In patients admitted to the ICU for hypoxemic respiratory failure who receive supplemental oxygen, there are conflicting data showing increased or decreased mortality in treated with a lower oxygenation target compared higher target. One meta-analysis showed targets were preferable critically ill patients, but other trials stopped early due an increase lower-oxygenation groups and increases mes...

BACKGROUND The relationships between age and the life-supporting treatments use, and between gender and the life-supporting treatments use are still controversial. Using extracorporeal membrane oxygenation as an example of life-supporting treatments, the objectives of this study were: (1) to examine the relationship between age and the extracorporeal membrane oxygenation use; (2) to examine the...

Abstract The Paleocene Eocene Thermal Maximum (PETM) represents a major carbon cycle and climate perturbation that was associated with ocean de-oxygenation, in qualitatively similar manner to the more extensive Mesozoic Oceanic Anoxic Events. Although indicators of de-oxygenation are common for PETM, linked biotic turnover, global extent temporal progression is poorly constrained. Here we prese...

Extracorporeal membrane oxygenation is used in Sickle cell disease patients is unclear. We present a case of a 6 years old girl with homozygous hemoglobin SS disease complicated with chest syndrome. Oxygenation was maintained with two days of VA extracorporeal membrane oxygenation and 30 days of VV ECMO.

Preterm infants are at high risk of death and disability resulting from brain injury. Impaired cardiovascular function leading to poor cerebral oxygenation is a significant contributor these adverse outcomes, but current therapeutic approaches have failed improve outcome. We re-examined existing evidence regarding hypovolemia concluded that in the preterm infant loss plasma circulation results ...

High-frequency oscillatory ventilation (HFOV) seems ideal for lung protection in acute respiratory distress syndrome, but randomized trials have not shown a mortality reduction. The initial oxygenation response to HFOV appears to be associated with survival. Here, we discuss the mechanisms of oxygenation response to increases in airway pressure and the interpretation of the oxygenation response...

This study assesses the effects of transfusion of autologous or allogeneic blood on cerebral and tissue oxygenation during spinal surgery. Packed red blood cell transfusions are indicated to improve oxygen delivery to tissues. There are limited data demonstrating changes in tissue oxygenation with blood administration. Tissue (deltoid) and cerebral oxygenation were monitored using near-infrared...

A portable diffuse correlation spectroscopy (DCS) flowmeter has been extended to measure both tissue blood flow and oxygenation (namely, DCS flow oximeter). For validation purposes, calf muscle blood oxygenation during cuff inflation and deflation was measured concurrently using the DCS flow oximeter and a commercial tissue oximeter. The oxygenation traces from the two measurements exhibited si...

background: desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. the aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. methods: this interventional ...
