Background Central (ScVO2) and mixed venous oxygen saturation (SvO2) and blood lactate are useful measurement tools for evaluating the degree of hypoperfusion in patients with different disease processes. The aim was to study incidence of both low as well as high ScvO2 and assessed their relationship to markers of tissue hypoxia, course and outcome in patients undergoing elective cardiac surgery.

BACKGROUND AND PURPOSE We measured arterial oxygen saturation (SaO(2)) during eating in acute stroke patients to establish the frequency of any meal-related hypoxemia, which could further damage already vulnerable brain tissue. METHODS Stroke patients (</=12 days from stroke onset) classified as "safe to feed orally" were compared with elderly hospitalized (for nonneurological causes) and you...

AIMS AND OBJECTIVES The aim of this literature review was to provide a clear definition of central venous oxygen saturation (ScvO₂), highlight the differences between ScvO₂ and mixed venous oxygen saturation (SvO₂), show how it can be used clinically and the effect central venous oxygen saturation has on mortality. BACKGROUND Many articles concentrate on the individual aspects of ScvO₂, such ...

Pulse oximeters are widely used for noninvasive monitoring of oxygen saturation in arterial blood hemoglobin. We present a transmittance pulse oximetry system based on near-infrared (NIR) laser diodes (750 and 850 nm) for monitoring oxygen saturation of arterial blood hemoglobin. The pulse oximetry system is made up of the optical sensor, sensor electronics, and processing block. Also, we show ...

BACKGROUND Single-lung ventilation (SLV) during thoracic surgery causes important cardiopulmonary disturbances. Absolute cerebral oximetry was used to determine the incidence and magnitude of the decrease in cerebral oxygen saturation (Sct(o(2))) in patients undergoing SLV during thoracic surgery. METHODS Data were obtained from 20 consecutive patients undergoing thoracic surgery and necessit...

Background: One of the most important methods of complementary medicine is music and phonotherapy and one of the most beautiful sounds is the sound from the recitation of the Quran. We aimed to investigate the effect of the sound of the Quran on physiological responses in preterm infants. Materials and Methods: <...
