitoring of blood oxygen saturation via pulse oximetry is an established standard care. The incidence postoperative cognitive dysfunction (POCD) in orthopedic patients higher when compared to any other group hospitalized patients. Although its etiology remains unclear, factors such as thromboembolic complications may play a role. Thromb...

BACKGROUND The aim of this study was to collect important data on the time of oxygen saturation change in relation to skin flap color alteration using non-invasive pulse oximetry to evaluate its ability to provide continuous monitoring of skin flap perfusion. METHODS An experimental study on the monitoring of blood perfusion of 20 tube-island groin flaps of 10 male New Zealand rabbits was per...

OBJECTIVE The purposes of the study were to: (1) describe the aggregate strength of the relationship of arterial oxygen saturation as measured by pulse oximetry with the standard of arterial blood gas analysis as measured by co-oximetry, (2) examine how various factors affect this relationship, and (3) describe an aggregate estimate of the bias and precision between oxygen saturation as measure...

OBJECTIVES To compare pulse oximetry and Ankle-Brachial Index (ABI) with duplex ultrasonography as reference standard to determine the diagnostic accuracy for screening asymptomatic PVD in type 2 diabetes mellitus. METHODS This cross-sectional study was conducted in 2012 at tertiary hospital in Madurai among diabetic patients attending the medicine outpatient department (OPD). Type 2 Diabetes...

CASE We describe a case report of a 2-year-old boy presenting to the emergency department with cyanosis and agitation. There was no suggestive history of poisoning but parents reported the presence of an aquarium at the family dinner the night before, with an aquarium cleaner beside it. Physical examination at admission revealed central cyanosis without signs of respiratory distress. Oxygen sat...

OBJECTIVE To evaluate the accuracy of pulse oximetry as a screening tool for congenital heart disease in asymptomatic newborns. DESIGN, DATA SOURCES AND METHODS: Systematic review of relevant studies identified through MEDLINE, EMBASE, Cochrane Library, MEDION, and bibliographies of retrieved primary and review articles. Two reviewers independently extracted data on study characteristics, quali...
