OBJECTIVES Pursuing health goals in very old age is a challenging task that may be undermined by conflicted goal engagement involving mismatched primary (behavior-focused) and secondary (motivation-focused) control striving. Our study explored whether one potentially detrimental combination of control strategies (low primary control/high secondary control) compromised 3-year indicators of every...

UNLABELLED Oxygen is a neonatal health hazard that should be avoided in clinical practice. In this review, an international team of neonatologists and nurses assessed oxygen saturation (SpO2 ) targeting in preterm infants and evaluated the potential weaknesses of randomised clinical trials. CONCLUSION SpO2 of 85-89% can increase mortality and 91-95% can cause hyperoxia and ill effects. Neithe...

AIM To determine normative data for arterial oxygen saturation, measured by pulse oximetry (SpO2), in healthy full term infants throughout their first 24 hours of life. METHODS Long term recordings of SpO2, pulse waveform, and breathing movements were made on 90 infants. Recordings were analysed for baseline SpO(2), episodes of desaturation (SpO2 /= four seconds, ...

Four venous hemoglobin oxygen saturation monitors, two of which provide hemoglobin monitoring, were evaluated and compared to a performance standard (control) during cardiopulmonary bypass (CPB). The CDI 100 Hematocrit/Saturation Monitor, CDI 400, Cobe Hematocrit/Saturation Monitor, and the Baxter Bentley OxySat values were compared to the Radiometer Copenhagen OSM3 Hemoximeter and the Damon In...

We determined the millimolar absorptivities of the four clinically relevant derivatives of fetal and adult human hemoglobin in the visible and near-infrared spectral range (450-1000 nm). As expected, spectral absorption curves of similar shape were found, but the small differences between fetal and adult hemoglobin absorptivity were important enough that they should be taken into account in mul...

The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the period 1997 to 2006, using generalised additive models (GAMs) and generalised additive mixed models (GAMMs). Spatial and temporal variations in DO saturation and the current se...

Pulse oximetry is becoming popular for measuring oxygen saturation of haemoglobin in paediatric patients. There are no reference values for children living at high altitudes, and the aim of this study was to determine the values of oxygen saturation of haemoglobin in healthy children in Bogota (2640 m above sea level). The saturation was determined in 189 children aged 5 days to 24 months with ...

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 ...
