In the River Brett, Eastern England, over the period 1955–1998 there was a significant long-term decline in dissolved oxygen (DO), as well as increases in TON (total oxidised nitrogen) and SRP (soluble reactive phosphorus). Flow decreased from 1963 to 1998. Field studies in 1998–2000 sho...
Children with epiglottitis and airway restriction may drool and mainly breathe by mouth Common signs and symptoms of hypoxemia Hypoxemia specifically refers to low oxygen levels in the blood, which can lead to the following symptoms: Shortness of breath (dyspnea): This is often the most prominent...
Hyperbaric oxygen for chronic wounds Chronic wounds are common and present a health problem with significant effect on quality of life. The wide range of therapeutic strategies for such wounds... P Kranke,Michael H Bennett,I Roeckl-Wiedmann,... - 《Cochrane Database of Systematic Reviews》 被引...
Furthermore, the mainstay of COVID-19 therapy includes provision of oxygen for the severely ill and intensive care for those who are critically ill, but over half of health facilities in resource limited settings have insufficient oxygen supply and pulse oximetry, and dedicated paediatric intensive...
We used the duration of neonatal hospital stay as the measure of severity of neonatal illness because it represents an index of immaturity and severity of respiratory distress syndrome such as oxygen and ventilator dependence (22,23). Indices of postnatal growth included distance growth between the ...
clot lodges in the pulmonary circulation. This condition, known as a pulmonary embolism or PE, obstructs blood flow through the lungs, interfering with oxygen uptake.Malformations of the heart or lung blood vessels that lead to blood bypassing the lungs can also lead to varying degrees of ...
A lack of oxygen in cells can lead to a condition known as hypoxia, which can disrupt normal cellular functions and ultimately result in cell damage or death [3]. The cellular response to hypoxia is a complex process that involves both physiological and pathological adaptations, such as ...

27,64-68 Mechanisms for the association of air pollutants with stillbirth may involve alterations in oxygen transport, DNA damage, or placental injury.69-72 The cause-specific analysis by Ebisu et al39 of stillbirths reinforces the apparent association of injury to the fetal-placental unit with ...
In predefined subgroup analyses, there were no statistically significant differences in treatment effects between birth weight strata (400-749 g vs 750-999 g), sex, and high or low institutional pulse oximetry oxygen saturation target range subgroups with regard to the primary end point, the incide...
