An unusual explanation for low oxygen saturation.
Pulse oximeters are now commonplace in modern medical practice, but we still need to be aware of their limitations. We present here a case of a 62-yr-old gentleman who underwent general anaesthesia for a recurrent parietal meningioma. He had received multiple general anaesthetics in the past. Persistent low pulse oximetry readings in the perioperative period, without any suggestion of respirato...
متن کاملDynamic equilibrium explanation for nanobubbles' unusual temperature and saturation dependence.
The dynamic equilibrium model suggests that surface nanobubbles can be stable due to an influx of gas in the vicinity of the bubble contact line, driven by substrate hydrophobicity, that balances the outflux of gas from the bubble apex. Here, we develop an alternate formulation of this mechanism that predicts rich behavior in agreement with recent experimental measurements. Namely, we find that...
متن کاملAn unusual explanation for episodic dyspnea.
An 88-year-old woman with a nonischemic cardiomyopathy, severe kyphoscoliosis, and an implantable cardiac defibrillator presented from her nursing home with dyspnea and hypoxemia. She had several recent hospitalizations for similar symptoms that were attributed to heart failure and pneumonia. On the day of presentation, she had severe dyspnea while eating breakfast. In the emergency department,...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
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 st...
متن کاملUnderstanding China: An Explanation for an Unusual Macroeconomy
China presents several macroeconomic patterns that appear inconsistent with standard stylized facts about economic development and hence inconsistent with the standard growth model. We show that Chinese macroeconomic patterns instead appear consistent with an objective of maximizing output in non-competitive factor markets. In short, China appears to successfully follow the stated output object...
